Abstract Overactive bladder is a common urological diagnosis, which is often untreated as patients fail to seek help for this embarrassing problem. This disorder causes significant lifestyle limitations for the patient and is also expensive as it reduces national productivity and therefore affected patients should be treated. It is simple for primary care providers to make a working diagnosis in this disorder and they should be carrying out simple investigations in order to make the diagnosis. Commencement of therapy should start with conservative measures such as lifestyle modifications including pelvic floor exercises and bladder drill followed… More >

Abstract Objectives: To correlate the measured dimensions of urinary stones from spiral non-contrast computerized tomography (CT) with that of plain radiography (KUB).
Methods: The transverse diameter as reported on CT was compared to the measured transverse diameter on KUB for 61 stones. The transverse and craniocaudal dimensions on CT were then re-measured for 30 urinary stones and again compared to the re-measured values for KUB. The craniocaudal dimension on CT was determined by measuring the stone on reconstructed coronal CT images. Measurements between imaging modalities were blinded and performed consecutively by a dedicated investigator.
Results: The mean transverse… More >

Abstract Introduction: Urinary obstruction (UO) or failure to void has been observed during several episodes of short-duration spaceflight, necessitating bladder catheterization. It should be considered a possible medical condition in long-duration space missions as well. Antiemetics used early in space flight add to the risk and severity of voiding problems, along with the sensory and psychological peculiarities of voiding without gravity and in the unusual setting of a spacecraft. Urolithiasis due to the above-normal calcium excretion increases the risk of UO in long duration space missions. Finally, the individual risk of UO is higher against the background… More >

Abstract Introduction: Robotic-assisted laparoscopic radical prostatectomy (RLRP) is playing an increasing role in the surgical management of prostate cancer. The benefits of minimally invasive surgery, enhanced surgeon familiarity with the instrumentation, and increased patient demand has led to the popularity of this surgical technique. There are, however, shortcomings specifically associated with this technology. Notably, instrumentation failure associated with robotic procedures represents a new and unique problem in urological surgery. We examine the rate of mechanical failure of the da Vinci robotic system and its impact on our prostate cancer program.
Materials and methods: We reviewed our prospective, institutional… More >

Abstract The general consensus about prostatic duct adenocarcinomas is that they have a rather aggressive biological behavior. In addition, studies or reports of latent adenocarcinoma of the prostatic duct in necropsy material are scarce in the literature. We report here three cases of adenocarcinoma of the prostatic duct that were found incidentally among 39 cases of latent acinar prostate adenocarcinomas in necropsy material. We examined the morphologic and histological features of these prostatic duct adenocarcinomas, in order to better understand their biological behavior. We identified two cases of mixed ductal-acinar adenocarcinoma and one case of pure More >

Abstract We report the first case, to our knowledge, of xanthogranulomatous pyelonephritis (XGP) with psoas abscess occurring during pregnancy. A 37-year-old woman in the third trimester of pregnancy presented with low back pain and a fever. From sonographic features, a multidisciplinary team decided to perform computed tomography of the abdomen with contrast agent injection, which strongly suggested diffuse XGP of the left kidney with a psoas abscess. Cesarean section at 32 weeks was followed by extended nephrectomy. Pathological examination of the operative specimen confirmed the diagnosis. Outcomes were favorable in the mother and baby. The diagnosis More >

Abstract Introduction: Malignant mesothelioma involving the tunica vaginalis is an extremely rare tumor.
Case: We describe a case of a 39-year-old man who initially presented with discomfort in the left testis and underwent resection of a hydrocele in the left testis. A pathology examination of a frozen section of a lesion on the tunica identified the lesion as mesothelioma, which was confirmed by a second pathology examination. No metastatic disease was found. The patient subsequently underwent a left radical orchiectomy and a partial scrotectomy, and has been disease free for 7 years.
Discussion: The first case of malignant More >

Abstract Adrenocortical carcinoma can have a clinical presentation that mimics a primary renal tumor. We describe a case of a 47-year-old male who presented with flank pain, weight loss, and a 14 cm mass arising from the upper pole of the right kidney on imaging. Upon surgical resection he was found to have a 1500 gram stage II adrenocortical carcinoma. The clinical features, pathologic findings, grading criteria, and differential diagnosis of adrenocortical carcinoma are reviewed. More >

Abstract Bacillus Calmette-Guerin (BCG) is a common intravesical agent utilized for superficial transitional cell carcinoma of the bladder. The potential for side effects and complications does exist secondary to the utilization of live attenuated bacteria. We present the case of a 70- year old male that developed BCG pyelonephritis and associated renal mass following the fifth of six weekly intravesical BCG therapies. The patient improved clinically and renal mass resolved following 3 months of isoniazid monotherapy without renal biopsy. More >

Abstract We present the case of a 78-year-old male who presented to clinic for follow-up of a papillary transitional cell carcinoma of the urinary bladder. Notably, the patient also had a history of colorectal resection for an adenocarcinoma. The follow-up appointment revealed left hydronephrosis with evidence of a distal ureteric stricture. Cytology and biopsy from the ureter subsequently disclosed the presence of malignant cells that were originally thought to be of urothelial origin. Upon surgical resection the lesion was found to be an adenocarcinoma, morphologically consistent with a metastasis from the patient’s primary colonic adenocarcinoma. This More >
