On-demand use of fesoterodine: a new paradigm for extended release antimuscarinics.

INTRODUCTION AND HYPOTHESIS: We aimed to compare on-demand and continuous use of fesoterodine 4 mg concerning efficacy and adverse effects. METHODS: A total of 100 patients who were diagnosed with non-neurogenic overactive bladder (OAB) syndrome were included in the study. All patients were evaluated with MMSE, ICIQ-SF, SEAPI quality of health and OAB-V8 questionnaires, at the beginning, 1st month and 4th month. Fesoterodine 4 mg was started for treatment. At the end of the 1st month, patients who obtained benefit from the treatment were 1:1 randomized into two groups. In group 1, fesoterodine 4 mg was given 1 × 1 in a standard manner whereas in group 2 patients took the pills on demand. Both groups were evaluated for efficacy and adverse events at 4 months. RESULTS: Final analyses included 69 patients. At 4-month follow-up, OAB-V8 scores were significantly improved compared to 1 month in both groups. Again at h months, no difference was detected between the two groups for MMSE, ICIQ-SF and SEAPI scores. In continuous usage group, 4th month MMSE scores were significantly lower than 1st month scores. At 4 months, dry mouth and constipation were lower in the on-demand group compared to continuous usage group. CONCLUSIONS: Compared to standard continuous usage, on-demand usage of fesoterodine showed similar efficacy with fewer adverse events.

A novel nomogram and a simple scoring system for urinary leakage after percutaneous nephrolithotomy.

INTRODUCTION: The present study aimed to investigate the factors of prolonged urinary leakage (PUL) after percutaneous nephrolithotomy (PCNL) and develop a new and simple scoring system to predict it. PATIENTS AND METHODS: We retrospectively reviewed patients with renal stones who underwent PCNL at the University of Health Sciences Izmir Bozyaka Training and Research Hospital between April 2011 and January 2020. The patients were divided into two groups according to the presence of PUL, and their preoperative and perioperative data were compared. A multivariate regression analysis was applied to examine the relationship between perioperative descriptors and PUL, and a nomogram was developed using significant predictors. Then, the individual components of the nomogram were assigned points to form a scoring system. RESULTS: There were 92 and 840 patients in the groups with and without PUL, respectively. The results of the univariate logistic regression analysis showed that hydronephrosis grade, parenchymal thickness, duration of nephroscopy, and duration of nephrostomy catheter were significantly associated with PUL. Subsequently, a multivariate regression analysis was carried out with these four factors as possible independent risk factors of PUL after PCNL. Based on the results of this analysis, a nomogram prediction model was developed with an area under the curve value of 0.811, which was consequently used to develop a new simple score system consisting of three characteristics: parenchymal thickness (1-5 points), duration of nephroscopy (1-3 points), and hydronephrosis grade (1-3 points). CONCLUSION: A novel scoring system is a useful tool for predicting PUL in patients who have undergone percutaneous nephrolithotomy.

External validation and comparison of current scoring systems in retrograde intrarenal surgery: Multi-institutional study with 949 patients.

OBJECTIVES: To externally validate and compare Resorlu-Unsal stone score (RUSS), modified Seoul National University Renal Stone Complexity Score(S-ReSC), Ito's nomogram, and Retrograde Intra-Renal Surgery (R.I.R.S.) scoring systems for predicting capabilities of both the stone-free status and complications in a multi-institutional study. MATERIALS AND METHODS: We performed a retrospective analysis of 949 patients who underwent flexible ureterorenoscopy (f-URS) and laser lithotripsy for renal stones in two institutions between March-2015 and June-2020. The RUSS, modified S-ReSC, Ito's nomogram, and R.I.R.S. scores were calculated for each patient by the same surgeon on imaging methods. Results were compared for their predictive capability of stone-free status and complications. RESULTS: Of 949 patients 603 were male and 346 were female with a mean age of 47.2 ± 14.3 (range 2-84 years). Mean stone burden was 102.6 ± 42.2 (48-270 mm2 ). All nomograms predicted stone-free status (Area Under Curve (AUC) were 0.689, 0.657, 0.303, and 0.690, respectively). All four scoring systems predicted complications with AUC values of 0.689, 0.646, 0.286, and 0.664 for RUSS, modified S-ReSC, Ito's nomogram, and R.I.R.S., respectively. Although all scoring systems were able to predict complications only Ito's nomogram was able to predict Clavien ≥2 complications. CONCLUSION: All four scoring systems (RUSS, modified S-ReSC, Ito's nomogram, and R.I.R.S.) could predict stone-free status after f-URS, however, the AUC values are not satisfactory in our large patient cohort. Although these scoring systems were not developed for predicting post-operative complications, they were associated with complications in our study. However, these four scoring systems have some significant limitations. The ideal scoring system is yet to be developed.

