Objective:Dysfunctional voiding (DV), which is explained as an incoordination between the external urethral sphincter and the bladder, is a situation developing in neurologically normal children. Serotonin has some effects on the lower urinary tract which cannot be fully explained. The selective 5-hydroxyindoleacetic acid (5-HIAA) agonist improves voiding efficacy in the rat model with voiding dysfunction as serotonin. Serotonin decomposes to 5-HIAA which excreted from urine. We considered that a problem in neuromodulator levels can lead to DV and evaluated the levels of 5-HIAA in urine.Materials and Methods:Our study included 130 children aged 5-15 years who were diagnosed with DV and 48 children with no urological complaints as controls. Urine samples were taken only once in control group, and 3 times [before and after the biofeedback treatment (sixth month and twelfth month)] in the study group to determine the difference and the interaction between 5-HIAA and biofeedback therapy.Results:Biofeedback therapy was found to be an effective method in the treatment of DV. However, there was no significant difference in the level of mean urine 5-HIAA/creatinine (u5-HIAA/Cr) between study (6.139±3.652) and control groups (6.374±4.329) (p=0.751). The mean u5-HIAA/Cr levels in the DV group at baseline and at the end of biofeedback therapy (6th month) were 6.249±4.132 and 6.19±4.715, respectively (p=0.951). The mean u5-HIAA/Cr levels in the DV group at baseline and at 12 months were 5.901±3.291 and 6.644±4.206, respectively (p=0.557). There was no significant difference in u5-HIAA/Cr levels between pre-treatment and post-treatment in the DV group.Conclusion:We still do not know if a problem at the level of neurotransmitter metabolite in the central nervous system plays a role in the etiology of DV. We evaluated this relationship, but we could not find a significant result. New studies are needed to get more information about the role of neuromodulators in the etiology and treatment of DV.

Cystoscopy is a safe diagnostic procedure commonly used to evaluate lower urinary tract symptoms. This can cause pain, anxiety, and dissatisfaction in patients undergoing cystoscopy.The aim of this study was to compare the effects on pain, anxiety, and satisfaction of distraction methods used during cystoscopy.Single-center, open-label, randomized, parallel-group trial.Cystoscopy unit of a training and research hospital in Turkey.Male patients ≥18 years of age who underwent rigid cystoscopy for the first time.A total of 120 male patients were recruited and randomized into four groups as music, stress ball, video, and control group. Data were collected using visual analog scale for pain and satisfaction, State-Trait Anxiety Inventory for anxiety, and hemodynamic parameters. The primary outcome was the difference with respect to pain scores among intervention groups. Other outcome measures were anxiety and satisfaction scores.Pain severity during cystoscopy was found to be significantly lower in the intervention groups than the control group. In the video group, the severity of pain during cystoscopy was also found to be significantly lower than music and stress ball groups (p = 0.006, p 0.001). After cystoscopy, anxiety levels were significantly lower and satisfaction levels were significantly higher in the intervention groups than in the control group. Anxiety levels were significantly lower in the video group than music and stress ball groups (p 0.001, p 0.001). Satisfaction levels were also significantly higher after cystoscopy in the video group than in the music and stress ball groups (p = 0.018, p = 0.018).According to this study, distraction methods used during rigid cystoscopy were found to have a reducing effect on pain, anxiety, and dissatisfaction. As the results of the study are evaluated, video should be recommended to be the first preferred distraction method during rigid cystoscopy.

Summary Introduction Lower urinary tract dysfunction (LUTD) is a situation that often disrupts the quality of life (QoL) of both the child and the family with daytime and nighttime incontinence. Although the first-line treatment option for children with LUTD is standard urotherapy, biofeedback therapy can be performed in children in which standard urotherapy failed. Objective We studied the biofeedback success in children with LUTD according to parents' expressions. Methods We retrospectively analyzed our hospital records of children who were diagnosed with LUTD between 2005 and 2017. In total, 281 patients, refractory to standard urotherapy were included into the study and directed to biofeedback treatment. Their parents completed the dysfunctional voiding symptom scores (DVSS) before and after biofeedback therapy. Results At the end of the six-month follow-up period, all voiding disorders and voiding patterns were evaluated. According to DVSS, QoL tools before biofeedback treatment 48 (17%) parents appraised that LUTD caused no effect in their children's daily life, 104 (37.8%) expressed little effect, 89 (31%) moderate effect, and 40 (14.2%) serious effect. And, 120 (43%) parents expressed no effect, 95 (34%) little effect, 51 (18%) moderate effect, and 15 (5%) serious effect (P = 0.001) after biofeedback therapy. Biofeedback therapy affected positively the daily life of LUTD's family. The less serious the effect of LUTD on these children's family, the more success rate of biofeedback therapy. The effect of biofeedback therapy was less successful in moderated and serious affected families. Conclusions Biofeedback treatment is a non-invasive and effective treatment modality for improving the QoL for LUTD families who were less suffered from LUTD. Summary Table .

Objective To examine whether voided volume (VV) could change the uroflow patterns and result in children with lower urinary tract dysfunction (LUTD). Methods Between January 2009 and May 2010, the children with LUTD were enrolled in this study. Uroflowmetry (UF) combined with electromyography (EMG) was performed two times and was reviewed independently by two urologists. UF-EMG curves were classified as bell, staccato, intermittent, plateau, and tower. Patients' expected bladder capacity (EBC) and VV were recorded. Patients were divided into four groups according to their VV and EBC. Group 1, VV 125% of EBC. Results A total of 143 patients underwent UF-EMG at least two times and 382 results were obtained. Groups 1, 2, 3 and 4 consisted of 27, 60, 27 and 29 children, respectively. The percentages of normal, intermittent, plateau voiding patterns were 58.5, 12.8, 7.1% in group 1; 79.8, 5.4, 1.8% in group 2; 59.2, 8.5, 2.8% in group 3; and 37.2, 5.1, 2.6% in group 4, respectively. The percentages of staccato and tower pattern were 1.4, 20% in group 1; 9.1, 3.6% in group 2; 30, 0% in group 3; and 55.1, 0% in group 4, respectively. The rate of tower shape curve decreased as voided volume increased, but the rate of staccato curve increased as voided volume increased. Conclusions In case of exceeding the EBC, the test should be repeated with normal VV when UF results are being evaluated.

