A case of an ectopic vas deferens of an undescended testis is presented which was associated with hypospadias. These abnormalities came to light because of the systematic approach we have adopted for the investigation of hypospadias in our hospital.
Recurrent bleeding, the high occurrence of encephalopathy, and the impairment of hepatic function in the successful cases of portasystemic shunts have led to increasing dissatisfaction with these procedures in recent years. Between March 1974 and November 1990 we have operated on 15 children for bleeding esophageal varices using the Sugiura procedure (esophageal transection with paraesophagogastric devascularization). In two cases the entire procedure was performed via the thoracic approach. The spleen was left in place in five cases. We have had no mortality. Operative complications included bleeding in the early postoperative period in two children and partial leakage from the esophageal suture in two others. Follow-up was from 4 years 3 months to 16 years 8 months with an average of 10 years 4 months. Long-term results have been gratifying in 12 patients (80%) with disappearance of the varices and no evidence of recurrent bleeding. Three children (20% of the patients) had recurrent bleeding 4 1/2 years, 4 years 2 months, and 2 1/2 years after the surgical procedure. In all cases there was no evidence of esophageal stenosis, gastroesophageal reflux, or hiatal hernia, nor signs of encephalopathy nor impairment of hepatic function. In our opinion the Sugiura procedure is a valid procedure in the surgical treatment of esophageal varices bleeding in the pediatric age with a high rate of success (80%) and without late complications.
From June 1982 to November 1990, 37 patients, aged 13 to 19 years (35 males and 2 females), were treated in our division for neuropathic urinary incontinence with an artificial sphincter. All patients were treated before sphincter implantation with drugs, transurethral sphincterotomy in boys, and bladder flap urethroplasty was carried out in females during the surgical procedure. The cuff was placed at the bladder neck in 33 cases, and in 4 cases at the urethral bulb. The sphincter was activated about 3 weeks after implantation and after 2 months in two patients with associated bladder augmentation. Operative and perioperative complications occurred in four cases during the initial phase of our experience. Later we had to perform 19 revisions on 14 patients due to mechanical and surgical failure (reoperation rate, 0.38). Thirty-three patients are presently dry (90% of successes). Postoperatively, normal upper urinary tract conditions were found in all patients except two.
The authors discuss the anatomical, clinical, and US patterns of 5 cases of urachal cysts observed in pediatric patients (average age: 9.2 months) over the last 4 years. All cases had surgical confirmation. Linear and convex probes with 3.75, 5, and 7.5 MHz frequency were employed. Most of the observed lesions were oval in shape, their size ranging 3-6 cm; they were found in ventral-epivesical regions and had no mobility. Liquid echotexture with hyperechoic deposits on the lower layers was observed in 2 cases, and inhomogeneous solid or complex mass-like echotexture in 3 cases (suppurated cysts). Differential diagnosis includes mesenteric cyst, simple and teratomatous ovarian cyst, bladder diverticulum and hydrometrocolpos. Echotomography exhibited high accuracy in detecting this kind of lesion and allowed guidance of percutaneous drainage for the preoperative treatment of infected cysts. Both cystography and CT appeared to be useless.
The treatment of urologic complications from myelomeningocele and especially of vesico-renal reflux is a controversial problem. A series of 26 reimplanted ureters in 17 children, with good results in more than 85%, is reported. Ureteroneocystostomy, carried out with a few technical innovation, may represent a useful method for the treatment of vesico-renal reflux and obstruction of the uretero-vesical junction in neurogenic bladder associated with myelomeningocele. This surgical approach leads to the disappearance of the reflux, decrease of dilatation of the upper urinary tract and preservation of renal function in most cases; moreover, infection can be more easily controlled. Ureteral reimplantation should be preceded by periodic urethral dilatation, external transurethral sphincterotomy, and pharmacologic regulation in order to attempt to decrease urethral resistance. After successful surgery, it is possible to try to reeducate the bladder. Reimplantation should be preferred to permanent urinary diversion even if there is gross reflux.
