BACKGROUND: Creatinine elevation and changes in urinalyse parameters may be seen due to acute kidney injury during COVID-19. In the present study, we aimed to investigate the changes in urinalysis of COVID-19 patients with normal kidney function. METHODS: The data of COVID-19 patients with normal renal functions were retrospectively analyzed. Urinalysis parameters of these patients were recorded. The patients were divided into three groups as mild, moderate and severe with respect to the clinical course of the disease. It was examined whether the urine analysis values in the groups were different from normal reference values and whether these values were different between the groups. In addition, possible relationship between the urinalysis parameters and the clinical severity of the disease was investigated. RESULTS: There are three groups; mild (n:40), moderate (n:38) and severe (n:42). Mean age were significantly higher in the severe group, while gender distribution of the groups was similar. (p=0.033) (p=0.091) Creatinine values of all patients were normal. There were 6.7% glucose positivity, 13.4% protein positivity, 5.8% urobilinogen positivity and 7.5% ketone positivity in urine dipstick analysis and these changes were all significantly higher than the reference values.

Demirelli, Erhan/0000-0002-0187-2156 WOS: 000514117700001 PubMed: 32072659 Aortic stiffness increases in patients with erectile dysfunction (ED) but it is not known whether aortic stiffness affects the degree of ED. In the present study, we aimed to determine whether there is any relationship between aortic stiffness and the severity of ED. Patients with ED were divided into 3 groups according to the International Index of Erectile Function (IIEF) scores. Mild ED was named as group 1, moderate ED as group 2 and severe ED as group 3. The values of fasting blood glucose (FBG), serum lipid values, total testosterone (T. tes), and free testosterone (F tes) were recorded. Aortic stiffness was determined by pulse wave velocity (PWV) and augmentation index (AIX) measurements. The mean or median values of the laboratory parameters among the groups were similar (p > .05). No statistical difference was found between the groups in terms of AIX value (p = .386). Mean PWV values were calculated as 7.26, 8.30 and 8.78 in group 1, group 2 and group 3 respectively. PWV values were significantly different between groups (p < .0001). PWV values were found to be increased with increasing severity of erectile dysfunction.

WOS: 000519233300001 PubMed: 31586281 Purpose We aimed at comparing the success and complications of early semirigid ureteroscopy (URS) and elective URS in ureteral calculi with renal colic that do not respond to analgesics. Methods We retrospectively analyzed the data of 690 patients with obstructive ureteral stones who underwent URS with stone retrieval. 247 patients who underwent early URS within the first 12 h were classified as group I and 443 patients who underwent elective URS as group II. Both groups were compared in terms of age, sex, creatinine, eGFR, stone size, laterality, location and number of stones, type of lithotriptor, presence of hydronephrosis and success and complication rates. Results The mean age of the patients was 50.4 (18-89 years) (p > 0.05). There was no statistically significant difference between the groups in terms of age, eGFR, side, presence of hydronephrosis, fever, mucosal damage, stone migration, perforated ureter, ureteral avulsion, ureteral stent insertion at the end of the surgery and sepsis (p > 0.05). Both groups had male dominance (p > 0.05). Creatinine was significantly lower in Group I (p < 0.05). The mean stone size was also significantly lower in Group I ( p < 0.05). Middle and proximal ureteral calculi were more common in Group II (p < 0.05). Multiple stones were higher in Group II (p < 0.05). The dominant type of lithotriptor used was pneumatic in Group I and laser in Group II (p < 0.05). Stone-free rates (SFRs) were higher in Group I (98% vs 90% in the first month) (p < 0.05). Postoperative hematuria and infection were more common in Group II (p < 0.05). Conclusions In selected cases, early ureteroscopy is an effective and safe method for distal ureteral calculi smaller than 10 mm that are painful and resistant to analgesic treatment.