Background: To report the first case of the spontaneous appendicovesical fistulas' (AVF) repair with robot assisted laparoscopy. Case Presentation: A 29-year-old male patient with urgent persistant bacteriuria and dysuria was referred to our clinic. Physical examination and blood tests were normal. He had used various antibiotics due to recurrent UTI for about 20 years. Computed tomography revealed the fistula tract between the distal end of the appendix and right lateral wall of the bladder dome. He was successfully treated with robot-assisted laparoscopic repair. Following this surgery, the patient's complaints were resolved completely. Conclusion: AVF is the rare condition. Robot-assisted laparoscopy repair of AVF is safe and effective treatment option.

In the pediatric population, there have been significant improvements in the treatment of stones in recent years. Conventionally, ureteroscopy (URS) and/or retrograde intrarenal surgery are techniques performed with fluoroscopy. When using fluoroscopy, problems, including malignancy, may arise because of radiation exposure in the patient, physician, and operation room staff. The aim of this study is to evaluate the possibility of ureteroscopic treatment without fluoroscopy in children with ureteral and renal stones.Between December 2010 and April 2017, pediatric patients were enrolled in this study. Data were retrospectively evaluated. URS was performed by the experienced surgeons in our center. Fluoroscopy was not routinely used during the operations. Demographic data, perioperative parameters, and success and complication rates were evaluated.Sixty-seven renal units from 61 patients were operated on. URS without fluoroscopy was achieved in 95.0% of 61 patients (95.5% of 67 renal units). Three patients needed fluoroscopy during the operation. The mean stone size was 12.4 ± 5.3 mm, and the mean operation time was 41.9 ± 15.1 minutes. The success rates in the postoperative first and third mounts were 82.1% (55 renal units) and 88.0% (59 renal units), respectively. For 10 patients, second-session URS without fluoroscopy was needed. Clinically insignificant residual fragments were detected in three patients. There were no major complications.URS without fluoroscopy for ureteral and renal stones in pediatric patients can be safely and effectively performed in experienced centers.

Introduction: We aimed to evaluate whether or not mitomycin-C (MMC) has an antifibrotic effect on transforming growth factor-beta (TGF-β)-induced Peyronie’s disease (PD) in a rat model.Methods: Eighteen 12-week-old male Sprague-Dawley rats were divided into three groups: Group 1=TGF-β1 (n=7); Group 2=TGF-β1+MMC (n=7); and Group 3=Sham group (0.25 ml bovine serum albumin injected) (n=4). All groups were sacrificed on the sixth week of the procedure and their penises were excised. All penis specimens were evaluated semi-quantitatively and quantitatively with histochemical, immunohistochemistry, and image analysis.Results: Both Group 1 and Group 2 had significantly higher fibrosis scores and lower elastic fibers in both outer surface of tunica albuginea (TA) and subsinusoidal area compared with Group 3. When compared with Group 1, the amount of collagen was significantly decreased in Group 2. Intracavernosal MMC injection (Group 2) ended up with lower elastic fibers when compared with Group 1. According to the quantitative analyses, when compared with Groups 1 and 3, lower dorsal, ventral, and trabecular thickening values were seen in Group 2. These parameters were only statistically significant when compared with Group 1, suggesting the antifibrotic effect of TGF-β1-induced fibrosis. Both Groups 1 and 2 showed lower decorin staining levels in subsinusoidal areas of tunica albuginea (SATA) and subsinusoidal areas of trabecular wall (SATW) when compared with Group 3. The statistically significant difference was only detected between Group 1 and Group 3.Conclusions: Our study demonstrates the antifibrotic effects of MMC on PD. Further clinical studies are necessary to make inferences regarding its clinical use.

Objective To compare the barbed polyglyconate suture (BPS) with 2 commonly used conventional sutures, this prospective randomized trial was designed. The sutures applied in the urinary collecting system, in terms of long-term histopathologic and macroscopic suture material features. Materials and Methods Eight female and 6 male New Zealand rabbits were included in the study. Each animal served as its own control and was subjected to cystotomy. Watertight running cystorrhaphies were performed using 3 different sutures in a randomized fashion, namely Monocryl, Vicryl, and V-Loc 90. Seven animals were sacrificed after the third and 7 after the sixth week. Macroscopic and histopathologic examinations were performed. Tissue reaction, like inflammation and fibrosis, around the sutures were evaluated. Friedman and Wilcoxon signed ranks test was used for the statistical analysis. Results The BPS demonstrated no adhesion. However, in the six-week group, stone formation was recorded on 4 BPS and 1 Vicryl thread, a difference being statistically significant (P = .039). Additionally, in the third- and in the sixth-week group, 1 (P = .368) and 3 (P = .050) BPS threads migrated, respectively. The histopathologic analysis revealed less inflammation and fibrosis associated with the BPS thread in both the third and the sixth-week groups (P = .010 and P = .002, respectively). Conclusion The BPS appears to be superior to conventional sutures in terms of local inflammation and fibrosis. However, suture migration and stone formation following collecting system closure could be potential predicaments.

Introduction: Our goal was to evaluate benign and malignant lesions and testicular intraepithelial neoplasia (TIN) in the neighbouring normal- appearing testis tissue in men who underwent radical orchiectomy for testicular mass with a pathologic tumour size of ≤3cm.Methods: In this retrospective, multicentre study, data of 252 patients from 11 different institutions were included. Patients were divided into three groups based on tumour size: Group 1 (0‒1 cm; n=35), Group 2 (1.1‒2 cm; n=99), and Group 3 (2.1‒3 cm; n=118). Benign lesions and TIN were sought in the neighbouring testicular tissue and compared between groups.Results: Mean patient age was 32.3 years. Benign lesions were reported in 54.3%, 33.3%, and 14.4% of Groups 1, 2, and 3, respectively (p0.05 for Groups 2 vs. 3). Multifocality was detected in 8.6%, 4%, and 0% of Groups 1, 2, and 3, respectively (p0.05 for Group 1 vs. Group 2). A tumour cutoff size of 1.5 cm was found to be significant for detecting benign tumour. TIN and multifocality rates were similar in patients with a tumour size of ≤1.5 vs.>1.5 cm (p>0.05).Conclusions: Benign lesions and TIN in the neighbouring testis were significantly decreased and multifocality was increased in patients with a tumour mass size of ≤1 cm. Testis-sparing surgery should be performed with caution and a safety rim of normal tissue should also be excised.

