To evaluate the relationship between the lengths of 2 regions of the intraprostatic urethral sphincter, the distal region (from the apex to the adenoma [AA]) and the proximal region (from the adenoma to the verumontanum [AV]) and prostate volume (PV) in patients with clinical benign prostate hyperplasia.A total of 110 patients who underwent magnetic resonance imaging before holmium laser enucleation...
Fracture of the penis is a well-recognized yet relatively uncommon urologic event. Forceful, blunt trauma with lateral bending of the penis in an erect state typically results in a transverse rupture of the tunica albuginea of the corpus cavernosum. Longitudinal tears of the corpus cavernosum are by themselves considered infrequent. We present a rare case of a patient with longitudinal rupture of...
To elucidate the trends in urologic causes for renal transplant in the pediatric population using a national database. Little is known about the specific pediatric urologic conditions and resultant trends that precede renal transplantation.We reviewed the United Network for Organ Sharing (UNOS) database for pediatric patients (<18 years old) who underwent renal transplantation from January 1988...
Risperidone is commonly prescribed by pediatricians for a variety of behavioral and psychological disorders. We report a boy with autism-spectrum disorder, who developed frequent penile erections after an increase in risperidone dosage for a month. The patient fully recovered 2 days after risperidone discontinuation. This report concerns the youngest case of psychotropic medication-induced sexual...
To identify metabolites that are associated with an overactive bladder (OAB) using metabolomics.A total of 58 male patients without apparent neurologic disease completed 24-hour bladder diaries of their micturition behavior and International Prostate Symptom Score (IPSS) for the assessment of micturition behavior and lower urinary tract symptoms. Urgency was defined as an IPSS urgency score of ≥2...
To use the Truven Health MarketScan database to better approximate the annual rate of vasectomies performed in the US population, to determine changes over time, regional differences, providers performing this, and to know if there is any monthly variation in vasectomy rates.Claims data were evaluated from 2007 to 2015 to determine the annual prevalence of vasectomy by patient age and region in the...
To investigate the role of renal resistive index (RI) and pulsatile index levels measured with renal Doppler ultrasonography in predicting the success of medical expulsive treatment in patients with ureteral stones.Patients admitted to our clinic between January and December 2017 with a ureteral stone of less than 1 cm in diameter were evaluated in terms of their RI and pulsatile index values obtained...
To describe our surgical technique for robotic partial nephrectomy,1 focusing on specific technical hints for vascular clamping on patients with renal masses and endovascular stent (ES) in the renal artery.We reviewed the records of 3 patients that underwent robotic partial nephrectomy in our institution with precise clamping of renal arteries due to previous placement of ES. Perioperative outcomes...
To investigate whether prostate cancer screening with prostate-specific antigen (PSA) is beneficial in reducing prostate cancer mortality, and to determine optimal screening intervals and age groups to be screened.This is a retrospective cohort study of 400,887 men under age 80, with no history of prostate cancer, who had PSA testing at Kaiser Permanente Northern California in the 5 calendar years...
To determine if intradetrusor injection of onabotulinumtoxin-A (BTX-A) would reduce postoperative narcotic and anticholinergic requirements in children undergoing open continent bladder reconstruction.After institutional review board approval, we retrospectively reviewed all bladder reconstructions performed. Bladder reconstruction was defined as the following procedures in any combination: bladder...
To report the prevalence of low serum testosterone (LST) in men undergoing artificial urinary sphincter (AUS) placement at a single high-volume institution.We retrospectively reviewed all men undergoing AUS procedures by a single surgeon from January 2015 to January 2018 to identify men with pretreatment total serum testosterone levels. LST was defined as less than 280 ng/dL. Patients with only posttreatment...
To evaluate the effects of different degrees of intratesticular hematoma (ITH), a major consequence of blunt testis trauma, on testis microstructure and function. We determined a cutoff point for significant vs nonsignificant ITH.Seventy male rats were divided into 7 equal groups. The control group remained intact. Sham groups consisted of rats given an intratesticular injection of normal saline in...
To compare intraoperative and 1-hour postoperative outcomes in caudal vs dorsal penile nerve block (DPNB) patients undergoing penile surgeries.We performed a retrospective cohort study of boys <10 years old undergoing penile procedures (2013-2015) using the Pediatric Regional Anesthesia Network, Pediatric Health Information System databases, and our medical records. The primary outcome was a maximum...
