Randomized, controlled trial of fesoterodine fumarate for overactive bladder in Parkinson's disease.

AIMS: To evaluate short-term efficacy and safety of fesoterodine fumarate in Parkinson's disease (PD) patients with overactive bladder (OAB) symptoms. METHODS: This is a randomized, double-blind, placebo-controlled study. It also has an open-label extension phase. From May 2016 to May 2018, 63 patients were randomized to receive fesoterodine 4 mg or placebo for 4 weeks. At the end of 4 weeks of randomization phase, patients were received fesoterodine fumarate 4 mg daily for another 4 weeks at the open-label extension phase. The change in the mean number of micturition episodes per 24 h period was the primary outcome measure of the study. RESULTS: The number of micturition episodes per 24 h period significantly improved with the use of fesoterodine fumarate in the double-blind phase (p < 0.001). Also the mean number of nocturia and urgency episodes decreased in the fesoterodine group. In the open-label phase, the mean number of micturition, urgency and urgency urinary incontinence episodes were improved significantly. The number of nocturia episodes did not change in the open-label phase. Cognitive functions were stable after 4 weeks of fesoterodine 4 mg treatment. CONCLUSIONS: OAB symptoms were significantly improved in older adults with PD under fesoterodine fumarate treatment, and this advantage continued in the open-label portion in the short term. In this randomized controlled study, the cognitive functions of the participants were not affected by fesoterodine 4 mg treatment compared with placebo.

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.

The effect of additional telerounding on postoperative outcomes, patient and surgeon satisfaction rates in the patients who underwent percutaneous nephrolithotomy. / El efecto de televisitas adicionales sobre los resultados postoperatorios y la satisfacción de pacientes y cirujanos tras Nefrolitotomía percutánea.

INTRODUCTION: We wanted to investigate the potential effect of additional telerounding system on postoperative outcomes, patient and surgeon satisfaction rates in the patients who underwent percutaneous nephrolithotomy (PNL). METHODS: Eighty patients who underwent PNL were included in the study. The patients were randomly divided to two groups. Group 1 included 40 patients who were followed-up with standard rounds and group 2 included 40 patients who were followed-up with telerounding in addition to standard rounds. Patient and surgeon satisfaction rates were assessed with a visual analog scale (VAS) where 0 point represents very dissatisfied and 100 points very satisfied. RESULTS: Mean time of preoperative telerounding visit was 3.65±0.59 (2-4) minutes. Mean time of telerounding visits on the postoperative 1st and 2nd days was 3.80±0.62 and 2.9±0.91 minutes respectively. The VAS score evaluating the surgeon's satisfaction rate for telerounding was 91±11.2 and patients expressed a high level of satisfaction with 72.5%. CONCLUSION: The use of additional telerounding in urological patient care provides high satisfaction rates for both the patients and the surgeon. However the findings of the present study don't underestimate the importance of personal surgeon-patient interaction.

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.

Hydronephrosis due to a Migrated Intrauterine Device into the Ureter: A Very Rare Case.

Intrauterine device (IUD) insertion is a long-acting and one of the most effective modes of reversible contraception. Complications that most commonly arise following IUD insertion are failed insertion, pain, vasovagal reactions, infection, menstrual abnormalities, and expulsion. In this paper, we present the case of a woman who experienced hydronephrosis due to the migration of IUD into the ureter after 30 years of insertion. To the best of our knowledge, this is the third such case reported in the literature.

A novel method for prediction of stone composition: the average and difference of Hounsfield units and their cut-off values.

PURPOSE: The purpose of the study was to investigate the predictive value of stone measurements by including a novel method on non-contrast computed tomography (NCCT) images for stone composition. METHODS: We retrospectively evaluated patients who had stone analysis, NCCT images, and underwent percutaneous nephrolithotomy between 2013 and 2016. Patient characteristics, stone measurements on NCCT images, and stone analysis results were evaluated. Hounsfield unit (HU) values (maximum (HUmax), minimum (HUmin), and average (HUave) of HU values) were investigated on NCCT images. HUdiff was calculated as the difference between the HUmax and the HUmin values. Patients were divided into seven stone groups and data were compared. Then patients were separately divided into two groups according to mineral complexity (mono-mineral and multi-mineral groups) and calcium-based (calcium and other stone groups) evaluation. RESULTS: In the study, 115 patients were evaluated. Age, gender, HUmin, HUmax, and HUave were significantly different between the stone groups. HUdiff and HUave were found to be 341.5 HU (AUC = 0.719, p = 0.017) and 1051.5 HU (AUC = 0.701, p = 0.029) as cut-off, respectively. Seventy of 72 > 341.5 HUdiff patients and 64 of 67 > 1051.5 HUave patients had multi-mineral stones (p = 0.001, OR 9.26, and p = 0.028, OR 4.27), respectively. In multivariate analysis, > 341.5 HUdiff rate was significantly higher in multi-mineral and calcium stone groups; HUave was also significantly higher in the calcium stone group. CONCLUSIONS: HUdiff and HUave were significant predictors of mineral complexity. HUdiff of < 341.5 HU showed 81.8% sensitivity and 67.2% specificity for identification of mono-mineral stones.