Aim: Robotic assisted laparoscopic partial nephrectomy (RALPN) is promising option for RCC treatment with favorable outcomes. In this present study we aimed to compare the incidence of (AKI) acute kidney injury measured by AKIN (Acute Kidney Injury Network) criteria between open partial nephrectomy (OPN), laparoscopic partial nephrectomy (LPN) and RALPN procedures with zero ischemia periods. Material and Methods: The medical records of 88 patients with renal mass who underwent OPN, LPN and RALPN at our institution [24 female/64 male; median age of 55 (IQR: 46–65) years] were evaluated retrospectively. AKI was defined by AKIN criteria. Results: Twenty-six patients underwent OPN, 32 LPN and 30 patients RALPN. Mean preoperative creatinine was 0.92 ±0.43 mg/dl, mean hemoglobin level was 14.0±1.9 g/dl. Total of 19 patients developed AKI according to the AKIN criteria, all of those had stage 1 AKI, 10 (53%) in OPN, 7 (3%) in LPN and 2 (11%) in RALPN group (p=0,004). Multivariate regression analysis adjusted by age and gender showed that operation time per minute [1.02 (CI 95%, 1.00, 1.04) p=0.04], fluid administered as ml/kg/hour [1.003 (CI 95%, 1.000, 1.006) p=0.04], red blood cell transfused as unit [1.27 (CI 95%, 1.07, 1.52) p=0.006] and operation type as RALPN surgery versus OPN and LPN [0.11 (CI 95%, 0.02, 0.58) p=0.01] were significantly associated with development if AKI.Conclusion: Robot assisted partial nephrectomy is more favorable approach compared to OPN and LPN with lower operation time and lower hemoglobin loss.

Aims Enuresis is a child older than 5 years wetting in discrete portions during sleep. It has two subgroups: monosymptomatic enuresis nocturna (MSEN) and non-monosymptomatic enuresis nocturna (NMSEN). In this research, we specifically aimed to examine the effect of biofeedback in NMSEN. Methods We retrospectively analyzed the hospital records of 182 children with NMSEN who were refractory to urotherapy modifications and directed to biofeedback therapies between 2005 and 2010. Enuresis before and after biofeedback therapies was evaluated. One or less enuretic night in a month was defined as success. Results There were 118 (64%) girls and 64 (35%) boys. With biofeedback therapy, 117 of 182 patients recovered with a success rate of 64% (P

OBJECTIVE: To determine a paradigm that will be helpful for urologists to manage fibrous pseudotumors, which are a very rare condition of the testis. MATERIAL AND METHODS: We retrospectively evaluated the patients with fibrous pseudotumors in our uropathological database from 1995 to 2013. Patients who had tumor markers and ultrosonography (USG) screening before surgery and a final pathology report of a fibrous pseudotumor were included in the study. RESULTS: In total, 838 patients with a testis mass were evaluated. Only 6 of these patients met the inclusion criteria. The mean age was 34 years (min: 20, max: 72). Serum tumor markers were in the normal range for all patients. The scrotal tumors were not clearly related to the testis parenchyma, and the radiologists could not definitively determine the nature of the masses (benign or malignant). A concomitant hydrocele was detected in 2 patients. After inguinal exploration, radical orchiectomy was performed in one patient with an ipsilateral atrophic testis, and biopsies were taken from the lesions for frozen section analysis in the other 5 patients. Pathologists reported benign tumors for all of these patients based on the frozen sections, and testicular sparing surgery was then performed in these 5 patients. CONCLUSION: If scrotal tumors are detected by ultrasonography in patients with normal tumor markers, and the tumor cannot be clear distinguished from the testis, these patients might have a fibrous pseudotumor, and organ-sparing surgery can be performed on these patients.

Relapse after cessation of desmopressin is an important problem in treating patients with enuresis. Structured withdrawal of desmopressin tablets has been shown to decrease relapse rates. However, scientific data are lacking on the structured withdrawal of the fast melting oral formulation of desmopressin. We compared relapse rates of structured withdrawal using placebo and direct cessation in a population of patients with enuresis who were desmopressin responders.Patients diagnosed with enuresis and responding to desmopressin from 13 different centers were involved in the study. Patients were randomized into 4 groups. Two different structured withdrawal strategies were compared to placebo and direct withdrawal. Sample size was estimated as 240 (60 patients in each group), with a power of 0.80 and an effect size of 30%. Randomization was performed using NCSS statistical software (NCSS, Kaysville, Utah) from a single center. The relapse rates of the groups were compared using chi-square testing. Logistic regression analysis was performed to define the independent factors having an effect on relapse rates.Desmopressin treatment was initiated in 421 patients, and 259 patients were eligible for randomization. Relapse rates were 39 (1%) and 42 (4%) for the structured withdrawal groups, which were significantly less than for direct withdrawal (55, 3%) and placebo (53, 1%). Logistic regression analysis revealed that initial effective dose of 240 μcg, greater number of wet nights before treatment and nonstructured withdrawal were associated with higher relapse rates.We found that structured withdrawal with the fast melting oral formulation of desmopressin results in decreased relapse rates. Application of a structured withdrawal program was also an independent factor associated with reduced relapse rates, together with lower initial effective dose and number of wet nights per week. Relapse after cessation of desmopressin is an important problem, and in this study structured withdrawal was observed to be associated with decreased relapse rates compared to placebo and direct withdrawal.

Objective Our goals were to assess long-term outcome for patients with posterior urethral valves (PUV) and determine the impact of the timing of diagnosis. Patients and methods We reviewed the hospital records for patients with PUV treated in 1994–2008. Only those patients diagnosed, treated surgically, and followed clinically at our center were included. Results There were 52 patients with PUV. Thirty-nine were diagnosed by 1 year of age (early diagnosis cohort), while 13 were diagnosed after 1 year (late diagnosis cohort). Mean follow up after valve operation was 7.2 years (range 15 months–14 years). Chronic renal failure rates were not statistically different between the early and late diagnosis groups after surgical intervention: 48% (14/29) vs 25% (3/12), P = 0.30. Among the early diagnosis cases, 10% (3/29) eventually required renal transplant, while no child in the late diagnosis group has developed end-stage renal disease to date ( P = 0.55). Conclusions Gestational age at diagnosis is an important predictor of postnatal renal outcome. Our results suggest that diagnosis after 1 year of age is associated with a lower risk of developing renal insufficiency on long-term follow up.

