[Preparation of the scrotal skin for urethroplasty: depilation technique].

OBJECTIVE: To describe a simple method of depilation of scrotal skin and the advantages of utilizing scrotal skin flaps for urethroplasty in the postpubertal male. METHODS: Depilation of the scrotal flap is achieved by electrocoagulating the dermal papillae with a needle specifically designed for scrotal hair. The frequency and the number of depilations are determined by the hair biological cycle. RESULTS: Scrotal hair is removed with no injury to tissue or changes in the characteristics of scrotal skin. This method of depilation is well-tolerated and no complication has been observed. CONCLUSION: The scrotal skin depilated provides excellent flaps for reconstructive surgery of complex urethral strictures, specially those extending beyond the penoscrotal angle up to the membranous and prostatic inframontanum portion.

[Autoplastic closure of vesicovaginal fistulae with posterosuperior bladder flap (Gil-Vernet operation)].

OBJECTIVE: To describe our experience in the treatment of vesico-vaginal fistula with autoplastic closure using a postero-superior vesical flap. Also, to discuss the technical details of the procedure. MATERIAL AND METHOD: Between 1985 and 1996, 15 patients with vesico-vaginal fistulae secondary to gynaecological surgery were operated. The fistula was considered complex in 5 patients based on previous attempts for surgical closure, number of openings or because they were located in the posterior gradient of the vesical neck. In all cases, autoplastic closure of the fistula was done with a vesical flap through an extraperitoneal abdominal approach. RESULTS: In 100% cases closure of the fistula was achieved at the first surgical attempt. There was no need to interpose vascular tissue between the bladder and the vagina to secure closure of fistula. Post-operatively, 5 patients showed decreased vesical capacity which was recovered within six months; two patients had non-obstructive post-surgical vesical instability. No patient had changes in the mechanism of urinary continence.

[Early diagnosis by opportunistic screening in cancer of the prostate. Results of a 1-year protocol. Comparison with historical data].

RATIONALE: The high prevalence of Prostate Cancer (PC) and long survival of patients with advanced disease, added to the high cost of palliative treatment (hormone therapy), versus the existence of curative therapies at earlier stages, fully justify the campaigns for early diagnosis. The objective of the study was to increase the number of cases diagnosed at local stages, using an opportunistic screening methodology. METHODS: All male patients between 50-70 years of age, seen over one year in Urology and primary care in CAP-Barceloneta because of urinary symptomatology, were included in a screening program. This cohort were performed total PSA determination and digital rectal examination. When digital rectal examination was suspicious and/or PSA values higher than 4 ng/ml, they underwent echo-guided prostate biopsy. RESULTS: A total of 595 male were seen; 43.9% met the inclusion criteria; 39.4% were rated as suspicious, neoplasia being confirmed in 51% of these. Prevalence of PC in this cohort was 20.1%, half of them in local stage. CONCLUSIONS: Populational screening in PC has proven to be ineffective from a health care standpoint, as opposed to opportunistic screening. Overdiagnosis was not significant, although there were more cases diagnosed in organ-confined stages, this is, eligible for curative therapy; thus, hormone therapy and the resulting morbidity were significantly decreased; quality of life of patients under curative treatment was improved; there was a large reduction of health care costs and, although it will have to be further confirmed in large multicentre series, we believe survival was improved.

[Epidemiologic data of uro-oncologic pathology in a urology service of a university general hospital. Comments regarding cancer of the prostate].

Data from 92, 93 and 94 tumoral records is analyzed based on the first visit system, staging at time of diagnosis, intervals between visits and management. After finding data unsatisfactory, a program for health care improvement is developed in order to secure diagnosis at earlier stages which may allow for curative radical treatment. The program was implemented in 1995. Results are communicated, and compared with those from previous years; the effectiveness of the program is verified.

[Urocolpos: a cause of pseudo-incontinence in aged women].

