[Orthotopic substitutive cystoplasty in women. Technical modifications in anterior exenteration: results in 9 cases]. / Plastia de sustitución vesical ortotópica en la mujer. Modificaciones técnicas en la exenteración anterior: resultado en 9 casos.

OBJECTIVE: The results obtained in 9 female patients who underwent bladder substitution after a modified anterior pelvic exenteration are presented. METHODS: From 1994 to 1999, 9 women underwent bladder substitution after a modified anterior pelvic exenteration that preserved the two distal thirds of the urethra, the pubourethral ligaments and endo-pelvic fascia and limited laterovaginal dissection to preserve the innervation of the striated sphincter for continence. RESULTS: The bladder capacity was 332.9 +/- 35.6 ml and urinary flow was 17.7 +/- 2.9 ml/sec. Seven patients are completely continent and two patients have stress incontinence grade II. None of the patients had difficulty with bladder emptying. Fistula (one case) and diarrhea (one case) were the most important complications. CONCLUSIONS: Our approach is based on a better understanding of the anatomical mechanisms of female continence and the viability of the remaining urethra from the oncologic perspective. This technique achieves a high level of patient satisfaction and quality of life.

[Primary abscess of the psoas. Report of a case]. / Absceso primario de psoas. A propósito de un caso.

Psoas abscess is an uncommon condition at the present time. The initial anodyne signs and symptoms make diagnosis difficult. It can be diagnosed and rated as primary when the origin is not found, or secondary when a focus for infection spreading is detected. Drainage either percutaneously or by open surgery, and antibiotic therapy are the choice treatment, achieving an important survival rate. This paper presents a new case of psoas abscess, including a revision of the diagnosis and treatment of this condition.

[Renal agenesis, cranial blind ureter and ureterocele. Report of a case]. / Agenesia renal, uréter ciego craneal y ureterocele. A propósito de un caso.

OBJECTIVES: We report a case of associated malformations in a young male with recurrent epididymitis. METHODS: In our study we used the following techniques: ultrasound, intravenous urography, retrograde pyelography, computed tomography and cystoscopy. RESULTS: We observed three coexisting congenital malformations: renal agenesis, cranial blind-ending ureter and ureterocele. CONCLUSIONS: Different urologic malformations are usually found in association. In our view only symptomatic ureteroceles require treatment.

[Ileal ureteroplasties]. / Ureteroplastias ileales.

When the ureter is extensively compromised, preservation of the kidney without recurring to external diversion may be attempted by a psoas bladder procedure, transureteroureterostomy, renal autotransplantation or ureteral substitution using the intestine. The first two are not always possible and transplantation is perhaps extremely disproportionate. We therefore recur to ureteral substitution using the intestine. Ureteral substitution may be partial or total, although it is recommended to preserve the upper segment of the lumbar ureter whenever possible. The procedure can be performed using the entire ileal segment with or without modelling to the appropriate thickness. Reducing the diameter of the ileal graft will enhance urine propulsion, reduce mucus secretion and improve antireflux dynamics. Nine cases of ureteral substitution are described herein. Treatment depended on the underlying pathology, extent of ureteral compromise and location. The techniques employed were ureteral substitution with or without modelling and ureteral substitution combined with a bladder repair procedure.

[Verrucous carcinoma of the penis. Presentation of 3 new cases]. / Carcinoma verrucoso de pene. Aportación de tres nuevos casos.

Penis carcinoma shows an incidence between 0.3-1% of all male neoplasias. The verruciform variety represents 5-10% of total penis carcinoma. Verruciform carcinoma is a variety of squamous carcinoma presenting a usually benign behaviour and related to some virus species (H.P.V.). Three cases are presented with ages ranging between 47-87 years-old, all of which undergoing partial penectomy, their progression being monitored for two years.

[Keratinizing desquamative squamous metaplasia. Massive involvement of vesical mucosa]. / Metaplasia escamosa descamativa queratinizante. Afectación masiva de mucosa vesical.

We report on a case of squamous metaplasia involving the entire bladder mucosa. Diagnosis was established from multiple biopsies and urinary cytology. We discuss the term used to define lesions whose potential to become malignant is the subject of controversy, and the currently available treatment modalities used to achieve cure.
