Abstract Introduction: Treatment for localized prostate cancer (LPC) may not improve survival and commonly impairs health related quality of life. National guidelines provide algorithms to choose between treatment or observation for LPC, but the algorithms require the factoring of the patient's baseline comorbidity adjusted life expectancy (CALE). However, no method is available to estimate CALE of 10 or more years.
Materials and methods: A mailed survey was completed by newly diagnosed untreated LPC patients. Their baseline CALE was estimated by weighting their age based life expectancy by quartiles of comorbidity scores, and a national guideline was used to… More >

Abstract Introduction: Measurements of prostate size are obtained to contribute in the diagnosis and follow up of patients with a variety of diseases. Since its introduction, transrectal ultrasonography (TRUS) of the prostate has become the most common method for assessment of prostate volumes. Ultrasonography, in general, has been associated with concerns of operator dependent variability. Herein, we analyze the accuracy of urologists and radiologists performing TRUS.
Material and methods: The accuracy of preoperative TRUS prostate volume estimation was evaluated by comparing it to gross specimen prostate weight following robot-assisted radical prostatectomy (RARP) performed from August 2004 to March… More >

Abstract Objectives: Studies have suggested that pathology of the lower urinary tract can be detected by following changes in urinary proteins. We evaluated urine nerve growth factor (NGF) levels from patients with a variety of urologic conditions to examine NGF's role as a future biomarker.
Materials and methods: Urine samples were obtained from 72 patients with normal non-diseased urinary tracts (n=13), neurogenic overactive bladder (NOAB) (n=13), idiopathic overactive bladder (OAB) (n=17), interstitial cystitis/painful bladder syndrome (IC/PBS) (n=8), prostate cancer (n=7), history of prostate cancer status post robot-assisted laparoscopic prostatectomy (RALP) (n=6), active bladder cancer (n=4), and nephrolithiasis (n=4).… More >

Abstract Aims: The assessment of incontinence therapies is complicated by the variety of patient reported outcomes (PRO) measures used in research protocol. Patient satisfaction may be one of the most relevant albeit complex PRO measures and is a function of many related variables. We sought to assess the relationship between patient satisfaction and other PRO.
Methods: A retrospective review of patients undergoing SPARC (n = 314) and autologous rectus pubovaginal sling (PVS) (n = 127) was performed, with 204 (SPARC) and 67 (PVS) patients completing questionnaire surveillance and minimum 12 month follow up. Outcomes were assessed using validated… More >

Abstract Purpose: Robot-assisted radical cystectomy (RARC) is an alternative approach for treatment of bladder cancer. We provide a critical review of the current status of RARC and pelvic lymph node dissection with a focus on feasibility, safety and oncological efficacy of the procedure.
Materials and methods: The PubMed literature database was reviewed for RARC series that have been reported in the English language until the present time. Surgical technique, operative parameters, pathologic outcome, complications and quality of life were examined.
Results: RARC is progressing steadily. With nearly 500 published cases worldwide, RARC proves to be technically feasible and oncologically More >

Abstract Purpose: To compare operative parameters and outcomes in 30 cases of robotic pyeloplasty (RP) versus 30 cases of laparoscopic pyeloplasty (LP), performed by a single surgeon, for ureteropelvic junction (UPJ) obstruction.
Methods: Patients with primary UPJ obstruction were included in the study. The same surgeon (AKH) performed RP (usually using a transperitoneal Anderson-Hynes technique) on 30 patients in Group I and employed LP on 30 patients in Group II, in a nonrandomized fashion. The patients were followed for 18 months postoperatively. Three robotic and one assistant port were required in Group I, and 3 or 4 ports… More >

Abstract Objective: Wine is one of the oldest documented medicinal remedies, dating back thousands of years. We explore the medicinal uses of wine, with a focus on the treatment of genitourinary disease, beginning in ancient Egypt, India, and Israel, and then moving forward to include Greek, Roman, and Arabic medicine. Our review continues into the Middle Ages and renaissance, and finally evaluates the medicinal properties of wine as we understand them in our current scientific paradigm and its specific application to urology.
Methods: A review of the literature was completed, reviewing the medical theories and medicinal uses of… More >

Abstract Summary: We describe two patients who underwent bilateral epididymovasostomy and subsequent percutaneous epididymal sperm aspiration (PESA) because of persistent azoospermia, after which sperm returned to the ejaculates of both patients, resulting in an unexpected natural pregnancy in one of the couples.
Patients: Two men, Patient A (age 35 years) and Patient B (age 37 years), underwent vasectomy reversal 8 and 9 years following vasectomies, respectively. In both cases, bilateral epididymovasostomy was required due to epididymal obstruction. Semen analysis was performed at 3 month intervals following the procedure. Both patients underwent PESA, and one couple completed intracytoplasmic sperm… More >

Abstract A 54-year-old Caucasian male presented to our emergency department because he had self-inserted a transparent plastic and flexible tube into the urethral meatus, during erotic games. A plain pelvic x-ray film and an abdominal ultrasound were executed to determine the size, shape, orientation and location of the foreign body, and any eventually associated visceral injuries or complications. As results, a long tube of about 50 cm was described entering the urethra and reaching the bladder cavity in which the tube was folded and wrapped, in absence of any visceral complication. The patient underwent an urgent… More >

Abstract This article describes an unusual fi nding in a patient who presented with an adenocarcinoma of the prostate and right hydronephrosis. A 68-year-old male presented with right hydronephrosis and a PSA of 96. DRE was consistent with cT3 carcinoma. Cystoscopy showed an exophytic superfi cial transitional cell carcinoma (TCC) of the bladder and a transrectal biopsy of the prostate confi rmed adenocarcinoma Gleason score 4+3. Staging investigations (CT pelvis and bone scan) were negative; androgen deprivation therapy was therefore initiated for the prostatic adenocarcinoma. Upper tract imaging showed multiple fi lling defects in the proximal… More >

Abstract Carcinoma metastatic to the prostate occurs rarely and is most commonly associated with malignant bladder neoplasms. We present the case of a 73-year-old male with a history of gastroesophageal adenocarcinoma and clinically symptomatic benign prostatic hyperplasia who underwent photoselective vaporization of the prostate and presented several months later with gross hematuria, intermittent urinary retention and bilateral ureteral obstruction causing acute renal failure. After relieving the ureteral obstruction, subsequent transurethral resection of the prostate revealed locally invasive metastatic esophageal adenocarcinoma. To our knowledge, this is the fi rst reported case of metastatic gastroesophageal carcinoma to the More >

Abstract Aggressive fibromatosis or desmoid tumor is a histologically benign entity with unknown etiology that may present a serious clinical course. Due to its high tendency to recur and local aggressive behavior, and as there is no established effective medical treatment, complete surgical excision remains the sole management. To our knowledge, we describe the first case of giant desmoid tumor which arose from ileal neobladder mesenterium in a bladder cancer patient with orthotopic substitution. More >

Abstract Introduction: Postoperative radiotherapy after radical prostatectomy has been shown to improve numerous outcomes for selected patients in mature randomized controlled trials. During treatment patients usually experience mild to moderate urinary symptoms, lower gastrointestinal symptoms and tiredness. We describe an unusual case of a patient experiencing severe, culture negative urinary symptoms early in a course of salvage radiotherapy.
Materials and methods: A patient's history was retrospectively derived from a single institution.
Results: A total radiation dosage of 66 Gy in 33 fractions was to be delivered to the prostate bed by intensity modulated radiation therapy. Urinary symptoms consisting of More >