WOS: 000454525500003 Objective: To investigate the potential effect of smoking on pathological staging in clinically low-risk patients. Subjects and methods: Data of 59 patients who were diagnosed with a bladder tumor for the first time and had a single lesion radiologically and endoscopically smaller than 3 cm were investigated, retrospectively. A total of 33 patients who currently smoke or smoked were classified as Group I and 26 patients who did not ever smoke were classified as Group II. Pathological diagnoses of the patients in both groups were compared. Results: A total of 9 patients (27.3%) in Group I and 18 patients (69.2%) in Group II had Ta disease (p < 0.05). Moreover, 19 patients (57.6%) in Group I and 5 patients (19.2%) in Group II had stage T1 disease (p < 0.05). The number of patients with low grade (LG) tumor were 8 (24.2%) and 19 (73.1%) in Group I and in Group II, respectively (p < 0.05). The number of patients with high grade (HG) tumor were 25 (75.8%) and 7 (26.9%) in Group I and in Group II, respectively (p < 0.05). Ta high grade (TaHG) was detected in 9 (27.3%) patients in Group I. In contrast, no patients in Group II had Ta HG disease (p < 0.05). The number of patients with T1 high grade (T1HG) was 17 (51.5%) in Group I and 2 (7.69%) in Group II (p < 0.05). Conclusion: Smoking seems to associate with pathologically worse stage and grade in patients with primary, single

WOS: 000474443200012 PubMed: 30201079 Objective: We compared the number of interstitial cells (ICs), nerves, presence of fibrosis and inflammation at the level of full-thickness human ureteropelvic junction (UPJ) tissues obtained from normal subjects, and patients with UPJ obstruction with and without crossing vessels. Material and methods: Normal UPJ tissues (n=12) histopathologically confirmed to be without tumor involvement were obtained from subjects who underwent radical nephrectomy for kidney mass. Additional UPJ tissues were obtained from patients who underwent pyeloplasty due to UPJ obstruction. Crossing vessel was identified in 17 patients. In 57 patients, no crossing-vessel was noted. ICs were stained immunohistochemically with anti-human CD117 (c-kit) antibody. Neural tissue was stained with S-100. The numbers of ICs and neurons were compared between the groups: controls with normal UPJ (Group I), Ureteropelvic junction obtruction (UPJO) with crossing vessel (Group II) and UPJ obstruction without crossing vessel (Group III). Groups were also compared in terms of the presence of fibrosis and inflammation. Results: The mean age of total population included in the study was 30.5 +/- 18.5 years. No significant differences were detected between the three groups regarding mean and median numbers of ICs at the level of UPJ (lamina propria and muscle layer) and mean and median numbers of neurons at the level of lamina propria (p>0.05). Likewise, no significant differences were detected between the three groups regarding the presence of fibrosis and inflammation (p>0.05). Conclusion: Number of ICs, neurons, presence of fibrosis and inflammation seem to be similar in the intact UPJ and UPJ with obstruction with and without crossing vessel. Cellular function rather than the number ICs might play a role that warrants further research.

Introduction: We investigated the potential effect of smoking on pathological staging in clinically low-risk patients. Material-Methods: Data of 59 patients who were diagnosed with a bladder tumor for the first time and had a single lesion radiologically and endoscopically smaller than 3 cm were investigated, retrospectively. A total of 33 patients who currently smoke or smoked were classified as ever smokers group and 26 patients who did not ever smoke were classified as never smokers group. Pathological diagnoses of the patients in both groups were compared. Results: A total of 9 patients (27.3%) in ever smokers group and 18 patients (69.2%) in never smokers group had Ta disease (p

We investigated the effect of cigarette smoking on pathological staging in clinically low-risk patients. Data of 59 patients who were diagnosed with bladder tumor for the first time and had a single lesion radiologically and endoscopically smaller than 3 cm were investigated retrospectively. 33 patients who smoked were classified as Group I, and 26 patients who did not smoke were classified as Group II. Pathological diagnoses of the patients in both groups were compared. The mean age of the patients were 64.8 (20–86) years. In Group II, 5 (19.2%) were female and 21 (80.8%) were male (p < 0.05). Nine patients (27.3%) in Group I and 18 patients (69.2%) in Group II had Ta disease (p < 0.05). Nineteen patients (57.6%) in Group I and 5 patients (19.2%) in Group II had T1 disease (p < 0.05). The number of patients with low grade (LG) tumor were 8 (24.2%) and 19 (73.1%) in Group I and in Group II, respectively (p < 0.05). The number of patients with high grade(HG) tumor were 25 (75.8%) and 7 (26.9%) in Group I and in Group II, respectively (p < 0.05). TaHG was detected in 9 (27.3%) patients in Group I. In contrast, no patients in Group II had TaHG disease (p < 0.05). The number of patients with T1HG was 17(51.5%) patients in Group I and 2 (7.69%) patients in Group II (p < 0.05). Smoking is associated with pathologically HG and stage in patients with first time bladder tumor which is single and smaller than 3 cm.

