The use of intravesical botulinum toxin-A (BTX-A) for the management of overactive bladder is rapidly increasing. In this research, we assess the efficacy of BTX-A vs solifenacin in men suffering from bladder outlet obstruction–over active bladder (BOO-OAB) managed with TURP.Methods: In this case–control study, 50 men with BOO-OAB randomized into two groups. The control group (A) underwent TURP and subsequently managed by solifenacin 5 mg daily, and the case group (B) underwent TURP and BTX-A injection in the bladder wall in the same session. Treatment success was the primary outcome and defined as post-injection improvement in the storage score of the International Prostate Symptom Score (IPSS) from baseline.Results: The IPSS, post-void residual volume, frequency, incomplete emptying, nocturia and urgency subscores considerably ameliorated after 12 weeks and 36 weeks for both groups, but it was more significant in the case arm. The quality of life (QoL) scores significantly improved after the treatments in both groups. Intervention group showed significant reductions regarding urgency incontinence compared with the solifenacin group at 12th and 36th weeks.Conclusion: BTX-A is an effective and well-tolerated treatment in patients with benign prostatic hyperplasia (BPH) who are candidates of TURP and simultaneously suffer from OAB symptoms.Keywords: anticholinergic drug, benign prostatic hyperplasia, botulinum toxin-A, over active bladder, solifenacin, TURP

The best management of incidental prostate cancer (iPCa) has been debated. The decision “treatment or no treatment” should be determined by predictors which accurately foretell PCa progression after transurethral resection of the prostate (TURP). The purpose of this study is to review the available data that can be useful in daily clinical judgment. Transrectal ultrasound prostate biopsy (TRUSBx) did not provide further Gleason score (GS) data in most patients diagnosed with iPCa. TRUSBX may be useful before active surveillance, but not in all following radical prostatectomy. The decision “treatment or no treatment” should be dependent on the expected chance of having residual cancer and clinical progression. Prostate-specific antigen (PSA) levels before and after TURP are good predictors of residual cancer after TURP. Pathological report of T0 is most likely seen in patients with low PSA density after TURP and indistinguishable lesion on multiparametric magnetic resonance imaging. The decision “treatment vs no treatment” is judged by life expectancy, tumor characteristic in the pathology report of TURP sample and PSA level following TURP. Active surveillance should be contemplated in patients with iPCa who have both prostate-specific antigen density ≤ 0.08 after TURP and indistinguishable cancer lesion on multiparametric magnetic resonance imaging. Patients who do not meet the criteria for active surveillance are candidates for radical prostatectomy or radiotherapy (RT). Radical prostatectomy could be peacefully done after TURP with somewhat greater morbidity. RT in patients who had a history of TURP could be safely done and is associated with acceptable quality of life.Keywords: incidental prostate cancer, prostate cancer, transurethral resection of the prostate, TURP

Amir-reza Abedi,1 Morteza Fallah-Karkan,2 Farzad Allameh,1 Arash Ranjbar,1 Afshin Shadmehr3 1Urology Department, Shohada-e-Tajrish Hospital, Shahid Beheshti University of Medical Sciences, Tehran, Iran; 2Urology Department, Shohada-e-Tajrish Hospital, Laser Application in Medical Sciences Research Center, Shahid Beheshti University of Medical Sciences, Tehran, Iran; 3Urology Department, Isfahan University of Medical Sciences, Isfahan, Iran Objective: Incidental prostate cancer (IPCa) is defined as a symptom-free cancer unexpectedly discovered upon microscopic examination of resected tissue. The aim of this study was to report the correlation between some specific clinical criteria in patients incidentally diagnosed with prostate cancer (PCa) during transurethral resection of the prostate (TURP) or open prostatectomy (OP) after clinically suspected benign prostatic hyperplasia.Patients and methods: This was a cross-sectional, retrospective study. Data were collected from Shohada-e-Tajrish Hospital database during November 2006 to October 2016. Four hundred and twenty three men suffering from symptomatic benign prostatic hyperplasia who underwent either TURP or OP that provided a prostate specimen were evaluated. The data analysis was performed using Pearson correlation test and independent t-test using SPSS version 20 software.Results: The mean age of subjects was 68.74±9.87 years old (45–93 years). The mean prostate specific antigen (PSA) level was 21.47±13.44 ng/mL (0.6–47.1 ng/mL). Results showed that 84 patients (19.9%) had PCa (40 patients who underwent TURP [12.6%] and 44 patients who underwent OP [40.7%] groups). Cut-off point of PSA for detecting IPCa was 3.8 ng/mL in our study, and this showed sensitivity, specificity, negative predictive value, and positive predictive value of 26.08%, 100%, 100%, and 29.79%, respectively. Twenty two patients with cancer had a positive family history for PCa; thus, a significant relationship between familial history of PCa and its occurrence was shown (p=0.0001).Conclusion: According to the results of this study, the cut-off point for PSA levels in detecting PCa was 3.8 ng/mL, which is similar to that reported by other studies. Familial history of PCa and PSA levels were two predictors in determining the PCa.

