Urothelial tumors of the bladder.

Neoplasms originating from the transitional epithelium of the urinary bladder are rare in children. This paper examines the clinical, epidemiological and histopathological characteristics of 3 such cases. The patients were males aged 4, 8 and 14 years at the time of diagnosis.

Paediatric urolithiasis in Greece.

A group of 44 patients, aged from 10 months to 14 years, underwent surgery for urinary calculi over a 7-year period (1982-1989). Eleven patients had bilateral or multiple calculi (total number of stones = 55, 20 of which were staghorn). Metabolic disorders (n = 25) and Proteus urinary infection (n = 15) were the 2 factors most often associated with lithiasis.

Ostioplasty: a simple technique for ureterovesical reconstruction following intravesical ureterocelectomy.

A simple operation for the management of simple, i.e. intravesical, ureteroceles, which we have named 'ostioplasty', is presented.

Evaluation of open surgery for staghorn calculi in children.

We evaluated the results of open surgery in 19 children with staghorn calculi. The median age was 3.5 years (range 10 months to 14 years).

Surgical treatment of ectopic ureteroceles and the role of heminephrectomy with subtotal ureterectomy.

We evaluated 16 patients, 2 weeks to 8 years of age (median: 18 months), operated on for ectopic ureterocele. Five patients, in whom the upper kidney, drained by the ureter with the ureterocele, was viable, were submitted to excision of the ureterocele with reimplantation of the double ureter (n = 4) or high ureteroureterostomy (n = 1). A 2-week-old baby with a non-functioning kidney was treated by nephroureterectomy.
