Metanephric adenoma: case report and review of the literature.

Metanephric adenomas are benign tumors frequently found post-mortem (from 7% to 22% of autopsies) which originate from distal tubules; they are generally small in dimensions (smaller than 1 cm) and located in the renal cortex. Etiology is unknown, even though they could be associated with smoke, tubular nephrosclerosis, dialysis. An endocrinal relationship was proposed, because of its more frequent incidence in female (2:1).

Our experience in the treatment of penile curvature.

Objectives: Evaluation of the authors' results achieved using corporoplasty in patients treated for penile curvature from 1/1/1993 to 31/12/2002.

Materials And Methods: 26 patients underwent corporoplasty to correct penile curvature: congenital curvature without hypospadias or epispadias in 22 patients (aged 17 to 42) and curvature due to La Peyronie's disease in 4 patients (aged 48 to 65). In the latter 4 cases corporoplasty was chosen, instead of plaque excision or incision, since the plaque was quite small-sized and well stabilized, causing an overall limited curvature in a proportionately long penis with perfectly preserved erectile functions.

[Orthotopic ileal neobladder: technical procedures and long-term follow-up].

From January 1992 to September 1997, 29 male patients between the age of 39 and 71 affected by localized bladder cancer underwent radical cystectomy and received detubularized orthotopic ileal neobladder. In most cases we performed the ileal neobladder utilizing the Studer technique, preferring the Wallace 1 method for the uretero-ileal anastomosis, that seems to reduce the risk of stenosis. In some patients we experimented different techniques.

[Papillary cystadenoma of the epididymis. 2 case reports].

Tumors of the epididymis are very rare. They are benign tumors in 75 per cent of the cases. Papillary cystadenoma represents 4-9 per cent of epididymal benign tumors.

[Renal oncocytoma in the single kidney after previous surgery of renal carcinoma. Apropos of 2 cases].

Renal oncocytoma is a neoplasm which rarely occurs in patients with solitary kidney, the other being absent because of a previous nephrectomy performed for renal cancer. We present two case reports and a literature review. We have studied some important problems such as the histogenesis, the potential for malignancy, the diagnosis, the treatment and the follow up.

Ureteroscopy and stone lithotripsy with lithoclast: personal experience.

Ureteroscopy has become a common technique in the diagnosis and treatment of ureteral pathologies, but this procedure is quite invasive and some complications have been reported in literature. In our Institute 49 patients underwent ureteroscopy and ballistic lithotripsy with lithoclast for ureteral stones. The stones were localized both in the middle and distal part of the ureter.