Introduction: Medical complaints are always the most challenging items in the scope of practice and have great difficulties for both the physician and the patient. Due to the need for comprehensive data for health planning of Guilan province And the importance of this research as factors in occupational safety and health practitioners, patients, re search in this area is necessary. Objective: Determining factors in a complaint to the Medical Council of Doctors in Gilan Province in the years 2005 to 2010 Materials an d Methods: In this cross-sectional study of 425 case s related to medical malpractice law suits stemming from the Medical Council of Guilan during the years 1385 to 1390 was carried out. Thus the plaintiffs checklist includes information such as age, sex, date of complaint, the complaint doctors information such as gender, field of practice, location of practice, Work Experience and the first instance and appeal preparation was completed. The data were entered into a statistical software SPSS18 and were analyzed using descriptive statistics. Results: Dentists had the most claims, followed by orthopedic surgeons, General Practitioners, General Surgeons and Gynecologists. Physicians were found innocent and guilty in 354 cases (83.3%) and 67 cases (15.7%) of cases, respectively. Al so, patients quit their claims in 4 case s. The most common cause s of complaints mentioned by patients, were medical error, complications of treatments and then, financial is sue s. Most cause s of proposing a claim were malpractice, treatment complications and financial is sue s. Conclusion: The data showed that most of the claims recorded were unfounded and consequently, respective physicians were not guilty. Therefore, knowledge of the patient' s physician, the patient is familiar with the methods of treatment and possible side effects and reduce the financial relationship between the physician and patient compliance in many case s can be prevented by a patient complaint.

Objectives: To review the current literature on the presence of COVID-19 virus in the urine of infected patients and to explore the clinical features that can predict the presence of COVID-19 in urine., Materials and Methods: A systematic review of published literature between 30th December 2019 and 21st June 2020 was conducted on Pubmed, Google Scholar, Ovid, Scopus, and ISI web of science. Studies investigating urinary viral shedding of COVID-19 in infected patients were included. Two reviewers selected relative studies and performed quality assessment of individual studies. Meta-analysis was performed on the pooled case reports and cohort with a sample size of ≥ 9., Results: Thirty-nine studies were finally included in the systematic review; 12 case reports, 26 case series, and one cohort study. Urinary samples from 533 patients were investigated. Fourteen studies reported the presence of COVID-19 in the urinary samples from 24 patients. The crude overall rate of COVID-19 detection in urinary samples was 4.5%. Considering case series and cohorts with a sample size of ≥ 9, the estimated viral shedding frequency was 1.18 % (CI 95%: 0.14 - 2.87) in the meta-analysis. Urinary viral load in most reports were lower than rectal or oropharyngeal samples. In adult patients, urinary shedding of COVID-19 was commonly detected in patients with moderate to severe disease (16 adult patients with moderate or severe disease versus two adult patients with mild disease). In children, urinary viral shedding of COVID-19 was reported in 4 children who all suffered from mild disease. Urinary viral shedding of COVID-19 was detected from day 1 to day 52 after disease onset. The pathogenicity of virus isolated from urine has been demonstrated in cell culture media in one study while another study failed to reveal replication of isolated viral RNA in cell cultures. Urinary symptoms were not attributed to urinary viral shedding., Conclusion: While COVID-19 is rarely detected in urine of infected individuals, infection transmission through urine still remains possible. In adult patients, infected urine is more likely in the presence of moderate or severe disease. Therefore, caution should be exerted when dealing with COVID-19 infected patients during medical interventions like endoscopy and urethral catheterization especially in symptomatic adult patients while in children caution should be exerted regardless of symptoms.

