PURPOSE We assessed whether subclinical varicocele ligation improves fertility and/or semen parameters. MATERIALS AND METHODS A total of 85 patients with a subclinical varicocele diagnosed by scrotal thermography presented with infertility. Patients were randomly assigned to groups 1 (high ligation of the internal spermatic vein) and 2 (followed without(More)
OBJECTIVE To determine whether mast cell blocker (tranilast) improves fertility and/or semen parameters in severe oligozoospermia. DESIGN Placebo-controlled single-blind clinical study. SETTING Nagoya University Hospital Andrology Clinic, Nagoya, Japan. PATIENTS Fifty men with sperm density < 5 x 10(6) sperm/mL, normal serum gonadotropins, and T, and(More)
OBJECTIVE To determine whether alpha-blocker (bunazosin) improves fertility and/or semen parameters DESIGN Placebo-controlled, double-blind clinical study. SETTING Nagoya University Hospital Andrology Clinic, Nagoya, Japan. PATIENTS Thirty-four men with sperm density between 5 and 20 x 10(6) sperm/mL, normal serum gonadotropins and T, and a fertile(More)
Since a close relationship has been suggested to exist between testicular disfunction and the increased mast cells in the testis, we used a mast cell blocker for the treatment of patients with idiopathic infestility. An infertile male with idiopathic azoospermia was treated with administration of a mast cell blocker, tranilast for one year. The patient was(More)
Although varicocelectomy is generally believed to improve semen quality and the hamster egg penetration assay, these parameters do not correlate well with in vitro fertilization (IVF) success. The effect of varicocelectomy on IVF of human oocytes was examined on thirteen couples with normal female fertility, but severe oligozoospermia and the presence(More)
The treatment of patients with chronic unilateral or bilateral orchialgia, defined as intermittent or constant testicular pain of greater than 3 months and of unclear cause, is difficult. This pain significantly interferes with the daily activities of the patient. We have seen 12 patients with chronic orchialgia of unknown etiology and each had a normal(More)
We evaluated the sperm recovery rate in non-obstructive azoospermia (NOA) patients presenting with bilateral testicular atrophy characterized by testes volume of less than 10ml and FSH levels exceeding 20 mIU/ml (group NOA-1), and compared the results to those NOA cases displaying unilateral testis volume exceeding 10 ml or FSH levels less than 20 mIU/ml(More)
Direct transrectal infiltration of the prostate with antibiotics was performed in 25 selected patients with refractory chronic prostatitis, and sequential samples of urine and prostatic secretion were studied at 3-monthly intervals thereafter. The criterion for cure of chronic bacterial prostatitis was persistently sterile cultures of urine and prostatic(More)
The long-term results of endoureterotomy using a holmium laser in cases of benign ureteral stricture, uretero-pelvic junction obstruction (UPJ-O) and ureteroenteric stricture were evaluated. Twenty procedures were carried out in 18 patients. Strictures were incised with a holmium laser using a fiber passed through the ureteroscope. Sixteen of the 20(More)
BACKGROUND We reviewed the results of endoscopic ureteral incision for benign ureteral stricture, ureteropelvic junction obstruction and ureteroenteroanastomotic stricture using the holmium laser. METHODS We carried out endoscopic ureteral incision using the holmium laser through an 8-Fr semirigid or 6.9-Fr flexible ureteroscope on 17 ureters in 15(More)