Predictive Value of Additional Clinical and Radiological Parameters for Discrimination of Malignancy in Bosniak 3 Cysts.

INTRODUCTION: Almost half of the cystic renal lesions are still overdiagnosed and overtreated. New clinical and radiological parameters are needed to distinguish the malignant Bosniak 3 lesions from the benign ones. We aimed to evaluate the clinical and radiological parameters that may be related to malignancy risk for Bosniak category 3 renal cysts. MATERIALS AND METHODS: Patients who underwent surgical resection of a histopathologically confirmed Bosniak 3 renal cyst between March 2007 and September 2019 were evaluated. Two experienced uro-radiologists have reevaluated the last preoperative computed tomography and/or MRI images of the patients and reclassified the lesions according to the Bosniak classification. They also reported cystic features such as nodularity, septation, focal thickening, enhancement, and calcification. Clinical, pathological, and oncological outcomes were recorded. Then patients were divided into 2 groups as Group 1 (benign pathology) and Group 2 (malignant pathology) according to final histopathological report. RESULTS: A total of 79 patients were included in this study. Mean follow-up time was 47 ± 34 months. There were 30 patients in Group 1 and 49 patients in Group 2. Hypertension (p = 0.001) and smoking history (p = 0.008) were more common in malignant group. Among the radiological findings, lower tumor diameter (p = 0.024), presence of cyst wall enhancement (p = 0.025), presence of nodularity (p = 0.002), and presence of focal thickening (p = 0.031) were found to be statistically significant for malignancy. Most of the tumors were at pathological T1 stage and Fuhrmann Grade 1-2. Only nodularity was found to be independent predictive factor for malignancy in multivariate analysis. CONCLUSION: Clinical factors including hypertension and smoking, radiological factors including lower lesion size, cyst wall enhancement, nodularity, and focal thickening were predictors for malignancy of Bosniak 3 cysts.

Effects of the transobturator tape procedure on overactive bladder symptoms and quality of life: a prospective study.

INTRODUCTION: This study aimed to evaluate the effects of transobturator tape (TOT) on overactive bladder (OAB) symptoms and quality of life. MATERIALS AND METHODS: Patients with stress-predominant mixed urinary incontinence (MUI) who had undergone TOT procedures were considered candidates for this research. Preoperative assessment included anamnesis, pelvic examination, cough stress test (CST), and validated symptom severity and quality of life (QoL) questionnaires. The primary outcome, improvement and cure rates of OAB symptoms were determined based on the patient's baseline scores in symptom-related questions in OAB-V8. Secondary outcomes included the success rates of SUI, changes in the QoL score and patient satisfaction rates. RESULTS: A total of 104 patients were included in the study. Sixty-two patients underwent TOT placement alone, and 42 patients underwent TOT placement along with prolapse surgery. The mean follow-up period of the patients was 30.47 months range: 13-52 months. At the fi rst-year follow-up, 52 patients (50.0%) and 59 patients (56.7%) reported cure in preoperative urgency and urgency incontinence, respectively. The objective and subjective cure rates were 96.2% and 56.7%, respectively. A total of 80.7% of the cases had a 15-point improvement in QoL scores. CONCLUSIONS: MUS is not only a gold standard treatment in SUI but also presents as a promising treatment modality in stress-dominant MUI. Although the improvement rates of OAB symptoms signifi cantly decrease over time, QoL and patient satisfaction rates remain higher than any other treatment in this patient group at the third-year follow-up.

Effect of variant histology presence and squamous differentiation on oncological results and patient's survival after radical cystectomy.

