Modified meatal advancement and glanuloplasty repair of distal hypospadias.

Meatal advancement with glanuloplasty is indicated in cases of distal hypospadias. The principles of this operation are safe. Incorporation of urethroplasty with meatal advancement and glanuloplasty enables treatment of the more severe cases of distal hypospadias. We have used this modified operative technique in 10 boys with only 1 complication, which probably was related to the wrong choice of urinary diversion.

Ureterocele of the lower pole ureter and an ectopic upper pole ureter in a duplex system.

We report an unusual case of a ureterocele in a duplex system, which was associated with an ectopic (vulval) upper moiety ureter. This is the second case reported in the literature of a ureterocele arising from the lower pole ureter. Surgical treatment consisted of removal of the upper segment of the kidney and its ureter. The ureterocele was excised and the lower pole ureter was reimplanted in the bladder. At followup 14 years postoperatively the patient was cured and free of urinary infection.

Nonrefluxing colonic conduit: efficiency and complications of ureterocolic anastomosis.

The efficiency of and complications in 65 cases of colonic conduit have been studied (64 cases of bladder exstrophy and 1 case of cloacal exstrophy). For the ureterocolic reimplantation, we employed the Leadbetter technique and a modified kelalis technique. The results after 1-12 years in 128 renoureteral units showed 28 complications (21 obstruction and 7 refluxing units). Other types of complications have been observed and reported in this work. The high incidence of obstruction was probably due to the long submucous tunnel in the ureterocolic reimplantation. We believe that the sigmoidal conduit is an adequate method for temporary or permanent diversion.

Treatment and prevention of complications after extravesical antireflux technique.

An extravesical antireflux technique was performed in 300 consecutive patients who presented primary vesicoureteral reflux (VUR). The following results are reported: Elimination of VUR in 99% of the cases without complications. Early complications reported include: urinary retention, suppurative pyelonephritis and fistulae. Urinary retention occurred in 2 patients presenting other congenital abnormalities. Vesicocutaneous fistulae occurred in 2 patients due to obstruction of the catheter for vesical drainage; they closed spontaneously under adequate drainage of the bladder. Suppurative pyelonephritis and/or anuria occurred in 6 patients due to transitory obstruction due to edema of the new vesicoureteral junction and were treated with bilateral nephrostomy and progressed with good results after withdrawal of the nephrostomies. Late complications included: persistence of VUR in 8 patients due to two types of technical failure, too short a tunnel and dehiscence of the muscular suture; obstruction of the new vesicoureteral junction in five ureters due to three causes, excessive dissection of the ureters, mucosal stenosis and stenosis of the new hiatus; contralateral reflux in 6 patients due to nonsystematical performance of endoscopic examination of the ureteral meatus preoperatively in the first series of 100 consecutive cases. On the basis of the results achieved, the authors give specific suggestions that allow the technical prevention of the small number of complications that may occur using the extravesical antireflux technique in the treatment of VUR.

Renovascular hypertension in children.

Due to better methods of diagnosis, an increasing number of children with renovascular hypertension are being discovered. The disease itself has variable clinical manifestations, and an adequate laboratorial workup, including arteriography and renin assays, is mandatory in suspected cases. Treatment depends on the prognostic values of the renin assays and surgery cures 80% of the patients, either by nephrectomy or by revascularization techniques. Among these, renal autotransplantation gives better exposure of the operative field, and therefore better results. In most cases, systemic infection seems to be the main cause of the inflammatory reaction within the arterial wall that causes obstruction.

Carcinoma in diverticulum of female urethra.

A case of female urethral diverticulum is reported by the authors. It is a rare disease and about 31 cases have previously been described. An analysis is made in relation to the diverticulum of the urethra and to female urethral carcinoma. Emphasis is given on the semiology and the recently acquired diagnostic procedures, as these have led to an increased number of recognized cases. In the case presented, an extended resection and a definitive urinary derivation was performed, together with chemo- and radiotherapy. A follow-up of 2.5 years showed no signs of recurrence or metastases.