Aims To examine whether obstruction changes the expression of prostaglandins (PGs) in bladder, intravesical low-dose aspirin could be used as a new route of drug administration, this way of administration influences PGs' expression, and contractile function of the bladder is protected after treatment. Methods Eighteen rabbits were divided into three groups. Sham-operated group (group 1) included 6 rabbits. Twelve rabbits were partially obstructed for 70 days. Six of these 12 rabbits not receiving any treatment constituted obstructed group (group 2). The remaining six rabbits received 2 mg/kg/day aspirin (group 3). One rabbit in each group was evaluated on 1st, 7th, 14th, 28th, 42nd, and 70th days following obstructive surgery. After scarification, the percentage of collagenous area and concentrations of PGE2 and PGF2-alpha were measured. Contractile responses to field stimulation (EFS), carbachol, and potassium chloride (KCl) were determined. Results Wet tissue PGE2 and PGF2-alpha levels were higher in obstructed group than the other groups. Aspirin decreased the percentage of collagenous area in group 3 compared to the group 2, but this difference was not statistically significant. The strips from aspirin groups resulted in better contractile response to cholinergic stimulation with KCl, but this difference was not statistically significant between the obstructed and aspirin groups. Similarly, carbachol did not elicit significantly greater concentration-dependent contraction in strips from obstructed group compared to those from aspirin groups. Maximum responses to EFS were not significant in aspirin group compared to those from obstructed group. Conclusions Intravesical aspirin may have protective effect on partially obstructed bladder.

What's known on the subject? and What does the study add? Urinary bladder tissue can be produced by several regenerative techniques although consistent regeneration remains elusive and no single protocol is superior to the others. Small intestinal submucosa has been used as substrate for regeneration in several models and allows for full-thickness bladder regeneration. Nanotechnology has been applied to impart specific physical and biological properties onto biological substrates. Nanoparticles composed of PLGA can be modified by the addition of hyaluronic acid and can be added to SIS. This modified SIS demonstrates a potential improvement in biological activity as suggested by more consistent smooth muscle regeneration in a canine model of bladder regeneration. This study demonstrates both the feasibilty and potential of synthetically-modified natural biomaterials. OBJECTIVE • To determine if hyaluronic acid (HA) can be incorporated into porcine small intestinal submucosa (SIS) through poly (lactide-co-glycolide-acid) (PLGA) nanoparticles to improve the consistency of the naturally derived biomaterial and promote bladder tissue regeneration. METHODS • Beagle dogs were subjected to 40% partial cystectomy followed by bladder augmentation with commercial SIS or HA-PLGA-modified SIS. • Urodynamic testing was performed before and after augmentation to assess bladder volume. • A scoring system was created to evaluate gross and histological presentations of regenerative bladders. RESULTS • All dogs showed full-thickness bladder regeneration. • Histological assessment showed improved smooth muscle regeneration in the HA-PLGA-modified SIS group. • For both groups of dogs, urodynamics and graft measurements showed an approximate 40% reduction in bladder capacity and graft size from pre-augmentation to post-regeneration measurements. • Application of the scoring system and statistical analysis failed to show a significant difference between the groups. CONCLUSIONS • SIS can be modified through the addition of HA-PLGA nanoparticles. The modified grafts showed evidence of improved smooth muscle regeneration on histological assessment, although this difference was not evident on a novel grading scale. • The volume loss and graft shrinkage experienced are consistent with previous models of SIS bladder regeneration at the 10-week time point. • Additional research into the delivery of HA and the long-term benefits of HA on bladder regeneration is needed to determine the full benefit of HA-PLGA-modified SIS. In addition, a more objective biochemical characterization will be needed to evaluate the quality of regeneration.

OBJECTIVE To examine the histological differences in the inflammatory response and regenerative outcomes of distal vs proximal porcine small intestinal submucosa (SIS) grafts in the rat bladder, as SIS from distal small intestine yields reliable and reproducible bladder regeneration, while SIS from proximal portions of small intestine does not provide similar results. MATERIALS AND METHODS In all, 30 Sprague-Dawley rats underwent hemi-cystectomy followed by anastomosis of a bladder patch of SIS prepared from either distal or proximal small intestine. After bladder harvest, immunohistochemistry was used to quantify mast cells, eosinophils, macrophages, and neutrophils (PMNs). Total cell count per unit area was compared across the time course in univariate and logistic regression modelling. RESULTS There were more eosinophils and mast cells in proximal SIS grafts, while there were more macrophages and PMNs in distal SIS grafts (all P

Objective To assess parental satisfaction with e-mail consultations and fetal outcomes after consultation for offspring with 45,X/46,XY mosaicism. Patients and methods A chart review was performed of prenatal and postnatal e-mail consultations concerning 45,X/46,XY mosaicism at our institution. Prenatally, mosaicism was detected by amniocentesis; postnatally by phenotype and subsequent genotyping. Parents e-mailed us for a second opinion after internet searches. Follow-up parental satisfaction was evaluated by e-mail. Results E-mail consultation occurred in six prenatal and eight postnatal cases. One of the eight postnatal cases had a prenatal diagnosis but without our second opinion. In 7/8 postnatal cases, abnormal neonatal phenotype was evaluated by genotyping. Termination of pregnancy was a consideration in all six prenatal consultations, although not discussed by us. One fetus was stillborn. Postnatal karyotype was mosaic in 11/13 surviving neonates. Phenotypes in surviving fetuses were normal male (2/13), hypospadias and an undescended testis or streak gonad (9/13), female with mild clitoral hypertrophy (1/13), and normal female (1/13). The stillborn fetus was noted only to have a penis. Conclusion All parents reported in follow up that e-mail consultations provided them with enhanced clinical information, allowing them to make better informed clinical decisions.

We reviewed our initial results with complete primary repair of exstrophy in regard to continence status and the need for subsequent continence procedures.We performed a retrospective review of our surgical records from 1996 to 2008 to identify all patients with bladder exstrophy managed at our center.Sixteen children were closed successfully. Six patients (37.5%) experienced complications: umbilical hernias in two, transient penopubic fistula in three, and subcoronal fistula due to meatal stenosis in one. Of the 12 males, seven (58.3%) were left with a hypospadias at the time of primary closure. Two (22.2%) children required a formal bladder neck reconstruction to achieve continence. Bladder augmentation and continent catheterizable stoma was performed in four cases (44.4%), and bladder neck injection in one case (11.1%). Bladder neck closure was also performed in another child following primary closure. Three of these children are continent and void spontaneously (33.3%). The remaining six require clean intermittent catheterization four to six times a day, resulting in four (44.4%) being continent. The number of continence procedures and mean number per patient were 15 and 1.66, respectively.Our early experience with this technique has been encouraging, with few major complications, a highly successful closure rate and a cosmetically normal result.