External validation and comparison of the scoring systems (S.T.O.N.E, GUY, CROES, S-ReSC) for predicting percutaneous nephrolithotomy outcomes for staghorn stones: A single center experience with 160 cases.

The aim of this study was validation and comparison of stone scoring systems (S.T.O.N.E, GUY, CROES, S-ReSC) used to predict postoperative stone-free status and complications after percutaneous nephrolithotomy (PCNL) for staghorn stones. A total of 160 patients who had staghorn renal stones and underwent PCNL between January 2012 and August 2015 were included in the current retrospective study. Guy, S.T.O.N.E., S-ReSC (Seoul National University Renal Stone Complexity) and CROES (Clinical Research Office of the Endourological Society) nephrolithometry scores were calculated for each patient, and their potential association with stone-free status, operative and fluoroscopy time, and length of hospital stay (LOS) were evaluated. Postoperative complications were graded according to the modified Clavien classification, and the correlation of scoring systems with postoperative complications was also investigated. The mean CROES, S.T.O.N.E, Guy and S-ReSC scores were 143.5 ± 33.6, 9.7 ± 1.6, 3.5 ± 0.5 and 6.2 ± 2.0 respectively. The overall stone-free rate was 59%. All scoring systems were significantly correlated with stone-free status in univariate analysis. However, Guy and S-ReSC scores were the only significant independent predictor in multivariate analysis. And all four nomograms failed to predict complication rates. Current study demonstrated that Guy and S-ReSC scoring systems could effectively predict postoperative stone-free status for staghorn stones. However all four scoring systems failed to predict complication rates.

External Validation and Comparisons of the Scoring Systems for Predicting Percutaneous Nephrolithotomy Outcomes: A Single Center Experience with 506 Cases.

BACKGROUND: To validate and compare the stone scoring systems (stone size [S], tract length [T], obstruction [O], number of involved calices [N], and essence or stone density [E] [S.T.O.N.E.], Guy's Stone Score [GSS], Clinical Research Office of the Endourological Society [CROES], and Seoul National University Renal Stone Complexity [S-ReSC]) used to predict postoperative stone-free status and complications after percutaneous nephrolithotomy (PCNL). METHODS: A total of 567 patients who underwent PCNL for renal stones between January 2012 and August 2015 were included in the recent retrospective study. Sixty-one patients who had not done preoperative CT were excluded from the study. GSS, S.T.O.N.E., S-ReSC, and CROES nephrolithometry scores were calculated for each patient, and their potential association with stone-free status, operative and fluoroscopy time, and length of stay (LOS) was evaluated. Postoperative complications were graded according to the modified Clavien classification, and the correlation of scoring systems with postoperative complications was also investigated. RESULTS: The mean CROES, S.T.O.N.E., GSS, and S-ReSC scores were 203.7 ± 59.8, 7.52 ± 1.8, 2.08 ± 0.9, and 3.35 ± 2.2, respectively. The overall stone-free rate was 77.9%. All scoring systems were significantly correlated with stone-free status and operation time. While GSS, S.T.O.N.E., and CROES systems were significantly correlated with complication rates (CR), S-ReSC score failed to predict CR. All scoring systems except S.T.O.N.E. were significantly correlated with LOS. CROES and S-ReSC scores were predictive of estimated blood loss (EBL), while GSS and S.T.O.N.E. failed to predict EBL. CONCLUSIONS: Recent study demonstrated that S.T.O.N.E., GSS, CROES, and S-ReSC scoring systems could effectively predict postoperative stone-free status. Although S-ReSC scoring system failed to predict CR, the rest three scoring systems were significantly correlated with postoperative CR.

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.

Predictive value of preoperative neutrophil-to-lymphocyte ratio on the prognosis of germ cell testicular tumors.

OBJECTIVE: We investigated the prognostic value of preoperative neutrophil-to-lymphocyte ratio (NLR) on germ cell testicular tumors (GCT). MATERIAL AND METHODS: The data of 53 patients who underwent inguinal orchiectomy were analyzed retrospectively. NLR was calculated from the preoperative complete blood cell counts. Receiver operating characteristic (ROC) analysis was performed to find the threshold values for NLR. Correlations between cancer-specific survival (CSS) and progression-free survival (PFS) and NLR were evaluated. RESULTS: The mean follow-up time was 23.55±18.06 months. The mean level of NLR was 3.08±1.81. Optimal threshold values of NLR was calculated as 3.55 for PFS (area under curve, AUC: 0.55) and 3.0 for CSS (AUC: 0.66). For patients with a NLR of <3.55 and NLR of ≥3.55, mean times-to-progression were 55.71 months (95% CI, 51.27-60.14) and 51.95 months (95% CI, 38.02-65.87, p=0.152), respectively. As well as, for patients with a NLR of <3.0 and NLR of ≥3.0, mean times-to-cancer specific death were 54.72 months (95% CI, 49.05-60.38) and 49.43 months (95% CI, 37.64-61.22, p=0.119), respectively. CONCLUSION: Preoperative NLR is not a useful tool to predict the prognosis of patients with GCT.

