Ejaculatory duct obstructions are diagnosed in approximately 5% of azoospermic men and can be treated by transurethral resection (TURED) or incision of the ducts. Eight patients with azoospermia and ejaculatory duct obstructions were treated by TURED after clinical examination, semen analysis, biochemical analysis of seminal plasma, endocrine analysis,(More)
OBJECTIVES Stricture of the vesico-urethral anastomosis is a well-known complication after radical prostatectomy. Dilatation, stricture incision or resection have been proposed for endoscopic treatment. METHODS In a retrospective study of 340 patients with prostatic cancer who underwent a radical retropubic prostatectomy from 1988 until 1996, we looked at(More)
OBJECTIVE To reduce the incidence of postoperative palpable induration after treating congenital penile curvature, using a modified corporoplasty technique. PATIENTS AND METHODS In a retrospective unrandomized clinical trial, 105 patients with a congenital penile angulation of >30 degrees and for whom coitus was therefore difficult or impossible,(More)
Incidence, extent, and time of seed loss after retropubic I-125 implantation was assessed in 52 patients treated for prostatic carcinoma. Radiographic controls up to 62 months were done to evaluate losses. Ninety percent of all patients lost seeds, averaging 8% of total implant number. Loss most frequently occurred within the first month by transurethral(More)
In urology, catheter-associated urinary tract infections are most common, and postoperative wound infections the second most common nosocomial infections. This article gives an overview of standard hygiene measures, but focuses on proven and unproven hygiene measures for preventing catheter-associated urinary tract infections and postoperative wound(More)
In the past decade, subureteric endoscopic injection of Teflon or collagen has been propagated as a safe and successful treatment for vesicoureteral reflux. In our center, from 1990 through 1995, 118 children and 5 adults with reflux and recurrent urinary tract infections were injected with cross-linked bovine collagen in an open, prospective study.(More)
Indications for preoperative and palliative embolization of renal tumors have been restricted due to the failures caused by insufficient tumor blockage. Personal experiences using a variety of materials (balloon n = 18, gelfoam n = 10, ethibloc1 /glucose n = 23) and their effectiveness are presented. special emphasis is placed on the influence of parasitic(More)
In the Department of Urology, University of Freiburg, West Germany extracorporeal piezoelectric shock wave lithotripsy (EPL) has been used in the treatment of urinary and biliary stones since November 1987. The first 85 treatments (in 71 patients) for renal stones were evaluated with regard to complications and side effects. There was no need for any(More)
A series of 65 consecutive patients with suspected venous leakage as a cause of their erectile dysfunction underwent dynamic and pharmacocavernometry/cavernography. This comparison of methods for diagnosing venous leakage produced divergent findings in 25/65 patients (38.5%). Because of its theoretical advantages, pharmacocavernometry/cavernography is(More)
Vaccination with gene-transfected tumor cells has recently been proposed as a new strategy in the immunotherapy of cancer. Since autologous tumor cells provide an optimal antigen profile, the possibility of generating single cell suspensions from renal cell carcinoma (RCC), malignant melanoma (MM), colon carcinoma (CC), and non-small-cell lung cancer(More)
