AIMTo evaluate the treatment outcome of antegrade internal spermatic vein sclerotherapy in men with non-obstructive azoospermia or severe oligoteratoasthenospermia (OTA) as a result of varicocele.

METHODSBetween September 1995 and January 2004, 47 patients (mean age 33.8 +/- 6.3 years) underwent antegrade internal spermatic vein sclerotherapy for the treatment of varicocele with azoospermia (14 patients) or severe OTA (33 patients). Testicular core biopsy was also performed in complete azoospermic patients who provided informed consent. The outcome was assessed in terms of improvement in semen parameters and conception rate.

RESULTSForty-two (89.4%) of 47 patients had bilateral varicocele. Serum follicle stimulating hormone (FSH) did not differ between patients with azoospermia and severe OTA. After the follow-up of 24.8 +/- 9.2 months, significant improvement was noted in mean sperm concentration, motility and morphology in 35 patients (74.5%). Comparison between groups during the follow-up revealed significantly higher values of sperm concentration, motility and normal morphology in the severe OTA group. Pregnancy was achieved in 14 cases (29.8%). Testicular histopathology of the azoospermic patients with postoperative induction of spermatogenesis revealed maturation arrest at spermatid stage, Sertoli-cell-only (SCO) with focal spermatogenesis or hypospermatogenesis. None of the patients with pure SCO pattern or maturation arrest at spermatocyte stage achieved spermatogenesis after the treatment. Preoperative serum FSH levels didn't relate to treatment outcome.

CONCLUSIONAntegrade internal spermatic vein sclerotherapy is an easy and effective treatment for symptomatic varicocele. It can significantly reverse testicular dysfunction and improve spermatogenesis in men with severe OTA, as well as induce sperm production in men with azoospermia, improving pregnancy rates in subfertile couples.

AIMTo determine retrospectively the safety and efficacy of extracorporeal shock wave therapy (ESWT) in patients with Peyronie's disease.

METHODSFifty-three patients with stable Peyronie's disease underwent ESWT (group 1). Fifteen patients matched with the baseline characteristic of the patients in group 1, who received no treatment, were used as the control (group 2). The patients' erectile function (International Index of Erectile Function [IIEF-5] score), pain severity (visual analog scale), plaque size and degree of penile angulation were assessed before and after the treatment in group 1 and during the follow-up in group 2.

RESULTSThe mean follow-up time was 32 months (range: 6-64 months) in group 1 and 35 months (range: 9-48 months) in group 2. All the patients were available for the follow-up. Considering erectile function and plaque size, no significant changes (P > 0.05) were observed in group 1 before or after the ESWT. A total of 39 patients (74%) reported a significant effect in pain relief in group 1 after ESWT. However, regarding improvement in pain, IIEF-5 score and plaque size, no significant differences were observed between the two groups. In 21 patients (40%) of group 1, the deviation angle was decreased more than 10 degrees with a mean reduction in all patients of 11 degrees (range: 6-20 degrees). No serious complications were noted considering ESWT procedure.

CONCLUSIONESWT is a minimally invasive and safe alternative procedure for the treatment of Peyronie's disease. However, the effect of ESWT on penile pain, sexual function and plaque size remains questionable.

AIMTo identify possible risk factors for erectile dysfunction (ED) after transurethral resection of prostate (TURP) for benign prostatic hyperplasia (BPH).

METHODSBetween March 1999 and March 2004, 629 patients underwent TURP in our department for the treatment of symptomatic BPH. All patients underwent transrectal ultrasound examination. In addition, the flow rate, urine residue, International Prostate Symptom Score (IPSS) and quality of life (QOL) were recorded for those who presented without a catheter. Finally, the erectile function of the patient was evaluated according to the International Index of Erectile Function Instrument (IIEF-5) questionnaire. It was determined that ED existed where there was a total score of less than 21. The flow rate, IPSS and QOL assessment were performed at 3 and 6 months post-treatment. The IIEF-5 assessment was repeated at a 6-month follow-up. A logistic regression analysis was used to identify potential risk factors for ED.

RESULTSAt baseline, 522 (83%) patients answered the IIEF-5 questionnaire. The mean patient age was (63.7+/-9.7) years. The ED rate was 65%. After 6 months, 459 (88%) out of the 522 patients returned the IIEF questionnaire. The rest of the group was excluded from the statistical analysis. Six months after TURP, the rate of patients reporting ED increased to 77%. Statistical analysis revealed that the only important factors associated with newly reported ED after TURP were diabetes mellitus (P = 0.003, r = 3.67) and observed intraoperative capsular perforation (P = 0.02, r = 1.12).

CONCLUSIONThe incidence of postoperative, newly reported ED after TURP was 12%. Risk factors for its occurrence were diabetes mellitus and intraoperative capsular perforation.
