A significant part of the morbidity in elderly men involves pelvic organs and their autonomic neural regulation. Environmental stimuli also impair the structure and function of pelvic organs. One of these factors is citral, a widely-used cosmetic fragrance constituent, which causes severe prostatic hyperplasia in rats.

Objectives: Metachronous metastasis of renal cell carcinoma to the contralateral adrenal gland is very rare. We review our experience with 5 such patients and compare it with reports in the literature.

Methods: The records of all 350 patients who underwent nephrectomy for renal cell carcinoma in our center between 1975 and 1992 were reviewed.

Purpose: Chronic prostatitis is a common histopathological finding in prostatectomized patients. A possible interrelationship between the presence of leukocyte exudate and the extent of the hyperplastic lesions has been suggested. The aim of the present study was to analyze the effect of the immunomodulator compounds, Complete Freund Adjuvant (CFA) and cyclosporin A (CsA), administered alone or together with citral on the induction and extent of rat prostatic hyperplasia.

Purpose: The role of a combined regimen of local hyperthermia and topical chemotherapy in patients with multifocal and recurrent superficial bladder tumors not curable by transurethral resection was evaluated in a neoadjuvant organ sparing clinical study.

Materials And Methods: A total of 19 patients with multifocal, superficial grades 1 to 3 bladder tumors that recurred after intravesical chemoprophylaxis or immunoprophylaxis underwent local combined administration of microwave induced hyperthermia and intravesical chemotherapy as a debulking approach. Due to extensive superficial involvement of the bladder walls complete transurethral resection of all tumors seemed technically unfeasible in all cases and radical cystectomy was considered the treatment of choice.

The gonadotropin-releasing hormone (GnRH) test was performed on 182 patients with various degrees of varicocele before and after low, inguinal, spermatic vein ligation, and on 18 controls. The levels of follicle-stimulating hormone (FSH) and luteinizing hormone, a synthetic GnRH (LH), were evaluated before and 45 minutes after intravenous injection of 100 mcg relisorm L. FSH levels increased more than 2-fold in 118 patients [64.

Objective: To compare, before and after repair of varicocele, the semen parameters (SP) in relation to the persistence of retrograde vein flow.

Material And Methods: We examined the correlation between semen characteristics and retrograde flow (RF) into the pampiniform plexus in 158 patients with varicocele, before and after low inguinal spermatic vein ligation.

Results: The results of the investigation before surgery showed that all patients had RF and also a decrease in quantitative and qualitative SP.

We report a case of type II ureteral triplication associated with ectopic ureter. The ureter, draining the upper renal segment, entered the vagina, and the other two ureters, draining the middle and lower renal segments, had joined and entered the bladder. The anatomic findings are compatible with those predicted by the Weigert-Meyer law.

Citral is a monoterpene in wide use as an aromatic supplement in the cosmetics and food industries. Previous studies in our laboratory have shown that cutaneous application of citral on adolescent rats may induce benign prostatic hyperplasia (BPH)-like and even atypical hyperplastic changes in the ventral lobes. In the present study we investigate the possible interactions between citral and serum testosterone levels on the induction of hyperplastic changes in the ventral prostate of adolescent rats.

Urethral diverticulum in the female is an acquired lesion following infection of the para-urethral glands. Its symptoms are often nonspecific and only by increased awareness of this condition can delay in diagnosis be avoided. Radiologic imaging of the urethra allows diagnosis of this lesion and determination of its location, extent and the number of lesions.

Bacillus Calmette-Guérin (BCG) bladder instillation is an accepted treatment modality in the management of superficial transitional cell carcinoma but is associated with frequent side effects. A report of intravesical BCG-induced penile edema and meatal ulceration that occurred in 2 patients is presented. During induction therapy, both patients complained of progressive penile edema.

Objectives: To assess the benefit of performing nonstented pyeloplasty in infants.

Methods: Forty-eight consecutive pyeloplasties were performed by two surgeons using different techniques, from 1987 to 1992. One used stents in all cases (23) and the other performed a nonstented anastomosis with external drainage (25 cases).

We examined semen characteristics of 128 patients prior to low-inguinal, spermatic vein ligation for varicocele and every 2 or 3 months over the course of a year. There was a higher sperm count 26 months after surgery, and after 68 months improved motility and a higher proportion of sperm with normal morphology. 10 months to 1 year after surgery there was improvement in all 3 parameters in 106 patients (82.

The impact of the improved diagnosis of renal cell carcinoma (RCC) on the course of the disease was evaluated in 188 patients who were diagnosed and treated at a single medical center. Sixty-seven patients (group A) who had undergone nephrectomy between 1979 and 1983 for RCC initially diagnosed by intravenous pyelography (IVP) were compared with 121 patients (group B) who had undergone nephrectomy between 1983 and 1989, diagnosed by ultrasound and/or computed tomography (CT) scan. Incidental asymptomatic tumors were found in 18 of 67 (26.

Sixty-nine patients who underwent nephroureterectomy for upper urinary tract transitional cell carcinoma were included in the study. The following data were collected for each patient: grade and stage of renal/ureteral tumor, tumor location, timing of tumor appearance and recurrence in the bladder, grade and stage of each of the recurrent tumors, and number of recurrences. Follow-up ranged between 2 and 15 years.

Objective: To prospectively examine the accuracy of fine needle aspiration (FNA) for the detection of prostate cancer. Ultrasound-guided core needle biopsy of the prostate was used as the standard to which the FNA results were compared.

Patients And Methods: One-hundred patients who had been referred for urological evaluation were suspected of having prostate cancer on the basis of digital rectal examination (DRE) and/or transrectal ultrasound (TRUS).

Objective: To report tumour recurrence related to cessation of long-term therapy with thiotepa.

Patients And Methods: A group of 12 patients with low grade (I-II), low stage (TA-T1) transitional cell carcinoma of the bladder were included in the study. All patients had been treated with intravesical thiotepa for a period ranging from 24 to 71 months and none had had a recurrence for a period of between 15 and 51 months.

The vasoactive effect of a fragrance compound, citral, on rat ventral prostate is presented. A combined method of Indian-ink perfusion and postfixation transparency was used. One single dose of citral applied on the back skin of the rat induced an immediate triple response-like effect on the prostatic vascular bed.

The induction of prostatic lesions in the rat by hormonal manipulation and/or chemical carcinogens in different strains is well documented in literature. However, the selection of a strain for such studies was merely based on the laboratory husbandry facilities rather than on the animal genotype. It is well accepted that the morphology and function of the prostate exhibit a marked species-specific differences that makes extrapolation to other animals and man difficult.

Objective: To investigate whether there is an inter-relationship between chronic abacterial prostatitis and potential infertility.

Design: As part of the eligibility studies for hyperthermia treatment for chronic abacterial prostatitis patients, a large number of chronic prostatitis patients were referred to us from peripheral outpatient clinics. Sperm analysis was a routine portion of the eligibility studies.

Two hundred patients underwent nephrectomy for renal cell carcinoma (RCC) at our service in 1978-89. During follow-up four patients developed RCC in the remaining kidney and underwent a parenchymal preserving procedure as curative treatment (one enucleation, and three partial nephrectomies). The interval between the nephrectomy and the diagnosis of asynchronous RCC was 50-84 months (mean 65 months).