Objectives To present our long-term results with complete penile disassembly for epispadias repair. Methods We performed a retrospective review of our surgical records from 1996 to 2008. Group 1 included 12 patients who had undergone complete penile disassembly as a part of complete primary repair of bladder exstrophy, and group 2 included 9 patients with isolated epispadias. Results The mean follow-up after epispadias repair was 58.2 and 58.6 months for groups 1 and 2, respectively. At the last follow-up visit, 83.3% of group 1 and 100% of group 2 were completely dry or had dry intervals >4 hours. Of the 21 children, 7 (33.3%) experienced minor complications, 4 in group 1 and 3 in group 2. No ischemic changes of the glans penis or corporal bodies were observed in either group. Erectile function was preserved in all patients. Conclusions Complete penile disassembly technique can achieve total or near complete urinary continence, decreasing the morbidity of multiple procedures and potentially allowing children to achieve continence at an earlier age. Our experience, with a mean follow-up of nearly 5 years and an overall complication rate of 33.3%, is comparable to that of other published series.

We determined the rate of stone clearance in children following percutaneous nephrolithotomy, endoscopic assessment of residual stone and the judicious use of second look nephroscopy.We retrospectively reviewed the charts of all children undergoing percutaneous nephrolithotomy from 1996 to 2007. Cases were reviewed for pertinent details including preoperative and postoperative imaging, specifics of the procedure and followup. On completion of percutaneous nephrolithotomy the collecting system was assessed via combined nephrostogram and direct nephroscopy. If the collecting system could not be completely visualized or all stone fragments could not be cleared, the patient was referred for second look nephroscopy. Any residual stone present on initial followup imaging constituted a treatment failure.A total of 24 patients underwent percutaneous nephrolithotomy for 30 separate renal calculi. Mean patient age was 9.6 years, and mean stone burden was 2.53 cm. The success rate for percutaneous nephrolithotomy (inclusive of second look nephroscopy) was 87%. Of 30 cases 16 were managed by second look nephroscopy, with findings of residual fragments in all 16. Treatment failure was noted in 1 patient without second look nephroscopy and in 3 patients with second look nephroscopy. Of the 4 patients with treatment failure all were eventually rendered stone-free.Second look nephroscopy based on endoscopic findings during initial percutaneous nephrolithotomy is a reliable method of detecting and clearing residual stone fragments. Using such a protocol we achieved a high success rate of stone clearance in a population of patients with a significant stone burden.

OBJECTIVES Inhibin B reveals Sertoli cell activity. After our previous findings of an increase in inhibin B succeeding classic inguinal orchiopexy, we sought to determine the changes in endocrine parameters after scrotal orchiopexy in patients with cryptorchidism and to compare these findings with the results of classic orchiopexy. METHODS A total of 50 boys with an undescended testis, 32 unilateral and 18 bilateral, were included in the present study. Scrotal orchiopexy was performed in all of them. Before and 6 months after orchiopexy, the serum basal inhibin B and other serum hormonal levels were measured in all patients. RESULTS The mean serum basal inhibin B levels had significantly increased and the other reproductive hormonal levels had not changed at 6 months after successful scrotal orchiopexy in our 50 patients (P = 0.016). Within the subgroups, the increase in inhibin B levels was significant in only those 2-9 years old with a unilateral undescended testis. The increase in inhibin B in those 10-12 years old with unilateral or bilateral undescended testis resulted from the start of puberty. No significant difference was found in terms of an increase in inhibin B after classic and scrotal orchiopexy. CONCLUSIONS The measurement of inhibin B levels could be used as a follow-up parameter after orchiopexy. The serum inhibin B level increases after scrotal incision orchiopexy just as after classic inguinal orchiopexy. The increased level of inhibin B might indicate that the orchiopexy has been beneficial.

Splenogonadal fusion (SGF) is a rare congenital anomaly in boys and girls. It commonly presents as a testicular mass treated with an unnecessary orchiectomy. We present 3 cases of SGF diagnosed in adulthood and discuss the published literature focusing on several aspects of this rarity. These cases of SGF of both types presented with the usual complaints. In our first case, orchiectomy was performed since the left testis was hypoplastic and testicular neoplasm could not be ruled out. The testicles could be preserved in the latter 2 cases. The second case is the continuous-type SGF associated with contralateral testicular aplasia and, to our knowledge, this is the first reported case of continuous SGF associated with testicular aplasia. Knowledge of this entity may help prevent unnecessary orchiectomy.

The approach for the intravesical suspicious lesions or stones in the preadolescent children especially in boys is still a challenging problem. Open surgery, percutaneous suprapubic endoscopy or transurethral endoscopic approaches are the treatments of choice in children. However, there is a group in children between the ages of 10 and 12 years, which can be named as grey zone population; the length of the instruments is insufficient for transurethral intervention such as endoscopic stone extraction, transurethral bladder tumor resection especially for the lesion at the posterior bladder wall in this group. The aim of this study is to describe a new technique using laparoscopic instruments for percutaneous bladder stone and tumoral lesion and determines the efficacy of this procedure. Satisfactory results have been obtained in patients with these pathologies. In selected cases, operation time, urethral and mucosal damage, hospital stay, and cost can be decreased to a minimum with this simple technique.

Overactive bladder syndrome (OAB) and dysfunctional voiding (DV) are subgroups of lower urinary tract dysfunction (LUTD). Standard urotherapy is the first-line treatment option of OAB in children.The aim was to investigate the use of biofeedback as a first-line treatment option in OAB refractory to standard urotherapy, and determine the factors affecting efficacy.Between 2005 and 2015, we retrospectively analyzed a total of 136 hospital records of children with OAB who had not previously used any anticholinergics and were refractory to standard urotherapy. Patients with urgency and/or urge incontinence and/or making holding maneuvers to suppress urgency were defined as having OAB symptoms, and resolution of these complaints was defined as successful biofeedback therapy.Seventy-three of 136 OAB patients' urgency recovered by biofeedback therapy with the success rate of 53% (p0.001). Sixty-two of 101 patients with holding maneuvers (success rate 61%) (p0.001), 70 of 101 patients with urgency incontinence (success rate 69%) (p0.001), 76 of 114 patients with daytime incontinence (success rate 66%) (p = 0.023), 87 of 97 patients with enuresis (success rate 89%) (p = 0.009), and 27 of 39 patients with dysuria (success rate 69%) (p = 0.007) recovered from their symptoms significantly. The mean lower urinary tract symptom score (LUTSS) was 16.38 and 8.18 before and after biofeedback therapies, respectively (p0.001) (Table). Patients without holding maneuvers (p = 0.045), daytime incontinence (p = 0.030), and enuresis (p = 0.045) had better recovery compared to the opposites.Biofeedback can be thought of as the first-line treatment option when standard urotherapy fails in children with OAB.