Objective: To evaluate the use of human amniotic membrane allograft to prevent urethrocutaneous fistula after tubularized incised plate repair for redo-hypospadias and anterior urethral defects., Methods: This pilot study included 28 patients (mean age 25.3 ± 11 years) with a history of previous failed hypospadia repair, who underwent tubularized incised plate urethroplasty in one session by the same surgical team from April 2016 to April 2019. After the reconstruction of a neourethra and proper hemostasis, a human amniotic membrane allograft - Grafting Scaffold - was used to cover the suture lines., Results: The mean follow-up time was 13.3 ± 4.5 months. Two urethrocutaneous fistulas occurred within the first 2 weeks after the surgery, one of which was caused by the infection of the surgical site. No penile torsion, urethral diverticula, meatal stenosis or glans dehiscence was reported., Conclusions: Amniotic membrane graft provides an applicable, low-cost, feasible, biodegradable and safe second cover in redo-hypospadias repairs by tubularized incised plate technique. Its use is technically easy; it has satisfactory cosmetic outcomes and might decrease urethrocutaneous fistula formation., (© 2020 The Japanese Urological Association.)

Purpose: Surgical repair of post-traumatic complex urethral stricture poses a major challenge to urologists. Here, we report six patients with irreparable urethral strictures who were successfully treated by using the appendix as conduit for urinary diversion., Materials and Methods: Six patients who had underwent urinary diversion using an appendix during 2015 to 2019 were included in our study. All patients had a history of one or more failed attempts of urethral reconstruction in the past. Mean follow-up for patients was 29 months. Continency was defined as being completely dry for at least 3 hours., Results: Mean age of patients was 40.1 years old (range: 20-70 years). Intermittent catheterization through the conduit was easily performed for every patient without any stomal stenosis. Mild stomal incontinence only occurred in one case which was resolved after a few months. All patients were continent during day and night., Conclusion: Based on the results of our study, Mitrofanoff's technique is a valuable procedure for managing patients with serious complicated urethral strictures who cannot be treated with common standard approaches.

Purpose: Prevention and treatment of urethroplastic postoperative pain is a major challenge in post-surgery care. gabapentin can treat postoperative pain by preventing excessive sensitivity to the central nervous system. we have tried to compare the effect of gabapentin with the placebo on reducing the pain associated with posterior urethroplasty in patients., Material and Method: This prospective, randomized, double-blind study was scheduled in Shohad e Tajrish hospital where a single dose of Gabapentin was compared with placebo given to patients preoperatively. In this study,100 patients with posterior urethral stricture were included for surgery with 50 patients in each arms .All patients underwent posterior urethroplasty. After surgery, the pain level is assessed and evaluated by the visual analog scale in two hours,four hours, six hours,eight hours, twelve hours, and 24 hours after the operation., Result: In this study, there was a significant difference in the pain level that was evaluated by the visual analog scale in two hours, four hours, six hours, eight hours, twelve hours, and 24 hours after the surgery (p.value <0.001). We also found a significant decrease in morphine consumption in the gabapentin group vs the placebo group. (p.value <0.001) The post-surgery assessments showed significant lower adverse effects such as vomiting, nausea, drowsiness, and pruritus in the gabapentin group vs. placebo group., Conclusion: The consequences of this study revealed that gabapentin effective in controlling posterior urethroplasty postoperative pain, consumption of opioid, nausea, vomiting, drowsiness, and pruritus compared with the placebo group.

Purpose: Autophagy plays a critical role in PCa development. DAXX has a potent pro-survival effect by enhancing cell growth in PCa via suppression of autophagy. Here, we depicted a network governed by DAXX and SPOP by which the autophagy pathway is suppressed through the ubiquitination and modulation of key cellular signaling pathways mediators including LAMP2 and RARRES1., Materials and Methods: Through network-based bioinformatics approaches, the expression levels of DAXX, RARRES1, LAMP2, and SPOP genes was assessed in 50 PCa tissues and 50 normal adjacent from the same sample as well as 50 benign prostatic hyperplasia (BPH) tissues by quantitative RT-PCR. The normal adjacent tissues were taken from regions more than 5mm away from the bulk of those tumor tissues with clearly distinct margins. RNA extraction, cDNA synthesis and Real-time Quantitative RT-PCR were done for assessment of gene expression. To evaluate the primary gene network centered on autophagy pathway, according to the Query-dependent weighting algorithm, these two networks were integrated with Cytoscape 3.4 software., Results: We found that in PCa tissues the DAXX expression level was significantly increased (P < 0.001) and the expressions of SPOP, RARRES1, and LAMP2 were significantly down-regulated, when compared to both control groups including normal adjacent and BPH tissues. Moreover, significant correlations were observed between expression levels of all four genes. Additionally, ROC curve analysis revealed that LAMP2 had the most sensitivity and specificity., Conclusion: These findings suggest that the contribution of SPOP, DAXX, RARRES1, and LAMP2 together could be a putative regulatory element acting as a prognostic signature and therapeutic target in PCa.