To evaluate the treatment alternatives of total avulsion of the ureter from both ends including ureteropelvic junction (UPJ) and ureterovesical junction (UVJ). Total ureteral avulsion on both ends of the ureter was examined in 4 cases performing ureteroscopy. In two male patients of the four cases, avulsion was noticed intraoperatively and ureteral re-anastomosis at UPJ and re-implantation at UVJ were performed immediately. Boari flap was performed for one female patient immediately and for the other female patient who was referred from another hospital after the ureteroscopy, 4 days later. One patient who had ureteral re-implantation was followed with 3-month intervals by ultrasonography and abdominal X-ray. At the end of 1 year, it was determined that kidney parenchyma was normal and the patient had kidney and upper ureteral stones. Percutaneous nephrolithotomy was performed, and the patient was stone-free at the end of the operation. Two years after the surgery, both kidneys were normal. This is the only case who had a successful ureteral re-implantation in literature. The other patient turned up a year later for routine checks after the ureteral stent was removed. Then, hydronephrosis and renal atrophy were detected. The patient did not accept nephrectomy or any other intervention and he was lost to follow-up. Boari flap procedure was performed after UPJ repair for the other two female patients. Their kidneys were both normal 3 months after the operation. In case of ureteral avulsion from both ends of the ureter in the male patients, as bladder capacity is not enough for a Boari flap, proximal anastomosis and distal re-implantation could be a good choice for the management of this untoward event. This new approach also saves time for reconstructive treatments if necessary. If bladder capacity is enough to reach UPJ, Boari flap could be a good choice in female patients.

WOS: 000410005000014 PubMed: 28861302 Objective: We aimed to investigate factors related to early postoperative pain after retrograde intrarenal surgery (RIRS). Material and methods: A prospective data analysis of 250 patients who underwent RIRS due to kidney stones was performed. Postoperative pain was evaluated in all patients by using visual analogue scale (VAS). Patients with severe pain (VAS score >= 7) were separated and included in Group I (n=46). While patients without pain or with insignificant pain were included in Group II (n=204). The impact of patient-related (age, gender, renal anomalies, shock wave lithotripsy history, preoperative hydronephrosis) stone-related (stone number, side, size, location and opacity) and operation-related (preoperative and postoperative ureteral Jstenting, ureteral injury, postoperative bleeding and fever, stone-free rates, size of access sheath, and sheath indwelling time) factors on early stage postoperative pain (if any) were investigated. Results: Female gender increased the risk for pain 3.6-fold (p

To present our experience with retrograde intrarenal surgery (RIRS) for managing renal stones in patients with spinal deformities.We retrospectively reviewed the records of eight patients with congenital scoliosis (n=6), ankylosing spondylitis (n=1), or spina bifida (n=1) who had undergone RIRS for renal stones. Stone-free status was determined by CT 30 days after the procedure and was defined as the absence of stones in the kidney or residual fragments ≤ 1 mm.Mean patient age was 32.5 years (8-51 years), and mean stone size was 15.8 mm (9-20 mm). The average operative time was 46.5 minutes (25-75 min), and postoperative hospital stay was 1.12 days (1-2 days). A stone-free status was obtained in six (75%) patients, and two patients were considered to have treatment failure. A Double-J stent was placed at the end of the procedure in five (62.5%) patients. Double- J stent discomfort was reported by one (20%) patient who was treated conservatively. No severe complications, either from anesthesia or the surgical procedure, were observed, and no blood transfusion was reported.The good clearance rate with a low incidence of complications shown by the present study has demonstrated that RIRS is a safe and effective procedure for renal stones in patients with spinal deformities.