Background: Fournier’s gangrene (FG) is an extensive fulminant infection of the genitals, perineum or the abdominal wall. The aim of this study is to share our experience with the management of this difficult infectious disease. Methods: Thirty-three male patients were admitted to our clinic with the diagnosis of FG between February 1988 and December 2003. The patient’s age, etiology and predisposing factors, microbiological findings, duration of hospital stay, treatment, and outcome were analyzed. The patients were divided into two groups. The first 21 patients (Group I) were treated with broad-spectrum triple antimicrobial therapy, broad debridement, exhaustive cleaning, and then they underwent split-thickness skin grafts or delayed closure as needed. The other 12 patients (Group II) were treated with unprocessed honey (20–50 mL daily) and broad-spectrum triple antimicrobial therapy without debridement. Their wounds were cleaned with saline and then dressed with topical unprocessed honey. The wounds were inspected daily and the honey was reapplied after cleaning with normal saline. Then, the patients’ scrotum and penis were covered with their own new scrotal skin. Results: The mean age of the patients was 53.9 ± 9.56 years (range = 23–71). The source of the gangrene was urinary in 23 patients, cutaneous in seven patients, and perirectal in three patients. The predisposing factors included diabetes mellitus for 11 patients, alcoholism for 10 patients, malnutrition for nine patients, and medical immunosuppression (chemotherapy, steroids, malignancy) for three patients. The mean duration of hospital stay was 41 ± 10.459 (range = 14–54) days. Two patients in Group I died from severe sepsis. The clinical and cosmetic results were better in Group II than Group I. Conclusions: Necrotizing fasciitis of the perineum and genitalia is a severe condition with a high morbidity and mortality. Traditionally, good management is based on aggressive debridement, broad-spectrum antibiotics, and intensive supportive care but unprocessed honey might revolutionize the treatment of this dreadful disease by reducing its cost, morbidity, and mortality.

We assessed the impact of intermittent tamsulosin treatment on abnormal ejaculation.This prospective study was performed between January 2001 and December 2004. It included 405 patients who were at least 50 years old with lower urinary tract symptoms. This study was divided into 2 phases. In phase 1 patients received a 0.4 mg tamsulosin capsule daily after breakfast for at least 3 months. The second phase of this study was performed in the 30 patients with abnormal ejaculation. In this phase these patients received 0.4 mg tamsulosin once daily every other day. Patients were assessed at study entry and at study week 6.Abnormal ejaculation was reported as retrograde ejaculation by 18 patients, as decreased volume by 7 and as absent ejaculate by 5. Ejaculatory function recovered during intermittent tamsulosin treatment in 12 patients with retrograde ejaculation and in 7 with decreased volume or absent ejaculate. As a result, 19 of 30 patients (63.3%) with abnormal ejaculation recovered. A significant improvement in retrograde ejaculation was found after intermittent tamsulosin treatment (p = 0.02). Although there were improvements in decreased volume or absent ejaculate at week 6 of intermittent treatment, these differences were not statistically significant (p = 0.42 and 0.61, respectively).The results of the current study, which to our knowledge is the first report of the effect of intermittent tamsulosin treatment on abnormal ejaculation, show that this treatment modality is well tolerated and provides comparable improvements for abnormal ejaculation.

We studied the effects of biofeedback treatment on voiding and urodynamic parameters in children with voiding dysfunction.We prospectively studied 188 children between June 1998 and November 2003. Biofeedback was performed with a urodynamics processor that enables simultaneous recording of urine flow and electromyography, and visual display of flow/electromyography activity. At the beginning of the study this treatment was performed once weekly. After patients understood the concept and performed homework regularly sessions were scheduled at 3 to 4-week intervals and continued for 6 months. All children were evaluated at 6 months and again at 2 years after completing biofeedback training.The number of the children completing biofeedback was 168 (89.4%). Improvement was obtained in all parameters, ranging from 59.2% to 87.8% at 6 months. Maximum improvement was acquired with flattened voiding in 65 of 74 children (87.8%), whereas the least improvement was acquired with daytime wetting in 58 of 98 children (59.2%). These improvements continued at 2-year followup, and ranged from 53.1% to 87.3%. While the rate of improvement for nocturnal enuresis, staccato voiding, detrusor-sphincter dyssynergia, vesicoureteral reflux and urinary tract infection had increased, the remaining parameters had decreased at 2-year followup.Biofeedback training is a simple, effective and well tolerated treatment modality in children for various parameters resulting from bladder dysfunction. Motivation and willingness to participate in biofeedback treatment are important selection criteria.

We studied the effect of varicocele ligation on Kruger strict morphology criteria and semen parameters in patients with infertility.A total of 90 patients diagnosed with varicoceles and a normal morphological sperm ratio of less than 14% were evaluated before and 6 months after varicocelectomy. Preoperatively and postoperatively sperm density, motility and morphology using Kruger strict criteria were analyzed. The Wilcoxon test was used to measure levels of statistical significance in all analyses.Significant improvement in sperm concentration and motility was evident after varicocele ligation (p0.0002 and0.0001, respectively). Using the Kruger classification sperm morphology evaluation revealed a significant increase in the percent of normal forms, and of forms with head and acrosome defects (p0.0001,0.0014 and0.0028, respectively). There were no concomitant changes in strict morphology in forms with mid piece and tail defects or immature forms (p0.05). Of the 90 patients 18 (20%) achieved a successful full-term pregnancy, including 14 via natural cycle intercourse and 4 by intrauterine insemination.Surgical correction of varicocele was associated with significant improvement in density, motility and sperm morphology evaluated using the Kruger classification.

