Unilateral Papillary Cystadenoma of the Epididymis as A First Presentation of Von Hippel-Lindau Disease.
Association between papillary cystadenoma of the epididymis (PCE) and Von Hippel-Lindau Disease (VHLD) is well known and stronger for bilateral tumours. Unilateral PCE occurs either as a sporadic tumor without evidence of VHLD or in the context of a known diagnosis of VHLD, indeed it has never been reported as the first manifestation of VHLD. In contrast we report the case of a boy with an apparently isolated, unilateral PCE, that resulted to be the first manifestation of an unknown VHLD. Thus we recommend screening for VHLD in patients with a new diagnosis of unilateral PCE, especially if young.
Anastomotic stricture is a relatively common complication of the urinary diversion that accompanies radical cystectomy. Management options range from endoscopic procedures to open surgeries, with a subset of the latter employing bowel as the interposing segment. In this report, we describe a rare patient, who successfully underwent a “Reverse 7” procedure, bypassing strictures at both anastomotic junctions between ureters and neobladder.
To evaluate the paternity rate in a large cohort of asymptomatic adult varicocele patients undergoing non-surgical management and surgery.
Huang J, Xie D, Xiong R, Et Al. the Application of Suctioning Flexible Ureteroscopy with Intelligent Pressure Control in Treating Upper Urinary Tract Calculi on Patients with a Solitary Kidney. Urology. 2018;111:44-47., https://doi.org/10.1016/J...
We read the article by Huang et al. 1 with great interest, which they suggested to use a novel intelligent pressure-controlled flexible ureterorenoscope (fURS) for stone treatment in solitary kidneys. Being novel equipment, it might open new horizons in renal stone management. As is known, stone volume, stone location and increased intrarenal pressure during operation are some of the most important factors that reduce fURS success and effectiveness. Increased intrarenal pressure is also associated with various complications such as septic complications and hemorrhage 2, 3.
Predictor Role of Pre-Treatment Resistive and Pulsatile Indexes in Success of Medical Expulsive Therapy of Ureteral Stones
To investigate the role of renal resistive and pulsatile index levels measured with renal Doppler ultrasonography in predicting the success of medical expulsive treatment in patients with ureteral stones.
To demonstrate the technique and the outcomes of robot assisted Y-V plasty bladder neck reconstruction (RYVBNR).
Intra-Operative Onabotunlinumtoxin-A Reduces Post-Operative Narcotic and Anticholinergic Requirements after Continent Bladder Reconstruction
To determine if intra-detrusor injection of Onobotulinumtoxin-A (BTX-A) would reduce post-operative narcotic and anticholinergic requirements in children undergoing open continent bladder reconstruction.
The mechanism of the male transobturator sling (TOS) for postprostatectomy urinary incontinence up to now had been debated and unproven. We originally believed that there were urethral “anatomical or urethral length” changes as well as “functional or mobility” changes following sling placement. Our theory for why men leaked prior to conducting this study included hypermobility, similar to the mechanism seen in females, as well as urethral length changes. In fact, this study has proven the null hypothesis for the hypermobility; mobility was not changed with the sling in the pre- and postintervention groups.
The authors present a study that attempts to shed light on the mechanism of action of the AdVance male transobturator sling (TOS) in achieving continence in incontinent men following both robotic – assisted and open radical prostatectomy. Their implied hypothesis is that lengthening of the membranous urethra at rest and at Valsalva is the most important factor and set out to show this by comparison of a group of TOS patients with a series of matched continent post prostatectomy men.
46 XY Denys-Drash Syndrome. Is There a Role for Nephron Sparing Modalities in Management of Renal Masses? A Report of Two Cases
Denys Drash Syndrome (DDS) is a combination of genital and urinary anomalies that mostly associated with renal and gonadal malignancies. We report 2 patients who presented with genital ambiguity and were diagnosed as 46XY DDS. Both patients had renal masses during follow up and underwent partial nephrectomy aiming to have transplant at older age.
Separating the Wheat From the Chaff: An Evaluation of Readability, Quality, and Accuracy of Online Health Information for Treatment of Peyronie's Disease
To characterize available information about Peyronie's disease online and evaluate its readability, quality, accuracy, and respective associations with HONcode certification and website category.
CD20-negative diffuse large B-cell lymphoma (DLBCL) is a very uncommon neoplasm and very rare unclassifiable cases that did not meet the criteria for well-established subtypes of CD20-negative DLBCLs have been reported. Often present an aggressive clinical course with important chemoresistance and poor prognosis. Here, we report a case of CD20-negative DLBCL presented as a testicular mass. To the best of our knowledge, this is one of the first reported cases of testicular unclassifiable CD20-negative DLBCL.
Duplex-Ultrasound Guided Direct Percutaneous Management of Pseudoaneurysm of Branch of Segmental Renal Artery: Technique and Its Outcome
To describe the role of Duplex-Ultrasound Imaging (DUI) in prompt diagnosis of pseudoaneurysm (PSA) of a branch of the segmental renal artery (b-SRA) and evaluate outcomes of DUI directed percutaneous embolization.
To further explore the issue of work parity between men and women urologists in the context of demographics, practice characteristics, subspecialty affiliation, and planned retirement.
PROMIS® Pain is Independent of Stone Burden and Predicts Surgical Intervention in Patients with Ureteral Stones
Patients with obstructing ureteral stones typically experience sudden onset, severe pain. We examine the National Institutes of Health’s Patient Reported Outcome Measurement Information System (PROMIS®) pain instruments in patients with acute ureteral stones.
Family history is under-estimated in children with isolated hypospadias: a French multicenter report of 88 families.
Whereas familial forms of complex disorders/differences of sex development have been widely reported, data regarding isolated hypospadias are sparse and a family history is thought to be less frequent. We aimed 1-to determine the frequency of hypospadias in families of hypospadiac boys 2-to determine if theses familial forms exhibit a particular phenotype 3-to evaluate the prevalence of genetic defects of the main candidate genes.A prospective inclusion of 395 hypospadiac boys screened for family history with a standardized questionnaire, extensive clinical description, family tree and sequencing of AR, SF1, SRD5A2 and MAMLD1 was performed.
Novel Observations of Female Genital Anatomy in Classic Bladder Exstrophy Using Three-Dimensional MRI Reconstruction
Understanding the distinct female anatomy in classic bladder exstrophy is crucial for optimal reconstructive and functional outcomes. This study presents novel quantitative anatomical data in females with classic bladder exstrophy prior to primary closure.
We would like to thank Dr. Albertsen for his comments, and we agree that understanding the theoretical and practical role of multiparametric prostate magnetic resonance imaging (mpMRI) in the setting of active surveillance is important. The active surveillance “roadmap” designed by the Michigan Urological Surgery Improvement Collaborative advocates 3 options to be performed within 6 months after initial biopsy in patients with known low-risk prostate cancer: repeat standard prostate biopsy, mpMRI, or genetic testing.
Urologists still debate the appropriate management of screen detected, clinically localized prostate cancer. The enthusiasm that accompanied Catalona's 1991 article that promoted prostate specific antigen (PSA) screening has given way to the more sobering reality that PSA screening results in many unnecessary biopsies and often leads to treatment of clinically insignificant disease.1,2 Results from the PROTECT trial show that only 1% of screen detected men succumb to prostate cancer within ten years of diagnosis.
Urine is normally warm because it comes from inside the body, which has a core temperature of 98.6°F. Hot urine occurs when urine is hotter than normal, such as during a fever, or when a person has a burning feeling while urinating. This is often caused by an infection, and the causes can differ between men and women.
