Operative method, course and complications were analyzed retrospectively in 140 patients who underwent a conservative operation for renal tumor between June 1969 and December 1990. In 53 patients (20 women and 33 men, mean age 61.2 years, range 38 to 77 years, with 49 renal cell carcinomas and 4 benign renal tumors) there was an imperative indication for an(More)
BACKGROUND Urethral dilation has been recommended to treat voiding dysfunction that may occur after placement of tension-free vaginal tape (TVT) for the treatment of stress urinary incontinence. We report on a case of urethral erosion by the tape secondary to repetitive urethral dilations after surgery. CASE A urethral erosion by the tape was diagnosed by(More)
A low pressure rectosigmoid reservoir for urine is created obviating the need for colostomy, augmentation or extensive bowel surgery. Antimesenteric splitting of the intestine at the rectosigmoid junction and subsequent side-to-side anastomosis are performed. Urodynamic data demonstrate that the detubularization is effective in rendering high pressure bowel(More)
The structure of the extracellular, three-domain poliovirus receptor (CD155) complexed with poliovirus (serotype 1) has been determined to 22-A resolution by means of cryo-electron microscopy and three-dimensional image-reconstruction techniques. Density corresponding to the receptor was isolated in a difference electron density map and fitted with known(More)
OBJECTIVES i) To evaluate objective response, toxicity, and quality of life (QoL) of gemcitabine monotherapy as second-line treatment in patients with cisplatin-refractory, metastatic transitional cell carcinoma (TCC). ii) To assess prognostic parameters for response to treatment and for improvement of QoL parameters. PATIENTS AND METHODS 30 patients were(More)
BACKGROUND The clinical Stage I of nonseminomatous germ cell tumors (NSGCT) is inaccurate in 30% of patients. In previous studies on tumor biologic risk factors, low tumor proliferation rates predicted a group of patients at low risk for occult metastatic disease. The goal of this study was to confirm the immunohistochemical assessment of tumor(More)
PURPOSE A retrospective analysis was done of long-term results of internal urethrotomy to evaluate risk factors of stricture recurrence. MATERIALS AND METHODS Followup studies were performed of 937 patients with urethral strictures treated with internal urethrotomy. Of the patients 357 were treated at Mainz University between 1977 and 1989 (mean followup(More)
Autologous buccal mucosa as a substitute for urethral epithelium was studied in 2 dogs and used in 6 patients with difficult urethral reconstruction problems. The indications for an operation in these patients were failed hypospadias repairs with limited skin in 3, severe structure disease after hypospadias repair in 1, a short urethra in 1 and epispadias(More)
Using a strategy developed by R. Andino, D. Silvera, S. D. Suggett, P. I. Achacoso, C. J. Miller, D. Baltimore, and M. B. Feinberg (Science 265:1448-1451, 1994), we constructed recombinant polioviruses by fusing the open reading frame (ORF) of the green fluorescent protein gene (gfp) of Aequorea victoria or the gag gene (encoding p17-p24) of human(More)
OBJECTIVES Epigenetic events such as promoter hypermethylation have been implicated in prostate carcinogenesis. We present a real-time, methylation specific protocol to detect hypermethylation in the promoter region of the GSTP1 gene in benign hyperplasia and adenocarcinoma of the prostate. METHODS In our preliminary study, 31 prostate cancer and 5 benign(More)