Purpose: The aim of the present study was translation, cross cultural adaptation and face validity evaluation of the Persian version of Patient-Reported Outcome Measure for Urethral Stricture Surgery (USS-PROM) Questionnaire., Materials and Methods: This study was assessed: translation, translation quality, reverse translation and comparison of the english version, Content validity, internal consistency and stability. Content validity presents by index of content validity (CVI) and the content validity ratio (CVR). Internal consistency reliability was tested by Cronbach's ?, and test-retest reliability was evaluated by Intraclass Correlation Coefficient (ICC) assessed by Guttman two way mixed absolute agreements., Result: Frothy males with history urethroplasty and mean age of 41.4±9.08 (range of 19 to 52) years old; enrolled.  In the case of mean scores of difficulty from the 16 translated items, 80% had easy translation. In terms of translation quality, 92% were the satisfactorily clear. In terms of similar concept, 92% were satisfactory. The overall quality of the translation was satisfactory at 88%. The translated questionnaire has a good internal consistency (Cronbach's alpha as 0.84). CVI and the CVR, test-retest ICC evaluation were appropriate/acceptable in all questions. The questionnaire ICC was .791(CI 95%, .678-.876). Two main different aspects of the questionnaire consisted of urinary symptoms (question 1-10) and Quality of life (question 11-15) Cronbach's alpha were .800 and .671 respectively., Conclusion: The Persian version of the questionnaire has acceptable cultural adaptation and face Validity. Further studies should be done using this translated tool to determine its applicability in the urethroplasty patients.

Introduction: Current methods for Urethral dilatation include filiforms and followers, metal sounds, balloon dilators, catheters of increasing size, introduction of a Council catheter over a guidewire, and coaxial dilators of increasing size. These methods however are effective but expensive and use of them is limited in many third world countries. In this retrospective study, we report the feasibility, complication and long-term follow-up of the newly Nelaton based urethral dilation method following by self calibration plan as a single referral center experience. Method: We reviewed the records of 333 men with urethral stricture longer than 1 cm over a 16-year period between March 2001 to December 2018. In this method the straight flexi-tip guide-wire is introduced through the urethra and advanced under cystoscopic vision. This wire then was used to guide the dilatation after withdrawal of the cystoscope. The tip of well-lubricated Nelaton urethral catheters incised and then advanced gently over the guide-wire serially from the smallest to the largest appropriate sizes. The patients were followed up regularly after the dilatation 1, 3, 6, 12 months and then annually postoperatively with taking history, PVR and uroflowmetry and all underwent retrograde urethrography at the 6 th and 12 th months of follow-up. Result: The mean age of patients was 39.19±16.9 years old (10 to 86 years). The mean period of the follow-up was 3.6±1.1 years (range, 3 to 4.3 years). Success rate after first attempted was 58.5% and after two attempted was 77.7% in two years follow up. After one year 51 (15.3%), two years 23 (6.9%) and after three years 11 (3.3%) cases required continued self dilatation once a month. Conclusion: Guide wire-assisted urethral dilatation is shown to be acceptable, cost-effective, simple, safe and feasible techniques for urethral dilation. Our technique may be the choice manner in selected patients with short memberanous urethral stricture, because of decrease the risk of incontinency., Competing Interests: None., (AJCEU Copyright © 2019.)