To find answers about preventing the colonic mucosal regrowth after seromuscular enterocystoplasty and the dissection pane, we performed an experimental study in dogs. We also report our experience with mucosal regrowth and bladder function after augmentation colocystoplasty.This study comprised 10 adult healthy female mongrel dogs. We performed this animal experiment in 2 stages. At stage 1 we constructed a low capacity bladder. Stage 2 was performed 6 months after stage 1. At the end of detrusorectomy a 15 cm. segment of sigmoid colon was detubularized. The animals were randomly divided into 2 groups. In the 5 group 1 dogs de-epithelialization was performed with needle point cautery at a low cut setting, and the mucosa, muscularis mucosa and submucosa were resected, leaving the fibers of the muscularis externa exposed. In the 5 group 2 dogs de-epithelialization was performed by the peeling technique, in which the dissection plane was developed between the mucosa and muscularis mucosa, and the muscularis mucosa and submucosa remained on the colonic muscle. The de-epithelialized patch of bowel was shaped as a cup patch and anastomosed to the edges of the detrusor muscle over the bulging urothelium. The animals were sacrificed at 12 months of followup. All bladders were inspected macroscopically for regrowth of the colonic mucosa. Multiple sections of the augmentation patches were obtained and processed routinely for histological evaluation to determine what happened to the urothelium.We noted good urodynamic results in all dogs and there was no statistical difference in the groups in regard to bladder capacity. Mucosal regrowth did not develop in either group.When dissection is performed successfully whether or not the submucosa is removed, there is no observed regrowth or loss of bladder capacity in either technique.

To discuss the diagnosis and treatment of ejaculatory duct obstruction in male infertility.Twenty-four males were treated for ejaculatory duct obstruction between 1994 and 1998 in our clinic. Patients' age varied between 20 and 40 (mean=29). Ejaculatory duct obstruction was considered in patients with low to normal ejaculate volume, azoospermia or oligospermia, decreased motility, normal serum gonadotropin and testosterone levels, absent or low fructose in the ejaculate and evidence of obstruction on transrectal ultrasonography. The definitive diagnosis was made by the absence of efflux of methylene blue injected through the vas during cytoscopy. All the patients were subjected to transurethral resection of ejaculatory ducts and spermograms before and 3 months after resection were compared.Before transurethral resection mean sperm count was 1.66x10(6)/ml compared to 25.4x10(6)/ml postoperatively. The difference was statistically significant (p=0.001). After the operation, 58.3% of the cases had improvement in sperm motility, and 62.5% had increased ejaculate volume. No significant complications occurred, and in only 1 (4.17%) patient, there was persistent hematuria. After a mean follow-up period of 9 (6-18) months, 6 (25%) pregnancies were noted.Although transurethral resection is an effective method for the treatment of ejaculatory duct obstruction, the pregnancy rate is low, which could be related to the hazardous effects of urinary reflux into ejaculatory ducts or functional abnormalities of seminal vesicles.

A 21-y-old man applied to hospital with a complaint of erectile dysfunction, which started soon after a gunshot injury. The entry of the bullet was at the middle right gluteal region without any exit hole. A pelvic X-ray revealed the bullet and the scattered particles. On penile Doppler ultrasonography, the peak systolic velocities (PCV) of the right and the left cavernosal arteries were 19 and 29 cm/s, respectively. Pudendal angiography revealed poor visualization of the right pudendal artery below the level of the bullet. The patient underwent a right-sided Alcock's canal releasing surgery. After the operation, on control penile Doppler ultrasonography, PCV on the right and the left cavernosal arteries were 53 and 35 cm/s, respectively. The control angiography revealed a normal right pudendal artery. The patient was fully potent 2 y after the operation. Not only the entrapment of pudendal nerve but also the pudendal artery may cause Pudendal canal syndrome. A gunshot injury may cause such a condition due to the reaction caused by the bullet. Pudendal canal decompression is a simple and effective treatment for pudendal canal syndrome.

Objectives To evaluate prospectively the success of scrotal incision orchiopexy (Bianchi technique) with or without inguinal hernia in patients with an undescended testis within the inguinal canal or beyond the external inguinal ring. Methods A total of 72 orchiopexies were performed in 56 patients with a primary undescended testis. The testicular position and size were assessed again at 1 year of follow-up. Results A total of 56 patients had bilateral (n = 14), right (n = 26), and left (n = 18) primary undescended testes. Scrotal orchiopexy was attempted in 72 testes and was successful in 68; the remaining 4 patients required conversion to traditional inguinal orchiopexy because of inadequate mobilization. In 34 children (43 testes), the testis was distal to the external inguinal ring (group 1). Scrotal orchiopexy was performed successfully in 42 testes in this group, and only 1 patient required conversion to a traditional inguinal incision. The average operating time was 18 minutes. In 22 children (29 testes), the testis was located within the inguinal canal (group 2); 3 cases required conversion to traditional inguinal orchiopexy. The average operative time was 25 minutes in group 2. All patients had satisfactory scrotal placement with at least one follow-up examination. Conclusions A scrotal incision for a palpable primary testis is well tolerated, cosmetically pleasing, and associated with a short operative time.

We describe a nephrogenic adenoma of the bladder in a 14-year-old girl with Turner's syndrome. The patient also had a past history of urological surgery for vesicoureteral reflux. In this case, the multifocal lesions were successfully treated by transurethral resection.

Summary Introduction Dysfunctional voiding (DV) occurs in neurologically normal children who are not able to establish brain control on detrusor muscle contractions (DMCs). It is also reported to be the result of incorrect voiding habits during toilet training. Children contract pelvic floor muscles (PFMs) to suppress DMC and DV begins. Urinary nerve growth factor (uNGF) is necessary for the synthesis and regulation of neurotransmitters, development of dorsal root ganglia (sensory neurons), and development of sympathetic cells during embryonic and post-natal life. uNGF has also a role in the intracellular signal transduction in nerve cells towards the target organ. To our knowledge, no study has investigated the association between uNGF, biofeedback treatment and DV in children. Objectives The aim was to examine the potential effect of uNGF in the assessment of the effectiveness of biofeedback success in children with lower urinary tract disorders. Study design Fifty-two children with the suspicion of DV and 48 children from a primary school reporting no urinary complaints were enrolled in this study from October 2010 to April 2013 in the Urology Department. uNGF levels were compared. Results The mean uNGF/creatinine (Cr) level was 0.23 ± 0.26 in the control group and 0.96 ± 0.88 in the DV group (p Discussion To our knowledge this study is the first to show the correlations between uNGF levels and biofeedback therapy in children with DV. Tissue NGF in 12 patients with overactive bladder (OAB)/detrusor overactivity and 15 healthy women was previously compared and it was suggested that there was no correlation between bladder tissue NGF and OAB. uNGF levels in the bladder in patients with interstitial cystitis and idiopathic sensorial urgency were evaluated previously, and uNGF levels reported. Similar to these reports, most of the previous studies handled uNGF in patients with diseases such as interstitial cystitis, OAB, urinary tract infections, urolithiasis, spinal cord injury, and prostate cancer, and found significantly higher uNGF levels. These studies were generally in adults. A previous study about uNGF comprised 40 children with OAB, in contrast to other studies. According to this study, 40 children diagnosed with OAB were administered anti-muscarinic therapy (oxybutynin 0.3–0.5 mg/kg/day). It was reported that uNGF/Cr levels of the OAB group were higher than control group. In the current study, we evaluated the uNGF difference in DV and the effect of biofeedback treatment on uNGF levels. Conclusions uNGF levels were higher in children with DV and decreased after biofeedback therapy. uNGF levels could be used for the diagnosis and the assessment of biofeedback success in these children.