Aim: To assess the diagnostic accuracy of PI-RADS v2.1 using multi-parametric magnetic resonance imaging (mpMRI) to detect prostate cancer (pCa) and comparison with transrectal biopsy/radical prostatectomy results.Material and Methods: Between June 2017 and April 2019, 124 patients who underwent mpMRI prior to transrectal biopsy/ radical prostatectomy were evaluated by a pathology results-blinded uroradiologist using PI-RADS v2.1 categories, retrospectively. PIRADS v2.1 category results were compared with transrectal biopsy/radical prostatectomy results. All clinical data were used in statistical analysis.Results: The sensitivity, specificity, positive predictive value, negative predictive value and accuracy values of mpMRI using PI-RADS v2.1 categorization were 96%, 44%, 73%, 88% and 75%, respectively. A significant correlation was observed between a high PI-RADS score and high pathological grade (p0.001). The inter observer agreement expressed as the ICC was 0.65 (95% CI: 0.33–0.84, p 0.001).Conclusions: The mpMRI, used in conjunction with PI-RADS v2.1, is a useful and promising imaging method in detection of pCa. Keywords: Prostate cancer; multiparametric MRI; PI-RADS; transrectal biopsy; radical prostatectomy.

The relationship between the results of penile duplex Doppler ultrasound (PDDU) and response to vardenafil was investigated in patients diagnosed with erectile dysfunction (ED). Data from 148 patients with ED were analyzed retrospectively. Patients who did not respond to therapy were classified in to Group I (n = 32), those who responded partially were classified into Group II (n = 40), and complete responders were classified into Group III (n = 76). Age, comorbidities, and vascular and penile pathologies were compared among the three groups. While diabetes mellitus (DM) and dyslipidemia positivity adversely affected the response to treatment, the presence of hypertension (HT), Peyronie’s disease and priapism increased the therapeutic response to the treatment (p < 0.05). Arterial insufficiency was present in 20 (30.3%), 25 (37.9%) and 21 (31.8%) of the patients in Group I, Group II and Group III, respectively (p = 0.001). Venous insufficiency was observed in three (14.3%) patients in Group I and in eight (85.7%) patients in Group III (p = 0.001). Arterial/venous insufficiency was seen in 9 (30%), 14 (46.7%) and 7 (23.3%) of the patients in Group I, Group II and Group III, respectively (p = 0.001). The response rate to treatment was highest in normal patients according to PDDU, followed by patients with venous insufficiency. In addition, it was found that DM decreased the response to treatment, whereas the response increased in cases with HT, priapism and Peyronie’s disease.

WOS: 000380066200025 PubMed: 27286123 Purpose: to investigate whether patients with lichen planus (LP) are really prone to urolithiasis or not. Patients and Methods: We performed a prospective analysis of 40 patients diagnosed with lichen planus (LP) (group I), and 40 volunteers did not have LP before (group II). Participants were all checked for urolithiasis by radiological investigations. Blood samples were analyzed for biochemistry parameters including calcium and uric acid. 24-h urine samples were analyzed to investigate oxalate, citrate calcium, uric acid, magnesium, sodium and creatinine. Results: Men/women ratio and mean age were similar between group I and II (p> 0.05). A presence or history of urolithiasis was detected in 8 (20%) and 2 (% 5) patients in group I and II, respectively (p< 0.05). Hypocitraturia was the most common anomaly with 35% (n: 14) in group I. The rate of hypocitraturia in group II was 12.5% (n: 5) and the difference was statistically significantly different (p= 0.036). In group I, hyperuricosuria and hyperoxaluria followed with rates of 27.5% (n: 11) and 25% (n: 10), respectively. The rate of hyperuricosuria and hyperoxaluria were both 5% (n: 2) in group II and the differences were significant (p< 0.05). Hyperuricemia was another important finding in the patients with LP. It was detected in 13 (32.5%) patients in group I and in 1 (2.5%) participant in group II (p= 0.001). Conclusion: According to our results, metabolic disorders of urolithiasis were highly detected in the patients with LP. However, similar to the etiology of LP, the exact reasons for these metabolic abnormalities in LP remain a mystery.

