[Correction of distal hypospadias by urethral meatal advancement neo-urethroplasty-glandoplasty].

Distal hypospadias are the most frequently observed, and represent about 70% of all forms of this condition. In recent years, due to the introduction of simpler procedures which produces better results, the surgical correction of this small defect has been universally accepted. It offers a normal penile appearance and prevents associated psycological effects. In this work we evaluated the surgical correction of distal hypospadias by means of meatal advancement-neouretroplasty-glanuloplasty in two hundred patients. Good cosmetic and functional results were obtained in 86,5 and 97,0% of the cases, respectively. All patients had their urinary stream directed forward. The more important complications verified were neomeatal retraction, urethrocutaneous fistula and neomeatal stenosis in 13.5, 3.0 and 0.5%, respectively. The complications observed did not represent a worsening of the initial condition, and in almost all such cases it was corrected with a complementary procedure on an ambulatory basis or in one day of stay at the hospital, as the previous surgery.

Incontinent epispadias: surgical treatment of 38 cases.

We review 38 cases of surgically corrected incontinent epispadias with a followup of 5 months to 18 years. In 20 cases the Leadbetter, in 8 the Tanagho and in 8 the Young-Dees techniques of bladder neck reconstruction were used. Of 3 patients with minimal (15 to 25 ml.) bladder capacity the Arap procedure was performed in 1, while small constriction of the bladder neck to improve the bladder capacity and compliance was done in 2. In 1 of the latter patients a 60 ml. capacity was achieved and a secondary Leadbetter operation provided an excellent result. Continence was attained after the initial operation in 18 patients, followup is too short to determine the result in 3 and 15 did not acquire urinary control. Revision of the bladder neck plasty was performed in 11 patients, which resulted in continence in 4 and partial continence in 2. Among 34 patients with an adequate followup 22 (73.3 per cent) are continent and 8 (26.4 per cent) are incontinent. The results were similar with the 3 techniques.

Ureteral necrosis in dermatomyositis.

We describe a child with dermatomyositis and calcified necrosis in the middle third of both ureters. Histopathological examination showed vasculitis associated with ureteral necrosis and calcification. These findings together with a similar previous report in the literature have prompted us to correlate dermatomyositis in childhood with ureteral necrosis and to anticipate specifically a lesion in the middle third of the ureter because of the relative lack of blood flow in that segment.

Malakoplakia of the urinary tract.

The authors report 4 cases of urinary tract malakoplakia. This rare disease of unknown etiopathogenesis can present with a benign character in the bladder, but when the upper urinary tract is affected, loss of renal function can occur. Treatment aims to control the primary infection, as well as enhance intracellular bactericidal activity, which seems to be compromised in these cases. Cytoreductive surgery may be indicated when this treatment fails.

Retroperitoneal fibrosis: an alternative therapy.

A case of retroperitoneal fibrosis satisfactorily treated with indwelling double J catheters is presented. This method, although reserved for special cases, is an adequate alternative treatment as it allows efficient long-term drainage of kidneys without aggressive surgical dissection of ureters.

Duplicated exstrophy: report of three cases.

Three cases of duplicate exstrophy are described and the theoretical mechanisms of embryogenesis discussed. In all 3 cases there was classic pelvic skeletal deformity. Urinary control was normal in 2 of the 3 patients. The surgical approach consisted of plastic repair of the abdominal wall defect in all patients and correction of urinary incontinence in 1 patient.

[Stenosis of the renal artery as a cause of acute renal insufficiency after transplantation].

Eight cases of kidney transplant recipients that developed acute renal failure are described. Arterial renal stenosis was responsabilised for the ARF. One patient was submitted to transluminar angioplasty without success and then operated. This technique was the successful treatment in another patient. Four patient were submitted to surgical correction as first therapeutic approach. Two patients received no specific treatment. From the six treated patients five had good evolution.

Prolapsed ureterocele.

Although rare, the prolapsed ureterocele constitutes a urologic emergency that can rapidly evolve to severe conditions due to congestion and necrosis, and to obstruction of the urinary tract. A simple external resection resolves the emergency, allowing a postoperative investigation of the whole urinary tract to be performed, in order to adequately prepare urinary reconstruction.

[Vesicostomy: a temporary urinary diversion in childhood].

The authors report on 21 pediatric cases of tubeless cystostomies (19 males and 2 females). 15 cases of posterior urethral valves (septic condition and very narrow urethra). 3 primitive vesico-renal refluxes (small bladder, severe impairment of renal function and extensive dilatation of the upper urinary tract). 2 prune-belly syndromes. 1 neurogenic bladder. (Impracticable intermittent catheterization). 19 of the 21 cases showed dramatic improvement (narrowing of the upper urinary tract, disappearance of infection and resumption of staturo-ponderal thrive). Only 1 child with valves had to be put on cutaneous ureterostomy. The improvement in the upper urinary tract, as seen on the IVP, is very rapid in valve cases without reflux. The improvement is visible earlier on isotopic renal scans than on IVP. 11 children suffered acute pyelonephritis during vesicostomy. There were no cases of cutaneous peristomal modification. Simultaneous closure of the derivation and surgery of the primitive disease were performed in 10 cases after a 1-3 year period of vesicostomy. Vesicostomy will succeed in those babies who have shown clinical and biological improvement after a short period of trans-urethral or suprapubic catheterization. The suprapubic endoscopis treatment of the valves becomes possible through the vesicostomy hole excluding urethral trauma.

Vesical endometriosis.

A case is presented of vesical endometriosis treated surgically in a thirty-one-year-old woman who presented with hypogastric pain and a pelvic mass. Echography showed an intravesical tumor, and cystoscopy led to a presumptive diagnosis of bladder endometriosis. The clinical features, diagnosis, and management are discussed, based on a review of the literature.