OBJECTIVE: To evaluate the effect of variant histology on pathological and survival findings in patients undergoing radical cystectomy due to muscle invasive bladder cancer. MATERIALS AND METHODS: Data from 146 patients with radical cystectomy performed due to muscle-invasive urothelial carcinoma between January 2006 to November 2016 at our clinic were investigated. The preoperative and postoperative data of patients with variant histology were compared with nonvariant urothelial carcinoma patients. Then of patients with variant histology only those with squamous differentiation (SqD) were compared with nonvariant urothelial carcinoma patients in terms of preoperative, postoperative and survival data. RESULTS: Of the 146 patients, 23 had carcinoma with variant histology. Of these, 17 had SqD, 4 had glandular differentiation, 1 patient had plasmocytoid variant and 1 patient had sarcomatoid variant. In patients with variant histology, postoperative T stage and upstaging was higher, with no difference observed in terms of overall and cancer-specific survival compared with nonvariant urothelial cancer patients. SqD patients were observed to have higher postoperative T stage compared to nonvariant urothelial cancer patients, with no significant difference observed in terms of survival. CONCLUSIONS: In cystectomy pathologies, patients with variant histology (especially SqD patients) were observed to have proportionally higher T stage compared to nonvariant urothelial carcinoma; however there were no significant differences for overall survival and cancer-specific survival.

Surgical management of female paraurethral cyst with concomitant stress urinary incontinence.

Paraurethral cysts are usually asymptomatic and frequently detected incidentally during routine pelvic examination however, patients can present with complaints of a palpable cyst or with lower urinary tract symptoms (LUTS) and also dyspareunia. In most cases, diagnosis can be made on physical examination but for more detailed evaluation and to differentiate from malign lesions ultrasonography (US), voiding cystourethrogram (VCUG), computerized tomography (CT), or magnetic resonance imaging (MRI) can also be used. Management of symptomatic paraurethral cyst is surgical excision. In this video our objective is to show the surgical management of female paraurethral cyst with concomitant stress urinary incontinence (SUI). A 37 year-old woman presented with an 8-year history of progressive urinary symptoms, consisting of dysuria, urinary frequency, urgency urinary incontinence, SUI and dyspareunia. Physical examination in the lithotomy position revealed a cystic lesion located in the left anterolateral vaginal wall. Also cough stress test for SUI was positive. Her preoperative ICI-Q, UDI-6, IIQ-7 and SEAPI scores were 16, 8, 9 and 18 respectively. Vaginal US revealed a solitary 2 cm paraurethral cyst, localized in the distal urethra. Pelvic MRI also revealed a benign cystic lesion in the distal urethra. The patient underwent surgical excision of the cyst and anterior colporrhaphy for SUI. At third month visit the patient was very satisfied. The ICI-Q, UDI-6, IIQ-7 and SEAPI scores were 0. Sometimes the LUTS concurring with the parauretral cyst can be dominant. Herein we want to show that extra surgical procedures can be necessary with paraurethral cyst excision for full patient satisfaction.

Telerounding & telementoring for urological procedures.

Telemedicine is the use of medical information exchanged from one site to another via electronic communications to improve a patient's clinical health status. Telemedicine includes a growing variety of applications and services using two-way video, email, smart phones, wireless tools and other forms of telecommunications technology. Starting out over forty years ago with demonstrations of hospitals extending care to patients in remote areas, the use of telemedicine has spread rapidly and is now becoming integrated into the ongoing operations of hospitals, specialty departments, home health agencies, private physician offices as well as consumer's homes and workplaces. There's also a current trend in the use of telemedicine in urology. In the present paper we aimed to review the recent literature about telemedicine and the use of telerounding and telementoring in urological procedures.

Outcomes of two different incision techniques for surgical treatment of stress urinary incontinence with concomitant anterior vaginal wall prolapse.

