Abstract Introduction: While percutaneous nephrolithotomy (PCNL) is often the procedure of choice for renal and ureteral calculi in transplant kidneys, retrograde ureteroscopy (URS) is a less frequently applied but excellent option if stone burden is small. We retrospectively examined nine surgical cases performed in seven patients in what appears to be the largest single institutional series reported to date.
Materials and methods: Seven patients underwent nine retrograde URS between June of 2009 and September of 2013, by two endourologists. These cases were reviewed retrospectively.
Results: Among the nine procedures, we were able to address the stone(s) endoscopically… More >

Abstract Introduction: To assess bothersome results of surgery and changes in quality of life (QoL) in patients with two-staged urethral reconstruction. In patients requiring two-staged urethroplasty a functional corpus spongiosum is usually absent, and complications such as urinary dribbling, ejaculation problems and penile deviation can be expected. Data on these complications, patient satisfaction and QoL is limited.
Materials and methods: Retrospective analysis by chart review and a standardized questionnaire of 19 consecutive patients with urethral strictures treated by two-staged urethroplasty with buccal-mucosa-graft or mesh-graft.
Results: Overall success rate was 84%. Mean follow up 11.2 months, mean length… More >

Abstract Introduction: The prevalence of pelvic floor disorders (PFD) in aging women is comparable to the prevalence of erectile dysfunction (ED) in aging men. The objective of this study was to assess young adults' familiarity with the definition, prevalence, etiology, and treatment of PFD and ED.
Materials and methods: Women and men aged 18-40 years completed a validated survey (Prolapse and Incontinence Knowledge Quiz) to assess knowledge of urinary incontinence (UI) and pelvic organ prolapse (POP). Both groups completed a similar questionnaire created to assess knowledge of ED. Participants were asked to estimate the prevalence of these… More >

Abstract Introduction: Predicting patient survival rates following radical prostatectomy remains an area of clinical interest. We compared the ability of standard clinical Gleason scores and alternative 'weighted' Gleason scores to predict pathology, margin status and recurrence in prostate cancer.
Materials and methods: Patients who underwent robotic radical prostatectomy performed by a single surgeon between Jan 2007 - Dec 2008 were included. Tumor at the inked margin in pathologic samples was considered a positive margin. Recurrence was defined as PSA ≥ 0.2 or the institution of salvage therapy. Standard pathologic Gleason scores were recorded. The proportion of tumor… More >

Abstract Introduction: To assess the impact of statin use on biochemical recurrence (BCR) of prostate cancer after radical prostatectomy (RP).
Materials and methods: Data from all men treated with robot-assisted laparoscopic RP (RALRP) for localized prostate cancer between 2009 and 2014 at our institution were prospectively collected: age, body mass index (BMI), statin-use status, preoperative prostate-specific antigen (PSA) level, clinical T stage, biopsy Gleason score (bGS), D'Amico risk group, pathological T stage, specimen Gleason score (sGS), multifocality, perineural invasion, positive surgical margins and time to BCR. Univariate and multivariate analysis were performed to test associations between statin… More >

Abstract Introduction: Hemorrhage induced by prostate biopsy can interfere with the interpretation of prostate magnetic resonance imaging (MRI).
Materials and methods: We reviewed 101 patients who had prostate multiparametric MRI (MP-MRI) and radical prostatectomy.
Results: On MRI obtained within 4 weeks following the biopsy, hemorrhage was seen in 26/36 (72.2%) patients. Patients having a MRI between 4-6 weeks of the biopsy had hemorrhage in 8/14 (57.1%) cases. After 6 weeks, hemorrhage was less common but still present in 24/46 (52%) patients. There were five patients who had prostate MRI prior to biopsy and served as a control… More >

Abstract Introduction: To evaluate the potential significance of cystoscopy findings following neoadjuvant chemotherapy (NAC) as prognostic indicator in patients undergoing radical cystectomy for muscle-invasive bladder cancer (MIBC).
Materials and methods: Patients who received NAC prior to radical cystectomy for MIBC were analyzed. Patients were divided into two groups according to cystoscopy performed after two cycles of NAC: responders and non-responders. Univariate analysis was performed to analyze associations between observed response to chemotherapy and pT stage, pN stage and tumor downstaging. Logistic regression modeling was fitted to evaluate predictors for extravesical disease and pathologic downstaging. Kaplan-Meier analysis was… More >

Abstract Introduction: Overactive bladder (OAB) syndrome is a special condition characterized by urgency, with or without urinary urge incontinence (UUI), associated to frequency and nocturia, with important consequences on patients' quality of life (QoL). Administered as intradetrusor injections, botulinum neurotoxin type A (BoNT/A) is a new, promising, minimally invasive treatment option for OAB patients, non-compliant to conventional antimuscarinics. The aim of our study was to perform a systematic review of the literature concerning the efficiency and safety of different BoNT/A products in the treatment of OAB.
Materials and methods: A thorough PubMed search was performed. After having… More >