Introduction: Genital warts in young adults aged 18-28 years are very common. Several approaches are routinely used in the treatment of warts, viz., medical treatment (podophyllin and trichloroacetic acid), conventional surgery (excision or electrocautery), cryotherapy, and laser treatment. Because of high recurrence rates after treatment, complications and long duration of treatment, newer modalities have been developed. One of these newer methods is laser, which has been used in several urologic diseases. However, there are only a few studies about use of Holmium laser for treatment of genital warts. This retrospective study compared the success rate of Holmium laser with other available treatments for genital warts. Methods: Between October 2011 and May 2016, 142 patients with genital warts attended the urology clinics at Shohada-e-Tajrish hospital in Tehran, Iran. Out of these, a total of 101 patients were included in this study consisting of 42, 39, 11 and 9 patients treated with cryotherapy, laser, conventional surgery and podophyllin respectively. Results: The most successfully cleared lesions were seen in the holmium laser treatment group ( P =0.001). The lowest recurrence rate was observed in the holmium laser treatment group ( P =0.001). 17 patients had one of these following problems: dysuria, initial hematuria or a change in the force and caliber of their urinary stream that after physical examination showed them to have a meatal wart. These patients then underwent cystoscopy up to urinary sphincter. All of them in addition to the meatus wart had a penile shaft lesion(s). Thirteen patients had meatal lesions, 9 of whom received holmium laser therapy and 4 patients were treated with electrocautery. Based on routine follow up after treatment, none of the patients treated with holmium laser had urinary stricture, but one case treated with electrocautery returned with a penile urethral stricture. Conclusion: This study showed that treatment with Holmium laser has the highest clearance rate (92.2%) and lowest recurrence rate (14.3%) compared to other available treatments in this study. It may be concluded that holmium laser is a safe and effective treatment for genital warts with a low rate of recurrence.

Introduction: Urogenital system injuries (UGIs) are seen in 10% of adult cases with multiple trauma. Although UGIs are rarely life threatening, they can cause major long-term morbidities. This study aimed to evaluate the characteristics of traumatic UGIs in patients who were referred to emergency department following multiple traumas., Methods: This retrospective cross-sectional study was conducted on multiple trauma patients who were presented to emergency department during a 10-year period (2008-2017). All patients with kidney, ureter, bladder, urethra, or external genitalia injuries were studied. The patients' data were extracted from their clinical profiles., Results: Out of the 13598 admitted patients in our trauma center, UGIs were seen in 267 (1.9%) cases. The mean age of patients with UGIs was 27.3 ± 6.1 years (74.15% male). The highest incidence of UGI was seen in those aged between 21 and 30 years (39.7%) and motorcycle accidents (49%) was the most frequent cause of trauma. 221 patients had an unstable situation and were emergently transferred to operation room (13.57% with traumatic kidney injury). The most common injured sites of urogenital system were kidney with 155 (58%) cases, followed by external genitalia with 91 (34.1%) cases. 77.5% of cases were managed conservatively and the rest (22.5%) underwent surgical procedures., Conclusion: UGIs comprise a low percentage (2%) of traumatic injuries, which are mostly caused by blunt trauma due to road traffic accidents. Kidney is the most common injured organ and UGIs mostly happen in young ages., Competing Interests: The authors declare that there is no conflict of interest.

Introduction: The retrograde approach is a modification that makes the percutaneous cystolitholapaxy (PCCL) a more trendy method, especially in operating rooms with limited facilities. The transurethral approach for bladder calculi lithotripsy by a laser has become popular among urologists. In this study, we investigate the feasibility and safety of retrograde assisted access for PCCL in comparison with transurethral cystolithotripsy by the holmium-YAG laser (Ho: YAG). Methods: According to the type of intervention, the patients were stratified to two matched groups. In the retrograde-assisted percutaneous cystolitholapaxy (RPCCL) group, a Benique was conducted through the urethra into the bladder; palpating the suprapubic region, an about 1.5 cm incision was done over the tip, then an Amplatz sheath was placed over it, treading into the bladder; further cystolitholapaxy was done by a routine order. In transurethral Ho: YAG laser lithotripsy (TULL) via 200 µm fiber vaporize the stone. Results: A total of 124 male patients with the mean age of 50.33±9.64 years and the average stone burden of 3.35±1.07 cm were included in the study. The most common cause of vesical calculi was spinal cord injury. Statistically significant differences were found in terms of the mean operation time in favor of the RPCCL group (P≤0.05) and the mean hospital stay in favor of the TULL group (P≤0.05). The stone-free rate (SFR) was 100% in both methods after a onemonth follow-up. None of the interventions changed to open surgery. There were not any major complications in both methods. Conclusion: RPCCL is a safe and effective method in bladder stone treatment and is applicable in medical centres without Ho: YAG equipment., (Copyright © 2019 J Lasers Med Sci.)

