[Cases of Leydig cell tumor in male infertility].

1745 patients at the Department of Urology of Tenon Hospital (Paris, France) from 1990 to 2006 and at the department of urology of Tbilisi State Medical University (Georgia) during last several months have been examined and counseled on male infertility. Leydig cell tumor was found in 4 patients, among them 3 by palpation and testicle echography, fourth patient (at the age of 33) with bilateral varicocele (III stage at the left, II stage at the right) was more interesting for us. Leydig cell tumor was found out at the scrotum exploration.

[Prostate-specific antigen in serum and prostate epithelium in benign prostatic hyperplasia].

The aim of our investigation was the simultaneous study of concentration of prostate-specific antigen (PSA) in serum and its immune-histochemical expression in the adenomatous prostatic tissue. 50 patients have been investigated. In 48 patients benign prostatic hyperplasia (BPH) has been diagnosed, and 2 patients served as controls.

[Bilateral microsurgical varicocelectomy in infertile men].

Unlabelled: We assessed how bilateral microsurgical varicocelectomy alters semen quality in a large cohort of infertile men with bilateral varicocele. By means of bilateral testicular biopsy, we have investigated the spermatogenesis failure in several biological men groups and determined whether it can change the patient's candidacy for assisted reproductive technology procedures (ART).

Materials And Methods: From 1993 until 2003 in the urology and andrology department of St.

[The results of the diversion of urine into a large-intestine reservoir].

Cystectomy for bladder cancer with derivation of the urine into the colon was performed in 35 patients (30 males and 5 females). Postoperative lethality was 11.4% (4 patients).

[Ways toward improvement of the results of cystectomy in bladder cancer].

Cystectomy with derivation of urine into large bowel reservoir was performed in 35 cases of bladder cancer including five females. Four patients (11.4%) died postoperatively.

[A method for forming a large-intestine reservoir for the urine].

Eighteen patients with cancer of the urinary bladder underwent cystectomy with formation of a large intestinal reservoir for urine. The terminal large intestinal portion, 15-20 cm, the cecum, the ascending colon, and the hepatic angle of the colon were excluded to produce a reservoir from the intestinal tube. Appendectomy was performed.