PURPOSE: To assess the outcomes of two different incision techniques used in the surgical treatment of stress urinary incontinence (SUI) with concomitant anterior vaginal wall prolapse and to identify possible associated risk factors with a medium-term follow-up in patients who underwent TOT procedure. METHODS: We conducted a retrospective cohort study of 233 women who underwent transobturator tape procedure with cystocele repair. The women were divided into two groups according to two different incision techniques. The outcomes were analyzed considering five postoperative parameters: objective cure, subjective cure, patient satisfaction, resolution of urgency urinary incontinence and complications. The mean follow-up period was 43.6 months (range 12-85). RESULTS: A total of 226 women were documented in this study: 79 women in single-incision technique (group 1) and 147 women in double-incision technique (group 2). The objective and subjective cure and patient satisfaction (visual analog scale score ≥80) rates were 89.8, 73.4, 84.8 % and 90.4, 74.1, 86.4 % in group 1 and group 2, respectively. Complications reported according to the Clavien-Dindo classification were grade I 5.2 %, grade II 42.1 %, grade IIIa 47.3 %, and grade IIIb 5.2 %, and grade I 22.2 %, grade II 77.7 %, grade IIIa 0 % and grade IIIb 0 % in group 1 and group 2, respectively. The mean operative time was significantly shorter in group 1 compared to group 2 (p = 0.001). CONCLUSIONS: Both incision techniques have satisfactory outcomes in the surgical treatment of SUI with cystocele; nevertheless, the postoperative complications favor the double-incision technique.

Patient and partner outcome of inflatable and semi-rigid penile prosthesis in a single institution.

INTRODUCTION: Penile prostheses are subject to a continuous development and have gained better mechanical reliability and safety during the last decades. In this study, we aimed to investigate the outcomes and satisfaction rates of inflatable penile prosthesis (IPP) and semirigid penile prosthesis (SPP) implantation. MATERIALS AND METHODS: From August 2001 to June 2012, 257 men with erectile dysfunction (ED) underwent penile prosthesis implantation (PPI) at our institution. Of the 257 patients, 118 underwent implantation of IPP and 139 underwent SPP implantation. The pre-operative and post-operative erectile status of the patients were assessed by international index of erectile function (IIEF) questionnaire. The satisfaction of patients and partners were evaluated by a telephone interview using the erectile dysfunction inventory of treatment satisfaction (EDITS) questionnaire and EDITS partner survey. RESULTS: The overall major complication rate was higher in IPP group. PPI led to a significant improvement in IIEF scores in both groups. For IPP and SPP groups the average EDITS scores were 78±11and 57±8, respectively, and that for the partners were 72±10 and 49±7, respectively (p<0.05). CONCLUSION: Although the IPP implantation have better satisfaction rates, the SPP implantation is still a viable treatment option in the surgical treatment of ED because of low cost and high durability with acceptable satisfaction rates.

Does concomitant vaginal prolapse repair affect the outcomes of the transobturator tape procedure in the long term?

INTRODUCTION AND HYPOTHESIS: Little information is available on the effects of concomitant vaginal prolapse repair on the outcomes of the transobturator tape (TOT) procedure. The purpose of this study is to assess the results and complications of TOT when combined with vaginal prolapse repair with a long-term follow-up. METHODS: We conducted a retrospective cohort study of 232 female patients who underwent the TOT procedure at two institutions. There were two groups: group 1 consisted of patients who had undergone TOT alone and group 2 consisted of patients who had undergone concomitant vaginal prolapse repair. The outcomes were analyzed considering four postoperative parameters: objective cure, subjective cure, resolution of urgency urinary incontinence (UUI), and patient satisfaction. The mean follow-up was 66.3 months (range 60-85). RESULTS: A total of 117 patients in group 1 and 104 patients in group 2 were documented in this study. The subjective and objective cure rates were 87.17%, 64.95% in group 1 and 89.42%, 68.26% in group 2. Patient satisfaction rates (visual analog scale [VAS] score ≥80) were 71.79 and 83.65% in groups 1 and 2 respectively (p = 0.035). Complications were reported according to the Clavien-Dindo classification with grade I 7.7%, grade II 69.2%, grade IIIa 7.7%, and grade IIIb 15.4%, and grade I 9.5%, grade II 47.6%, grade IIIa 42.8%, and grade IIIb 0% in groups 1 and 2 respectively. CONCLUSIONS: Concomitant vaginal prolapse repair with TOT does not have any negative effects on continence outcomes; on the contrary, it increases patient satisfaction.