Introduction: The management of Peyronie's disease (PD) has remained a therapeutic dilemma for physicians and there is no gold standard treatment. In this paper, we decided to investigate the beneficial effect of the intralesional administration of verapamil compared with the intralesional administration of verapamil plus a low-intensity laser (LIL). Methods: Research was activated from May 2016 to May 2018 and a total of 38 men aged 18 years and older completed the investigation. The subjects were randomly divided into 2 groups. Group 1 was composed of 22 patients that were treated only by verapamil (5 mg) plus a sham laser weekly for 6 weeks, and group 2 consisted of 22 patients that received a laser, using the BTL-6000 HIGH-INTENSITY LASER 12 W machine and the same protocol of intralesional verapamil injection. The visual analogue scale (VAS) was used to evaluate pain during an erection, penile ultrasonography was used to measure plaque size, the penile curvature angle degree was measured using the photographs taken during an erection, and the International Index of Erectile Function questionnaire was used to assess erectile function. The follow-up treatment lasted for nine months, with visits performed in the 3rd and 9th months. Results: All study parameters decreased significantly after treatment in both arms, but the reduction in pain and penile curvature improvements in combination therapy revealed more significant changes in 3 months (p = .035, p=.032). Nevertheless, these improvements were not seen in the follow-up session after 9 months. Conclusion: A laser appears to be safe treatment modality in carefully-selected patients with PD. It has moderate efficacy in the short term., (Copyright © 2019 J Lasers Med Sci.)

Purpose: There are some previous reports on the relationship between pathological grades and HPV detection. To determine the Human Papilloma Virus(HPV)  DNA in Tumor Tissue and Urine in Different Stage of Bladder Cancer conducted this study.Materials and Methods: Polymerase chain reaction (PCR) was used to detect general HPV and HPV16 and 18 subtypes in 110 bladder tumor tissue and urine specimens of patients with TCC of bladder between January 2014 to May 2016 that underwent transurethral resection of bladder tumor. Exclusion criteria were genital wart and cases with immunosupression., Results: Mean age of 110 patients was 61.6±10 years and fourteen (12.7%) of patients were female. PCR for general HPV primer in bladder tumor tissue was positive in 3 (9.4%), 22 (38.6%) and 15 (71.4%) of Ta, T1 and T2 bladder tumors, respectively (p<0.001). PCR for HPV16 in bladder tumor tissue was positive in 2(6.3%), 10 (17.5%) and 13 (61.9%) and PCR for HPV18 in bladder tumor tissue was positive in 1 (3.1%), 14 (24.6%) and 12 (57.1%) of Ta, T1 and T2 bladder tumors, respectively (p<0.001, p<0.001). Thirty seven (33.6%) of urine specimens were positive for general HPV using PCR and HPV16 and 18 subtypes were positive in 17 (15.5%) and 14 (12.7%) of urine specimens, respectively., Conclusion: HPV infection may be associated with higher stages and grades of bladder carcinomas. Urine sampling for HPV detection is is as reliable as tumor tissue sample which could be considered for prognostic and follow up implications.

Introduction: Transurethral lithotripsy (TUL) is an appropriate treatment for ureteral stones and is usually used for stones in the middle and lower part of the ureter. Different devices such as the Holmium laser, the stone basket, and the stone cone exist to prevent any fragments from retropulsion during TUL. The present study aims to compare the advantages and disadvantages of the Holmium laser, the stone basket, and the stone cone. Methods: A retrospective study was conducted from September 2016 to January 2018 comparing various TUL methods in 88 subjects with proximal ureteral calculi. The study participants were divided into 4 matched groups. The first one included 20 patients undergoing TUL with no device (group 1), the second group included 22 patients undergoing TUL while using the stone retrieval basket, the third group included 18 patients undergoing TUL while utilizing the stone cone and the fourth group included 28 patients undergoing TUL while using the Hol-YAG laser. Results: A residual stone ≥3 mm was recorded in 15.9% of the patients. The stone free rate was seen in 100%, 90.9, 83.3%, and 55% of the Holmium laser group, the retrieval basket group, the stone cone group and the no device group respectively ( P =0.001). The lowest rate of surgery complications including ureteral perforation, post-operative fever, and mucosal damage between the 4 groups ( P =0.003) and the highest time of surgery ( P =0.001) belonged to the laser group. If we want to ignore the laser group, the success rate for lithotripsy was better in both groups with a stone retrieval device compared to the no device group, but no advantage existed between the stone basket and the stone cone. Conclusion: We can safely conclude that lasers significantly help to prevent stone migration during TUL. If we want to ignore the laser group, the success rate for lithotripsy was significantly better in both groups with a stone retrieval device compared to the no device group, but no advantage existed between the stone basket and the stone cone., (Copyright © 2019 J Lasers Med Sci.)

