Male slings for postprostatectomy incontinence.
We have used a wide cadaveric fascial or dermal sling placed at the proximal bulbar urethra. Using an entirely perineal approach, the sling ends are fixated to the inferior pubic rami using bone anchors. Of 9 patients with bladder neck slings, 6 are dry, 1 is significantly improved, and 2 have faile...
Aspects on transurethral microwave thermotherapy of benign prostatic hyperplasia.
The underlying principle behind new minimal invasive procedures, such as microwave thermotherapy, is to coagulate the prostatic adenomatous tissue by means of heat. This article describes the action of heat on tissue and identifies areas of concern during treatment. The extent of the necrosis during...
Use of artificial neural networks in the clinical staging of prostate cancer: implications for prostate brachytherapy.
This review describes two studies to evaluate artificial neural networks (ANNs) in prostate cancer staging. In the first study, an ANN was trained to identify prostate cancer patients at low risk of lymph node spread (LNS). The second study evaluated an ANN to predict capsular penetration (CP) in me...
Right intrathoracic renal ectopia: a case report and review of the literature.
We report a case of right intrathoracic renal ectopia associated with a previously unreported congenital anomaly (trisomy 21) and review of the literature.
Transrectal puncture and drainage of seminal vesicle abscess.
Seminal vesical abscesses are extremely rare. We report a case in which successful treatment was achieved using a minimally invasive transrectal approach.
Determination of serum creatinine prior to iodinated contrast media: is it necessary in all patients?
The risk of contrast-associated nephrotoxicity (CAN) is increased in the presence of preexisting renal disease. Although routine determination of serum creatinine (Cr) prior to imaging studies is the traditional method of assessing renal function, it is a costly and time-consuming practice. The purp...
Ureteroscopic treatment of symptomatic caliceal diverticular calculi.
Renal calculi that reside in caliceal diverticula are difficult to treat. Numerous treatment modalities have been used, including extracorporeal shock wave lithotripsy, laparoscopy, and percutaneous treatment. All therapies directed at fragmenting the stones are limited by the ability of these fragm...
Color Doppler sonography of the prostate.
The digital rectal exam (DRE), serum prostate specific antigen (PSA) level and transrectal ultrasound (TRUS) serve as the primary means of early detection of prostate cancer, but all have known limitations. Because of the low predictive value for the gray scale detection of prostate cancer with TRUS...
Creation of the LeBag orthotopic bladder using absorbable staples.
Absorbable stapling devices have been described by several groups for the creation of continent urinary diversions. Experience with these devices in the creation of the LeBag ileocecal orthotopic pouch is described. Use of the staplers simplifies pouch construction and yields functional results simi...
Therapeutic laparoscopy for the nonpalpable testicle.
We describe our technique of laparoscopy and laparoscopically assisted orchidopexy. Our early results in 24 patients with nonpalpable intraabdominal testes have encouraged us to recommend this option as the procedure of choice....