The main objectives of this retrospective cohort study were to evaluate reproductive endocrine and semen profiles before and after simple orchiectomy in patients with unilateral postpubertal cryptorchidism and to investigate the relationship between hormone levels and histopathology of the removed testis. We evaluated 40 adult males who were admitted to our clinic, between 2001 and 2007, with unilateral undescended testis. Right orchiectomy was performed in 27 patients and left orchiectomy in 13. Semen analysis, serum inhibin B, follicle-stimulating hormone (FSH), luteinizing hormone (LH), and testosterone levels were examined in before and 3 months after orchiectomy. Orchiectomy materials were evaluated histopathologically. Semen parameters, as well as testosterone and LH levels, did not change in any histopathological subgroups in the postoperative follow-up. In patients with maturation arrest, mean serum inhibin B level statistically significantly decreased from 160.9 to 83.5 pg/ml, and mean FSH level significantly increased from 4.8 to 7.6 mIU/ml after orchiectomy (p value, 0.008 and 0.008, respectively). Though, the levels were still within the normal range of the two hormones. Simple orchiectomy does not have any effect on semen parameters and testosterone level in patients with postpubertal cryptorchidism. The change in inhibin B and FSH levels after orchiectomy in patients with maturation arrest is not clinically significant.

Urinary tract infection (UTI) is the most commonly diagnosed bacterial infection of childhood, and has a significant healthcare impact. Renal parenchymal infection and scarring are well-established complications of UTI in children and can lead to renal insufficiency, hypertension and renal failure. Although frequently encountered and well researched, diagnosis and management of UTI continue to be a controversial issue with many challenges for the clinician. The evolving state of knowledge about pediatric UTI leaves many questions and controversies. The goal of this chapter is to provide an up-to-date summary of the literature with particular attention to practical questions about diagnosis and management for the clinician. This chapter reviews also recent evidence regarding the epidemiology and evaluation of children with UTI.

reflexic neurogenic bladder with DSD (n 16) was markedly decreased compared with other types of neurogenic bladder. After oxybutynine treatment, bladder compliance was improved in all neurogenic bladder types (Table 1). The renal cortical lesion was aggravated in 3 children (18.8%) of the i®areflexia with high leak pressurei type, 1 (5.0%) of the i®hyperreflexia with DSDi type, and 2 (7.1%) of the i®hyperreflexia without DSDi type (Figure 1). CONCLUSIONS: Oral oxybutynin chloride treatment markedly improved the maximum cystometric capacity in all neurogenic bladder types although increases in maximum cystometric capacity/ estimated bladder capacity were limited. Patients with low compliance, areflexic neurogenic bladder with high leak pressure requires specific attention as this type has worse detrusor compliance.

Objectives To evaluate the effect of biofeedback therapy on the residual urine volume in children with dysfunctional voiding. Methods This prospective study was conducted in children with dysfunctional voiding associated with abnormal postvoid residual urine (PVR) from June 2002 to 2007. The children were divided randomly into 2 groups. Group 1 was treated with standard urotherapy combined with biofeedback therapy and group 2 was treated with only standard urotherapy. The outcomes of uroflow-electromyography pattern, urinary tract infection (UTI), and PVR were recorded before and at the end of sixth month of treatment. Results A total of 94 patients were enrolled in this study. Groups 1 and 2 consisted of 62 and 32 patients, respectively. The voiding pattern became normal in 80.6% (50/62) and 56.2% (18/32) of patients in groups 1 and 2, respectively. The PVR resolved in 40 of 62 (64.5%) patients in group 1 and in 11 of 32 (34.4%) children in group 2. Before the treatment, UTI was noted in 22.5% of patients (14/62) in group 1 and 21.8% of patients (7/32) in group 2. After the treatment, UTI was observed in 3.2% of patients (2/62) and in 9.3% (3/32) of patients in groups 1 and 2, respectively. Although both treatment modalities changed the voiding pattern, rate of febrile UTI, and PVR positively, these outcomes were better in a combination group. Conclusions The combination of standard urotherapy with the biofeedback therapy improved the results significantly.

Objectives To assess our experience with salvage continence procedures in patients with bladder exstrophy. Methods We retrospectively reviewed our surgical records of patients with bladder exstrophy who had undergone failed modern staged repair elsewhere and underwent salvage continence operations at our institute from 1996 to 2008. Results A total of 16 patients had undergone salvage continence operations. Bladder augmentation was performed in 11 patients (68.8%); 14 children (87.5%) received a continent, catheterizable stoma. In 6 children (37.5%) bladder neck injections were done. Three patients (18.8%) underwent bladder neck closure combined with other reconstructive procedures. A total of 49 continence procedures were performed, with an average of 3.06 per patient. We included all 16 children >5 years. After these operations, 13 of 16 (81.3%) became continent. Two children were able to void spontaneously and were dry day and night (12.5%). Of the remaining 14 patients, all of whom used clean intermittent catheterization, 11 (68.7%) were continent during the day and night with augmentation and/or a catheterizable stoma. Three patients were incontinent (18.7%). Conclusions Although the need to perform salvage continence procedures after failed bladder modern staged repair is high, when patients are appropriately selected, continence can be achieved eventually.

Shockwave lithotripsy (SWL) is the treatment of choice for most renal calculi because it is highly effective and relatively noninvasive. Although complications of SWL are relatively few, one that occurs more frequently is perirenal hematoma, usually diagnosed by radiologic procedures. We present an interesting case of scrotal ecchymosis as an unusual presentation of perirenal hematoma causing ipsilateral spermatic-vein thrombosis after SWL for a left renal stone. To our knowledge, this condition has not been reported previously.