Introduction: Many valid option modalities are available for the management of urethral stricture disease (USD), such as internal urethrotomy which has the success rates of 33%-60%. The aim of this study was to assess the outcome of holmium: YAG (Ho: YAG) laser urethrotomy (HLU). Methods: One hundred thirty-eight patients with urethral stricture with the mean age of 48±3.03 years old treated by HLU from March 2011 to August 2017. The main purpose of this investigation was to evaluate mean operation time, stricture recurrence rate and post-operation Qmax and complications of transurethral HLU. Results: The most common cause of USD was trauma in 82 (59.4%) patients. Mean laser operation time, mean hospital stay and mean postoperative duration of catheterization were 23.08 ± 9.1 minutes, 19.02 ± 10.7 hours and 10.3 ± 1.05 days respectively. The mean Qmax was 8.3 ± 2.07 mL/s before surgery and 16 ±3.1 mL/s afterward. At the end of 12 months follow-up, a total of 37 (26.8%) patients developed recurrence of the stricture. Patients with posterior, longer urethral strictures and previous history of interventions have more recurrence rate of the stricture. Conclusion: HLU is minimally invasive and seems to be an effective and safe management option for primary, short, urethral strictures. The hospital stay is remarkably short and complications are negligible.

The usage of laser in medicine is not recent, and its history in urology goes back to 40 years ago. For the last 2 decades, common uses of laser have been treatments of subjects with urolithiasis, bladder tumors, benign prostatic enlargement, lesions of the genitalia and urinary tract strictures. To evaluate laser application in urology in Iran, we reviewed all of the Iranian literature on the topic. This study was designed to retrieve all studies on laser application in urology in Iran, regardless of publication status or language, covering years 1990-2017. Twenty-six articles were identified: 12 about urolithiasis, 8 about benign prostatic hyperplasia (BPH), 2 case reports, 1 paper about prostate cancer, 1 on female urethral stricture, 1 review and 1 basic sciences study. We conclude that the use of this technology has not yet found its position in Iran, especially in the field of urology. The main causes for it are the difficult accessibility and disturb of laser devices and its accessories, as well as the lack of adequate knowledge of the medical community about this modality.

Introduction: Presently, different holmium: yttrium aluminum garnet (Ho:YAG) laser calibers are used for endoscopic stone treatment, which include 200, 365, 500 and 1000 Mm fibers. Currently, there are not enough studies to compare the performance of these fibers. In this retrospective investigation, we compared the outcome of 200, 365 and 500 Mm fibers of Ho:YAG laser in transurethral lithotripsy of ureteral stone. Methods: From January 2016 to June 2017, 74 subjects with mean age of 35.3 ± 5.6 were randomly allocated to 3 groups according to the caliber of laser, 200, 365 and 500 Mm for transurethral lithotripsy. The main purpose of this investigation was to evaluate mean operation time (MOT), stone free rate (SFR) and complications. Results: MOT and SFR were significantly different in 500 Mm laser caliber ( P =0.046, P =0.029, respectively). There was no remarkable difference between the 3 groups in this regard. Conclusion: Based upon our data, the clinical potency of the Ho: YAG laser was great in all 3 fiber calibers. The most important results of this comparison were the significantly higher SFR with increased laser caliber.