Presentation of our experience in three cases of urocolpos (acquired pudendal lip fusion), a series numerically equivalent to the total number of cases published until now. All patients in our series were older women and presented complete fusion of the small pudendal lips, with only a small pointed puncture in the lower part of the vulva. The main clinical signs and symptoms in our series were: urinary infection in 100%, false incontinence in 66% due to output of urine retained in the vagina, a symptom that has not been described earlier, and acute urine retention in 33%. All patients were successfully treated by means of surgical loosening of the fusioned lips and application of topical estrogens. An analysis is made of clinical and pathoanatomical features which differentiate this entity from the sclerotic and atrophic lichen. Finally, an etiopathogenic hypothesis is raised to explain the fusion acquired by the small pudendal lips in the urocolpos.

[Adrenal hemangioma: review of the literature].

Hemangiomas are rarely encountered in the adrenal gland. Only 48 surgical cases of adrenal hemangioma have been reported, with four additional cases not surgically treated. Literature has been reviewed, including Japanese, which had not been done up to now. One additional case removed surgically is presented herein. The only 4 cases of hemangiosarcoma reported in the literature are included, although no relation has been described between benign and malignant vascular tumors. Comment includes definition, classification, clinical aspects, diagnostic procedures, complications and treatment.

[Results of a prospective study of chemoprophylaxis with alternating mitomycin-C and BCG: complete response and recurrence and progression index].

OBJECTIVES: The high incidence of recurrence in superficial urothelial cancer warrants the use of chemoprophylaxis; however, the results achieved to date have been unsatisfactory. The present study investigated the possibility of reducing the incidence of recurrence of superficial urothelial cancer post-TUR and disease progression. METHODS/RESULTS: 99 patients were treated with monthly instillations of mitomycin-C and BCG alternately for one year, which commenced three weeks following TUR. The incidence of recurrence and progression were 15.3% and 5.10%, respectively. Treatment was well-tolerated and there were minimum side effects. CONCLUSIONS: Chemoprophylaxis with alternating mitomycin-C and BCG therapy in patients with superficial urothelial cancer achieves good results. It is well-tolerated and few side effects were observed.

[Perineal neurilemmoma].

OBJECTIVES: Neurilemoma or Schwannoma is a rare benign tumor which may affect any nerve of the body. Genitourinary involvement is rare. Herein we describe a case of neurilemoma of the perineum. To our knowledge, only one case involving this site has been previously described in the literature. METHODS/RESULTS: We report on a patient with an asymptomatic, solitary perineal tumor. The presumptive diagnosis of a benign tumor was made on the basis of the ultrasound and CT findings. Pathological analysis disclosed the typical Verocay bodies of a neurilemoma. CONCLUSIONS: The treatment of choice is by simple surgical excision. Tumor recurrence is rare.

[Feminization: a paradoxical effect of stimulation with hCG/hMG in the infertile male].

Male feminization is an uncommon and complex phenomenon which occurs as a consequence of an imbalance in the effective oestrogen/androgen relationship. One of the many approaches used in the treatment of idiopathic male infertility is hCG/hMG stimulation. This paper reports one case of an infertile male treated with hCG/hMG after surgical correction of a varicocele, which resulted in a feminization effect evidenced by gynaecomastia and severe spermatogenesis blockade. When therapy was discontinued the feminization disappeared, a rebound phenomenon with normalization of most of the seminal parameters being seen. No other fully documented cases were found in the literature. Finally, the pathoetiological mechanisms involved in the feminization are analyzed and a revision is made of the causes that may cause it.

[Changes in deposition pattern as presentation form of uretero-intestinal endometriosis].

A case of ureteric and colonic obstruction secondary to endometriosis is described. We briefly review its pathogenesis and discuss the urologic and bowel implications, symptoms and signs, diagnosis and treatment. Because it is usually silent, urographic evaluation is advisable in all cases of endometriosis. Treatment is by surgery and adjuvant hormone therapy is given preoperatively or postoperatively for residual disease.

[A prospective and randomized study of the complete response, index of recurrences and progression in superficial bladder carcinoma treated with mitomycin C alone versus mitomycin C and BCG alternatively].