WOS: 000374234000009 PubMed: 26345399 The aim of this study was to investigate the frequency of nocturnal sperm emissions (NSE) in varicocele patients after varicocele surgery. A total of 127 patients, 96 varicocele (Group 1) and 31 patients with inguinal hernia (Group 2) were included in this study. Mean age, laterality of surgical procedures, spermiogram results, marital status, and postoperative serum hormone levels were noted for all patients. Two groups were compared in terms of Beck depression score (BDS) and anxiety scores (AS). The frequency of NSE and libido changes in the patients during 10 days postoperatively was evaluated. The number of the patients who had NSE and increased libido were significantly higher in the varicocelectomy group when compared with the control group. No significant difference was noted between the groups in terms of BDS, AS, and serum hormone levels. No association was reported between BDS, AS, and serum hormone levels and the presence of NSE in Group 1. The incidence of NSE was higher in younger men. Increased libido was significantly associated with NSE in Group 1. Cord dissection during surgery may be a factor on increased frequency of NSEs in varicocele patients.

Summary Objective In recent years, there has been increased incidence of urolithiasis in children. Changing nutritional patterns and sedentary lifestyles predispose to urolithiasis, as well as to the global rise in obesity. It has been established that the prevalence of high body mass index (BMI) is increasing in the pediatric population. The aim of the present study was to incorporate 24-h urine metabolic analysis results with BMI values to evaluate the tendency towards stone formation in children. Methods Eighty-four children were recruited to the study, stratified into three BMI categories as low, normal, or upper. All patients were evaluated with 24-h urine analysis results. Patients with a secondary cause of stone formation such as hyperparathyroidism, cystinuria, primary hyperoxaluria, inflammatory bowel disease, cystic fibrosis, history of prematurity and/or use of drug, recurrent urinary tract infection, and urinary tract anomaly were excluded. Additionally, it was ensured that none of the patients were taking specific medication or diet that could alter their acid-base metabolism and calcium, oxalate, and uric acid levels. Results Mean BMI of patients was 21.6 ± 2.9 kg/m 2 . LBMI was found in 52 (61.9%), N-BMI in 20 (23.8%), and U-BMI in 12 (14.3%) of the patients. No significant differences were present between the three groups for stone sizes and numbers. The patients' characteristics and 24-h urine parameters for BMI groups are presented in the Table. Discussion In the literature, several studies have focused on the relationship between obesity and pediatric urinary stone disease. However, only a few evaluated the urinary metabolic analysis in pediatric patients. We have encountered different results from mainly adult studies and some pediatric studies. Our study shows that U-BMI children are not under greater risk for urolithiasis than the other groups. An important portion of our study group was in the L-BMI group; nevertheless we cannot conclude that having a low BMI predisposes to urolithiasis based on the urinary metabolic evaluation as well as the stone sizes and numbers. The N-BMI group has increased risk factors for urolithiasis rather than the other groups, according to results of 24-h urine analysis. Conclusion The results of our study indicate that BMI itself could not be considered as a separate and definite risk factor for urolithiasis development in children. Although the mechanisms and causative factors for urinary stone formation are better defined in adults, further studies investigating these parameters in children are warranted. Table .

A 28-year old man presented with left flank pain and dysuria. Plain abdominal film and computed tomography showed a left giant ureteral stone measuring 11.5 cm causing ureteral obstruction and other stones 2.5 cm in size in the lower pole of ipsilateral kidney and 7 mm in size in distal part of right ureter. A left ureterolithotomy was performed and then a double J stent was inserted into the ureter. The patient was discharged from the hospital 4 days postoperatively with no complications. Stone analysis was consistent with magnesium ammonium phosphate and calcium oxalate. Underlying anatomic or metabolic abnormalities were not detected. One month after surgery, right ureteral stone passed spontaneously, left renal stone moved to distal ureter, and it was removed by ureterolithotomy. Control intravenous urography and cystography demonstrated unobstructed bilateral ureter and the absence of vesicoureteral reflux.

