Abstract
Introduction

We describe the technique and present the preliminary results of the laparoscopic radical cystectomy technique with the extracorporeal creation of a “Y” shaped ileal orthotopic neobladder using non-absorbable mechanical suture (Fontana).

Materials and method

We describe the technique step by step and present a series of 15 patients who underwent this surgery between November 2005 and August 2009, with special emphasis on the duration of the surgery, urinary diversion time, intraoperative and postoperative complications, daytime and night time continence and the frequency of postoperative micturition.

Results

The mean follow-up of the series was 24 months (6–32). The mean duration of surgery was 280 (range 210–345)min and the mean urinary diversion time was 54.5 (range 40–75)min. There were no intraoperative complications and the average hospitalization time was 7 (range 5–15) days. During the follow-up, there were 5 late postoperative complications, 2 cases of urinary infection with good response to antibiotic treatment and 3 uretero-neovesical anastomosis strictures, which were treated with percutaneous balloon dilation, with a good functional result. No lithiasis was found in the neobladder. Complete daytime continence was obtained in 13/14 patients (92.9%) and complete nighttime continence in 6/14 (42.9%). One patient (6.7%) required clean intermittent self-catheterization as the patient did not micturate spontaneously.

Conclusions

The creation of a “Y” shaped ileal orthotopic neobladder using non-absorbable mechanical suture is a feasible, fast and safe technique and it provides promising functional results. Further follow-up is required to determine its long-term results.

Resumen
Introducción

se describe la técnica y se presentan los resultados preliminares de la técnica de cistectomía radical laparoscópica con confección extracorpórea de neovejiga ortotópica ileal en forma de “Y”, usando una sutura mecánica no reabsorbible (Fontana).

Material y método

se describe paso a paso la técnica y se presenta una serie de 15 pacientes sometidos a esta cirugía entre noviembre de 2005 y agosto de 2009, con especial énfasis en el tiempo de cirugía, tiempo de derivación urinaria, las complicaciones intraoperatorias y postoperatorias, la continencia diurna y nocturna y la frecuencia miccional postoperatoria.

Resultados

la mediana de seguimiento de la serie es de 24 meses (6-32). El tiempo quirúrgico medio fue 280 (rango: 210-345) minutos y el tiempo medio de la derivación urinaria fue 54,5 (rango: 40-75) minutos. No se presentaron complicaciones intraoperatorias y el tiempo promedio de hospitalización fue de 7 días (rango: 5-15). Durante el seguimiento se presentaron 5 complicaciones postoperatorias tardías, dos cuadros de infección urinaria con buena respuesta al tratamiento antibiótico y tres estenosis de la anastomosis uretero-neovesical, que se han manejado con una dilatación percutánea con balón con un buen resultado funcional. No se han encontrado litiasis en la neovejiga. Se obtuvo continencia diurna completa en 13 de 14 pacientes (92,9%) y nocturna completa en 6 de 14 (42,9%). Un paciente (6,7%) precisa autosondaje limpio intermitente por no presentar micción espontánea.

Conclusiones

la neovejiga ortotópica ileal en forma de “Y” usando una sutura mecánica no reabsorbible es una técnica factible, rápida, segura y que permite resultados funcionales prometedores. Se necesita mayor seguimiento para determinar sus resultados a largo plazo.