Simple renal cysts in the solitary kidney: Are they innocent in adult patients?

In patients with a solitary kidney; residual renal volume is an important prognostic factor for kidney survival. At present, the impact of renal cysts on solitary kidney survival is not clear. The aim of this study is to examine the association of cysts on progression of renal failure in patients with a solitary kidney. METHODS: This study included sixtyfive solitary kidney patients. The remaining kidneys after indication nephrectomy (IN) were evaluated with urinary system ultrasound. The primary outcome of the study is the progression of kidney failure during follow-up which was defined as: 25% decrease in glomerular filtration rate (GFR) and / or the need for renal replacement therapy (RRT). RESULTS: The mean age of the patients was 55 ± 14 years and mean follow-up was 53 ± 27 months. Renal cysts were present in 30.7% of patients. 33.8 percent of patients had kidney disease progression and 10.7 % required RRT. Those with progressive disease were older (61 ± 13, 52 ± 14; P = 0.011), had lower baseline GFR (30 ± 11, 39 ± 18; P = 0.035), higher proteiuria (2.84 ± 0.58, 2.47 ± 0.57; P = 0.031) and frequently harboring cysts in the solitary kidney (52.3%, 20.4%; P = 0.006). Progression to kidney failure and RRT requirement in cases with or without renal cysts was (60% vs. 22%; P = 0.004) and (20% vs. 6.6%; P = 0.123), respectively. Acquired cysts in solitary kidney was independently associated with progression to kidney failure and RRT respectively (Exp(B) 3.173; P = 0.01 and Exp(B) 12.35; P = 0.04). CONCLUSION: Simple renal cysts in solitary kidney patients with impaired renal function is associated with poor renal outcome. Large-scale studies are needed to clarify this issue.

Comparison of S.T.O.N.E and CROES nephrolithometry scoring systems for predicting stone-free status and complication rates after percutaneous nephrolithotomy: a single center study with 262 cases.

The aim of this study was to compare the accuracy of the CROES nephrolithometric nomogram and S.T.O.N.E. scoring system in predicting PCNL outcomes in terms of stone-free rate, estimated blood loss (EBL), operative time (OR), length of hospital stay (LOS), and complications. Patients who underwent PCNL for renal stones between May 2012 and January 2015 were analyzed retrospectively. The patients' demographic characteristics and operational features were recorded prospectively in all patients postoperatively. S.T.O.N.E. and CROES nephrolithometry scores' correlation with stone-free status, operation and fluoroscopy time, length of hospital stay (LOS) and blood loss (BL) was evaluated. Patients were categorized according to S.T.O.N.E. nephrolithometry and CROES nephrolithometry scores. Postoperative complications were graded according to modified Clavien classification (Dindo et al. in Ann Surg 240:205-213, 2004) and the correlation of both scoring systems with postoperative complications was also evaluated. We identified 437 patients who underwent PCNL between May 2012 and January 2015. A total of 262 patients who are available data for the CROES and S.T.O.N.E. scoring systems were included in the recent study. The mean S.T.O.N.E score was 7.65 ± 1.56 and the mean CROES score was 191.13 ± 64.39. The overall stone-free rate was 71.4%. Of the 262 patients, 89 experienced postoperative complications. Stone-free patients had significantly lower BMI (<0.001) and stone burden (p < 0.001). Regression analysis showed that both scoring systems were significantly associated with stone-free rates and operation time. We demonstrated that S.T.O.N.E. and CROES scoring systems were useful for predicting post-PCNL stone-free status. But both scoring systems were not useful for predicting post-PCNL complications.

Can Doppler ultrasonography twinkling artifact be used as an alternative imaging modality to non-contrast-enhanced computed tomography in patients with ureteral stones? A prospective clinical study.

We aimed to evaluate the use of twinkling artifact (TA) on color Doppler ultrasonography (USG) as an alternative imaging modality to non-contrast-enhanced computed tomography (CT) in patients with ureteral stones in this prospective study. Totally, 106 consecutive patients who had been diagnosed with ureterolithiasis by CT were enrolled in this prospective study. A urinary system color Doppler ultrasonography was performed on the same day with CT by an experienced radiologist who was blinded to the CT scan. TA was graded as 0, 1 and 2. The overall specificity of TA was calculated according to the NCCT as a gold standard method. The size, side and localization of stone and the demographic characteristics of patients were compared with twinkling positivity. TA on color Doppler USG was detected in 92 (86.8 %) patients. Statistically significant difference was found between the TA and localization of ureteral stones (p = 0.044). When we sub-grouped the patients according to the TA grades as 0, 1 and 2, 14 patients were with TA grade 0, 55 with TA grade 1 and 37 with TA grade 2. The mean stone size of groups was significantly different (p = 0.012). Bigger and proximal ureteral stones tended to have more TA on color Doppler USG. TA on color Doppler USG could be a good and safe alternative imaging modality with comparable results between NCCT. It could be useful for the diagnosis and follow-up of patients with ureterolithiasis.