The results of a comparative randomized study on intravesical chemoprophylaxis are presented. The study comprised 66 patients; one group of 29 patients received mitomycin C alone, while another group of 37 patients received mitomycin C and alternating BCG therapy. This latter treatment modality was found to achieve a slightly higher complete response rate and a much lower tumor progression rate. Although these results were not statistically significant (p > 0.05), they indicate that if the study were comprised of a larger series, the combined modality may be shown to achieve better results than the other modalities currently used.

[Bladder involvement in non-Hodgkin's lymphoma. Diagnosis and therapeutic response].

Presentation of one case of non-Hodgkin lymphoma (NHL) in a 76 year-old, female patient presenting with giant abdominal mass, secondary tumoral vesical infiltration and bilateral obstructive uropathy diagnosed by UIV, CAT and cystoscopy-biopsy. Transitory deobstruction with 'pig-tail' catheter allowed administration of therapy with multiple chemotherapy with excellent response. The radiological, endoscopic and histopathological findings, as well as the incidence of the uncommon vesical pathologies are reviewed.

[Eosinophilic cystitis as a special form of response to mitomycin C. Analysis and comments on our cases].

We analyzed 29 cases of eosinophilic cystitis in a group of 80 patients with lower urothelial carcinoma who had been treated with mitomycin-C. Only 6 cases (20.7%) had presented symptoms and signs compatible with acute cystitis. The remaining patients had been diagnosed histopathologically by routine follow-up bladder biopsy. Urine cytology revealed abundant eosinophils in 58.6% of the patients with eosinophilic cystitis while urine culture was negative for all patients. No patient had a previous history of allergy or asthma. We discuss the possible etiopathogenic mechanisms of this rare nosologic entity, the relationship to the immune system and the role of the foregoing in the capacity to control urothelial carcinoma locally.

[Vesico-sigmoidal fistulas. Evaluation of the diagnostic performance of the complementary tests in our series].

We analyzed 14 cases of colovesical fistula that had been diagnosed and treated at the urology and gastroenterology and general surgery services of our hospital from 1986-1990. In 85.7% of the cases, the fistula had been caused by a tumor (adenocarcinoma of the colon) and in 14.3% by inflammatory disease (diverticulitis of the colon). All patients presented a varying degree of micturition syndrome; 30% had pneumaturia and 40% fecaluria. Cystoscopy proved to be the most effective in diagnosing colovesical fistula. It permitted visualization of the fistula or passage of fecal material to the bladder in 33% of the cases, while indirect endoscopic signs could be observed in 100%. Furthermore, it permitted the anatomopathological diagnosis of adenocarcinoma of the colon in 5 cases. We performed one-stage en bloc radical surgery in 57% of the cases, shotgun barrel discharge colostomy in 2 cases, exploration laparotomy in 3 and treatment was withheld in 1 case. The overall survival for the group submitted to radical surgery was 19.5 +/- 8.0 months. There were 4 deaths from metastasis, 2 from sepsis originating in the abdomen and the remaining deaths were due to iliofemoral venous thrombosis, cardiovascular disease and pneumopathy.

[Therapeutic and diagnostic ureterorenoscopy. Analysis of the procedure and results].

The present study reports our experience with URS. With this procedure, we have achieved results similar to those reported in the literature. Of a total of 97 URS procedures, 12 cases (17.5%) presented minor complications which resolved with conservative treatment. One patient presented ureteral perforation, a major complication that warranted open surgery. No renal unit was lost. The procedure permitted accurate diagnosis in all of the cases with a doubtful ureteric pathology. The foregoing demonstrates its high sensitivity and specificity.

[Plasmocellular balanoposthitis of Zoon].

Plasma cell balinitis of Zoon is a well-defined and easily-recognized disease entity that is little-known in urology. Our clinical experience in 5 cases is reported herein. The uncommon presentation of this condition in a 12-year-old patient is underscored. The clinical picture, gross features of the typical erythroplastic plaque, the differential diagnosis with special reference to Queyrat's erythroplasia, and the characteristic histologic features are described. Our experience confirms the inefficacy of topical treatment with antiseptic agents and corticosteroids. Circumcision is still the only effective treatment of this disease.
