Testicular sperm extraction (TESE), together with intracytoplasmic sperm injection, has become the treatment of choice for patients with nonobstructive azoospermia related to nonmosaic Klinefelter syndrome (KS) who want to father children. However, predicting successful microdissection TESE for patients with KS remains controversial. Thus, we conducted a study to determine whether the prediction of...
Urologic trauma produced by dog bites is uncommon. Several previous single reports and small case series have described the treatment of dog bite-induced injuries to the external genitalia. In this report, we describe our treatment of a patient with thoracic paraplegia and an ileal conduit who had extensive trauma to his ileostomy as a result of a bite by the family dog. To our knowledge, the current...
Fibroepithelial polyps of the ureter are rare benign mesothelial tumors. Most polyps are small; however, very rare large polyps have also been reported. Currently, most investigators encourage endoscopic management in these patients. Nevertheless, endoscopic resection can be difficult in patients with a long or large polypoid lesion. We describe our experience and laparoscopic technique for treatment...
To retrospectively assess the usefulness of the measurements on preoperative computed tomography (CT) of patients with urinary stone disease for planning the access site using vertical angulation of the C-arm.Of the patients who underwent percutaneous nephrolithotomy from November 2001 to October 2006, 41 patients with superior calix access had undergone preoperative CT. The depth of the target stone...
Lipoblastoma of the scrotum is a rare clinical entity in children. It represents one of several differential diagnoses of scrotal masses that include malignant tumors. Surgical extirpation is mandatory. We present a rare case.
Inflammatory myofibroblastic tumors are rare, locally invasive tumors that can involve the genitourinary tract. Therapy has consisted primarily of surgery, and anecdotal experience using both chemotherapy and radiotherapy, which have yielded unimpressive results. We report the first case of a bladder inflammatory myofibroblastic tumor that responded to an anti-inflammatory regimen (prednisone and...
We recently described a novel, energy-free technique of nerve-sparing laparoscopic radical prostatectomy performed with transrectal ultrasound guidance. We provide our current technique and updated experience with 169 patients and report the potency outcomes of this energy-free, clip-free, bioadhesive-free, nerve-sparing laparoscopic radical prostatectomy.Our technique involves transient bulldog clamping...
Tumors reminiscent of müllerian epithelial tumors of the ovary have been reported outside of the ovary, including in the pancreas and paratesticular region. The latter are most commonly serous tumors of borderline malignant potential and involve the tunicae. We present the first case of a serous cystadenoma of the epididymis in English reports with a brief literature review.
The sensitivity of voided urinary cytology has been reported as very low. In this study, we investigated the sensitivity and clinical utility of voided urinary cytology in the detection of various grades and stages of transitional cell carcinoma (TCC) of the bladder compared with the urinary nuclear matrix protein-22 (NMP-22) qualitative assay.From March 2004 to April 2006, all patients with TCC of...
Inflatable penile prosthesis (IPP) infection remains a devastating surgical complication. American Medical Systems recently introduced an IPP with a coating of minocycline HCL and rifampin (InhibiZone). We report our experience with this coating and compare the rate of infection with our historical rate.A total of 467 patients receiving InhibiZone-coated IPPs were followed up for infection. The patients...
Renal access is the most crucial step in the performance of percutaneous nephrolithotomy and is a difficult skill to acquire for novice surgeons. We report on a simple fluoroscopic technique based on the laser positioning device that emits an aiming beam common to modern fluoroscopy C-arm units.
Prostatic calcification is common in asymptomatic elderly men. However, young men with chronic pelvic pain syndrome (CPPS) often have significantly calcified prostates. We studied the incidence and significance of prostatic calcification in men with CPPS.From July 2005 to August 2006, 130 new patients with CPPS were seen at our clinic. Of these 130 patients, 47 underwent transrectal ultrasonography...
The reference standard treatment for transitional cell carcinoma (TCC) of the upper tract remains nephroureterectomy. However, with improvements in endoscopic technology and techniques, endoscopic ablation of upper tract TCC has become a reality for highly selected patients. We report our present technique and 16-year experience of office-based ureteroscopy for surveillance of TCC after initial endoscopic...
To define the temperature-time points that result in cell death in a human renal cell carcinoma cell (RCC) line in vitro.Cellular viability and clonogenic cell survival were determined for human A498 RCC cells after thermal treatment. Various temperature (45°C to 70°C) and time (1 to 30 minutes) combinations were used. Cell viability was assessed by vital dye uptake and clonogenic cell survival. Mathematical...
To evaluate whether the clinical grade predicts the final pathologic stage in upper urinary tract transitional cell carcinoma.We retrospectively reviewed the records of 184 consecutive patients undergoing nephroureterectomy for upper urinary tract transitional cell carcinoma at our institution from 1986 to 2004. Their clinical, surgical, and pathologic data were reviewed to determine the positive...
To update our previously published nomogram predicting for biochemical outcome with 10-year data from a larger cohort of patients treated with three-dimensional conformal radiotherapy (RT) or intensity-modulated RT for localized prostate cancer.From 1988 to 2004, 2253 patients were treated with three-dimensional conformal RT or intensity-modulated RT for clinical Stage T1-T3 prostate cancer. Prescription...
The warm ischemia time of tissue before fixation for pathologic analysis has been linked to changes in cell morphology and nucleic acid and protein integrity. Robotic-assisted laparoscopic prostatectomy (RALP) results in longer warm ischemia times than open radical retropubic prostatectomy. To assess the effect of longer ischemia times on biomolecular integrity, we analyzed DNA, RNA and protein collected...