Comparison of the effect of hyperbaric oxygen therapy and tadalafil daily use on erectile function: a prospective, double controlled study.

PURPOSE: Erectile dysfunction (ED) is a worldwide health problem. Oral phosphodiesterase type 5 inhibitors (PDE5I) are used in its first-line treatment. This study aimed to compare the effects of hyperbaric oxygen (HBO) treatment with PDE5I treatment and determine the patient-dependent factors affecting the efficacy of the HBO treatment and duration of action of HBO treatment. METHODS: Adult male patients who presented to the HBO unit for HBO treatment with non-urological indications and had ED based on the International Index for Erectile Function (IIEF-5) constituted the target population of this study. Participants were given HBO treatment (Group 1), no treatment (Group 2), or daily oral tadalafil 5 mg treatment (Group 3). The treatment duration was 1 month. Patients were assessed by IIEF-5 both initially and after the completion of 1 month. RESULTS: There were significant increases in the mean IIEF-5 scores of the patients in Group 1 and Group 3 (p < 0.001, p < 0.001). However, there was no significant improvement in Group 2 (p = 0.496). Also, the post-treatment IIEF-5 scores of Group 1 and Group 3 were significantly higher than Group 2 (p < 0.001). There was no significant difference between the IIEF-5 scores and ∆IIEF-5 values of Group 1 and Group 3 (p = 0.166, p = 0.093). Evaluation regarding comorbidities revealed that patients with the peripheral vascular disease did not improve with HBO treatment (p = 0.285). CONCLUSION: HBO can improve erectile functions, and it can be a reasonable alternative for patients who cannot use PDE5Is due to comorbidities or treatment side effects.

Management of Priapism: Results of a Nationwide Survey and Comparison with International Guidelines.

OBJECTIVE: The aim of this study is to evaluate current urologic practice regarding the management of priapism in Turkey and compare with international guidelines. METHODS: Urologists and urology residents were invited to an online survey consisting of 30 multiple-choice questions on priapism-related clinical practices that were consid- ered most important and relevant to practices by using Google Forms. RESULTS: Total number of responses was 340. Respondents reported that they recorded a detailed patient's medical history and physical examination findings (n = 340, 100%) and laboratory testing, which includes corporal blood gas analysis (n=323, 95%). Participants announced that they performed Doppler ultrasound for 1/4 cases (n = 106, 31%), but 22% of the participants (n=75) replied that they performed in >75% of cases. Participants (n=311, 91%) responded that the first-line treatment of ischemic priapism is decompression of the corpus cavernosum. Moreover, most respondents (n = 320, 94%) stated that sympathomimetic injection drugs should be applied as the second step. About three-quarters of respondents (n = 247, 73%) indicated adrenaline as their drug of choice. Phosphodiesterase type 5 inhibitors seems to be the most pre- ferred drug for stuttering priapism (n=141, 41%). Participants (n=284, 84%) replied that corpora-glanular shunts should be preferred as the first. A large number of par- ticipants (n = 239, 70%) declared that magnetic resonance imaging can be performed in cases with delayed (>24 hours) priapism to diagnose corporal necrosis. Most of the participants (84%) responded that penile prosthesis should be preferred to shunts in cases with delayed (>48 hours) priapism. CONCLUSION: It would be appropriate to improve the training offered by professional associations and to give more training time to the management of priapism during residency.

Retroperitoneal laparoscopic pyelolithotomy in an ectopic pelvic kidney.

BACKGROUND AND OBJECTIVES: Retroperitoneal laparoscopic pyelolithotomy was performed in an ectopic pelvic kidney with renal pelvis calculi. METHODS AND RESULTS: Laparoscopic pyelolithotomy was successfully performed in an ectopic pelvic kidney by using the retroperitoneal route. The total operation time was 130 minutes, and the estimated blood loss was < 50 mL. The patient was discharged on the second postoperative day without any complications. CONCLUSION: Laparoscopic pyelolithotomy is an effective treatment option for management of stones in the pelvis of an ectopic pelvic kidney. The retroperitoneal route may help to avoid intraoperative and postoperative complications.