The purpose of the study was to investigate feasibility of retrograde intrarenal surgery (RIRS) in patients with isolated anomaly of kidney rotation with kidney stones. We retrospectively reviewed the medical records of patients who underwent RIRS due to kidney stones in three referral hospitals. Twenty-four patients who had kidney rotation were included in this study. The patients with horseshoe kidney or pelvic kidney were not included in the study. The patients were evaluated for final success 1 month after surgery. Success was defined as stone-free or fragment smaller than 3 mm. Mean age of patients was 39.5 years (1-71 years) and male/female ratio was 3:1. Mean stone size was 13.46 mm (5-30 mm). Twelve (50 %) patients had the operation on the right side and other 12 (50 %) patients had on the left side. Eighteen (75 %) patients were stone-free after single procedure. And stone-free rate increased to 83.3 % after additional treatment procedures. When we compared the successful and failed procedures, gender, stone side and size, preoperative hydronephrosis, access sheet usage, ureteral double-J stent insertion were not statistically significant in two groups. We did not confront major complication. RIRS seems to be an effective and safe treatment option for renal stones in patients with isolated anomaly of kidney rotation.

Objectives. To determine when emergent intervention for bleeding after percutaneous nephrolithotomy (PCNL) is required. Methods. We reviewed analysis data of 850 patients who had undergone PCNL in our center. Blood transfusion was needed for 60 (7%) patients during and/or after surgery. We routinely performed followup of the urine output per hour, blood pressure, and hemoglobin levels after PCNL. Five (0.6%) of them had severe bleeding that emergent intervention was needed. Results. The mean age of the 5 patients who had emergent surgery due to severe bleeding was 42.2 (19–56) years. Mean duration of surgery was 44.75 (25–65) minutes. Mean stone size was 27 (15–38) mm. Mean decrease of hemoglobin was 4.8 (3.4–5.8) ng/dL, and unit of transfused blood was 4.4 (3–6). Mean blood pH was 7.21. There were metabolic acidosis and anuria/oliguria in all these patients. One of 5 patients suffered from cardiopulmonary arrest because of massive bleeding four hours after the PCNL, and despite cardiac resuscitation, he died. Hemorrhaging was controlled by open surgery in the other 4 patients. Two patients experienced cardiac arrest during the open surgery but they responded to cardiac resuscitation. There were no metabolic asidosis and anuria/oliguria, and bleeding was managed only with blood transfusion for the other 55 patients. Conclusion. Severe bleeding after PCNL is rare and can be mortal. If metabolic asidosis and anuria/oliguria accompanied the drop of hemoglobin, emergent surgical intervention should be performed because vascular collapse may follow, and it may be too difficult to stabilise the patient.

Myiasis is the infestation of body tissues or organs by dipterous fly species and is often associated with poor hygiene. Urogenital myiasis is uncommon, and Psychoda albipennis-induced urogenital myiasis is very rare. In this article, we present a case of urinary myiasis caused by Psychoda albipennis. The patient claimed that he had observed more than 10 black-grayish-colored mobile particles in his urine. We identified them as the fourth stage of the moth fly Psychoda albipennis. The patient was a farmer and lived in Ankara, Turkey. He was treated with antibiotics, and there were no complications during or after treatment.

Objective: To evaluate the pathologic and clinic results of our large series of transrectal prostate biopsies in relation to Gleason score, age and PSA level. Materials and Methods: We reviewed the pathologic results of transrectal prostate biopsies performed because of high PSA levels and abnormal digital rectal examination findings between January 2008 and February 2012. Results: The pathologic result of 835 prostate biopsies was benign in 82.2% and malign in 17.8%. Furthermore in 3.7% high grade PIN (Prostatic Intraepitelial Neoplasia) or ASAP (Atypical Small Acinar Proliferation) was shown. In the interval of total PSA values between 4 and 10 ng/dl, that is thw so-called grey zone, cancer detection rate was 12.4%. There was a significant relationship between cancer detection and cancer stage at all high levels of PSA also in the grey zone. The most common Gleason score observed was 3 + 3 wirh a rate of 7.4% whereas the second most commonly observed scare was 3 + 4 with a rate of 2.5%. In the patients with abnormal digital rectal examination findings but normal PSA levels according to age the cancer detection rate was 8.7%, in patients with only high PSA levels the rate was 41.2% and in the patients with both high PSA levels and abnormal digital rectal examination findings. the rate was 49.3%. Conclusion: Our study underlines the relationship between age, PSA level and pathologic stage of prostate cancer and also the importance of digital rectal examination.