Introduction: Bladder stone is more common in developing countries and it is one of the rare diseases affecting children. In recent years, there is an increasing tendency in urologists to have minimal invasive approaches. The aim of this study was to compare the results of surgical bladder stone management in our single tertiary center. Methods: From 159 children younger than 18 years with vesical stones treated during January 2000 to January 2015 in Shohada-e-Tajrish hospital, Tehran, Iran, 146 subjects entered to the study. According to type of intervention, patients stratified to three groups. First group included 80 patients that open cystolithotomy (OCL) was done for them, second group was 39 patients who underwent percutaneous cystolithotomy (PCCL) and third group was 27 patients who treated by transurethral cystolithotripsy with holmium-YAG laser (TULL). Demographic data, hospital stay, operation time, and post operation complications were recorded and comparison were drawn between the three groups. Results: Mean age was 8.3±5.1 years (8.6±5.1, 6±4.2 years for boys and girls, respectively). Mean stone size (MSS) was 2.76±1.07 cm and no significant differences were found between the three groups but it was larger in OCL group. Mean operative time (MOT) was 29.15±7.12 minutes in separate; MOT in TULL was significantly higher than PCCL and OCL respectively (36.3±5.97, 30.54±5.27 and 26.06±6.32 minutes/ P =0.000). Mean hospital stay (MHS) in OCL group was 3.55±1 days that was higher than PCCL and TULL groups significantly ( P =0.000). Conclusion: Based on our study, holmium:YAG lithotripsy has a high success rate, and is a minimally invasive management, therefore it is a safe method for children bladder calculi treatment if proper equipment was available and done by expert hands.

Gossipyboma is a mass which is made around a cotton sponge or abdominal compress retained in a patient during surgery accidentally. Patients manifest with either acute or chronic symptoms due to complications. Here in wereported an 89-year-old man case of transvesical migration of gossipyboma who presented with gross hematuria with a history of transvesical prostatectomy 6 years ago. Patient underwent exploratory laparotomy with repairing of the bladder and peritoneum. He had no complications during surgery and was subsequently discharged.

Purpose: To compare monotherapy with tadalafil or tamsulosin and their combination therapy in men with benignprostatic hyperplasia and erectile dysfunction by comparing IPSS score, prostate volume and Qmax and someother outcomes., Materials and Methods: This randomized, single-blind, paralleled group clinical trial was done in 2013 on patientswho had referred to our hospital in Tehran. All patients with lower urinary tract symptoms, benign prostatichyperplasia and any grade of erectile dysfunction were recruited. They were randomly divided into three groups(61 participants in each group): Group A received 20 mg/daily tadalafil; Group B received 0.4 mg/daily tamsulosin;Group C receieved a combination of 0.4 mg/daily tamsulosin and 20 mg/daily tadalafil. Primary outcomeswere prostate volume, prostate specific antigen, post-void residual volume, IPSS score, LUTS severity, Qmax,IIEF and erectile dysfunction severity and secondary outcome was complications., Results: The mean ± SD of ultrasonographic prostate volume was 61.4 ± 15.1 mL and prostate specific antigenlevel was 2.4 ± 1.9 ng/dl. Post-void residual level was significantly different before and after the treatment, exceptfor group A. Also, this group had no meaningful difference compared to the other groups in this regard (P > 0.05).There were significant differences between pre- and post-treatment international prostate symptom scores in eachgroup (P < 0.05)., Conclusion: Combination of tamsulosin and tadalafil can improve international prostate symptom scores, internationalindex of erectile function questionnaire scores and Qmax in patients with lower urinary tract symptoms andbenign prostatic hyperplasia to more degrees than their separate use. This combination is recommended becauseof its synergistic effects, well toleration and safety.

Subcutaneous emphysema (SE) is a condition often causing minimal symptoms, but sometimes it can be severe and even life-threatening. This study is the first great survey about SE. The aim of this study is to classify and evaluate the etiology, signs, symptoms, and management of SE. This retrospective study was performed by reviewing patients who had been diagnosed as having SE in Rasht, between January 2001 and January 2011. We classified the severity of SE in five grades including the (1) base of the neck, (2) all of the neck area, (3) subpectoralis major area, (4) chest wall and all of the neck area, and (5) chest wall, neck, orbit, scalp, abdominal wall, upper limbs, and scrotum. We excluded all patients in grades 1 and 2, because the symptoms and signs were not significant. Statistical analysis was carried out with SPSS 18. We collected 35 cases of SE with the mean age of 53 ± 14.83 (71 % men). The most common cause of SE was pneumothorax with background of COPD and surgery in grade 5, trauma due to rib fracture in grade 4, and iatrogenicity in grade 3. We performed two bilateral 2-cm infraclavicular incisions. In our patients with infraclavicular incisions, expansion of the lung was better, and the patients' appearance improved. Infraclavicular incisions as a simple method for the management of SE can decrease the severity of SE with no cosmetic problem.
