[Prepuce simulating an igloo].

OBJECTIVE: To report what could be the first reference of a prepucial congenital abnormality which has been termed an "igloo-like prepuce". The presence of a prepuce completely covering the glans and presenting the outer opening on the ventral side, resembles the ice constructions used as temporary dwelling by certain groups of eskimos. METHODS: Two cases with this unusual abnormality seen in two young brothers are described. RESULTS AND CONCLUSIONS: The "igloo-like prepuce" is a prepucial congenial abnormality with rare incidence which carries no other genitourinary condition but which translates in a merely aesthetic alteration.

[Congenital prepubic sinus].

Presentation of one case of Urethral Duplicity of the Blind Epispadias variant, also known as Congenital Prepubic Sinus. This form of accessory urethra is a congenital malformation which consists in a pseudofistular passage which starts at the proximity of the bladder's anterior side-though uncommunicated with it-and spreads to the skin of the pubic area where it ends. No other malformative condition was found in the comprehensive study conducted, and only the existence of repeat episodes of mucopurulent drainage material advised its removal. This manoeuvre was followed by a complete cure and, after more than two years follow-up, the patient remains asymptomatic.

[Urinary retention caused by hematocolpos secondary to imperforate hymen].

We report on two adolescent girls with imperforate hymen that had presented clinically as urinary retention. In the second case described herein, hydrocolpos could have resulted from the imperforate hymen and might have caused the congenital hydronephrosis incorrectly diagnosed during the neonatal period and childhood as such.

[Endoscopic ureterectomy].

Endoscopic ureterectomy is a minimally invasive surgical technique indicated in cases warranting ureterectomy to complement extended nephrectomy for pyelocaliceal urothelial carcinoma. The results achieved are identical to those of conventional ureterectomy (open surgery) without the inconvenience or sequelae that usually present with the latter procedure. In 1982, the authors developed the modified Dell'Adami and Breda endoscopic ureterectomy technique. To date, they have performed their modified technique in 10 cases: 9 with infiltrating urothelial or highly malignant pyelic or caliceal tumor and 1 with diffuse leukoplasia and cholesteatoma of renal pelvis. The technique described herein permits intussusception of the ureter into the bladder by transurethral traction of a Chevassu ureteral catheter to which that cephalad end of the ureter is attached during the extended nephrectomy procedure. Once intussusception of the ureter has been achieved, a resectoscope is used to cut the ureter at the level of the ureteral meatus. Thereafter the mucosa of the corresponding trigonal horn is completely resected. The results are highly satisfactory in patients whose ureter has not previously been submitted to open surgery and is not compromised by tumor spread.

[Percutaneous endoscopic urethrocervicopexy].

A minimally invasive surgical technique that remarkably simplifies the Stamey procedure is described herein. The technique shortens the operating time and achieves a success rate of over 80%. Thus, we believe this technique should be considered in the treatment of stress urinary incontinence in females.

[Wilms' tumor associated with membranous glomerulonephritis].

We report on a case of Wilms tumor associated with segmental, focal membranous glomerulonephritis in the contralateral kidney of a 4-year-old boy. The possible etiopathogenesis and outcome of this rare disease entity are discussed. Except for rare cases, this condition usually progresses to end-stage renal failure.

[Epidermoid cyst of the testis in children].

An epidermoid cyst of the testis was found in a 10 year-old child. The interest of this case report resides in the fact that it is rare in childhood and that its pathogenesis is not well known. Although the treatment of this condition remains controversial, a high orchidectomy through the inguinal tract was performed to a correct pathological diagnosis.

[Pneumatic dilatation of urethral stenosis].

We report on a series of 32 patients with urethral strictures of different etiology, site, and morphology that were submitted to treatment by balloon dilatation. The results achieved corroborate the usefulness of this procedure. It is easy to perform and there are no complications. Furthermore, it affords economic advantages since it can be performed with simple local anesthesia on an outpatient basis. For all the foregoing reasons, we believe that balloon dilatation is a useful procedure in the treatment of urethral strictures that permits raising the success rate in well-selected cases of urethral strictures untreated previously by other surgical procedures. Balloon dilatation and endoscopic internal urethrotomy are the procedures of choice in the treatment of a vast majority of strictures.
