Abstract
Background

The ureteral disinsertion with bladder cuff technique continues to evolve. We present the endoscopic laser transurethral technique combined with a transperitoneal and retroperitoneal laparoscopic approach in lateral decubitus, without patient repositioning, for treating urothelial carcinomas of the upper urinary tract.

Materials and methods

We present 3 laparoscopic nephroureterectomies: 1 transperitoneal and 2 retroperitoneal. Disinsertion was performed in lateral decubitus using a flexible cystoscope and a 365-μm holmium laser fiber. The endoscopic technique was progressively adapted to 3-port and single-port retroperitoneoscopic approaches. Before laparoscopic handling of the kidney, ureter was clamped below the tumor. The endoscopic technique was then started. Both approaches were simultaneously employed.

Results

Nephroureterectomies were achieved performing en bloc endoscopic disinsertion of the bladder cuff and ensuring a closed system comparable to open technique. The second case required reconversion due to technical problems and extension of the surgical time. No relapses were diagnosed during follow-up.

Conclusion

Results are comparable to open surgery, technique ensured compliance to oncology principles, enabled disinsertion in lateral decubitus and avoid patient repositioning saving surgical time.

The results reflect the benefits of minimally invasive surgery in all cases.

Resumen
Introducción

La técnica de desinserción ureteral con rodete vesical continúa su evolución. Presentamos la técnica láser-endoscópica transuretral combinada con abordaje trans y retroperitoneal laparoscópicos en decúbito lateral, sin reposicionamiento del paciente para carcinomas uroteliales del tracto urinario superior.

Materiales y métodos

Presentamos 3 nefroureterectomías laparoscópicas, una trans y 2 retroperitoneales. La desinserción se realizó en decúbito lateral utilizando un cistoscopio flexible y una fibra de 365μ de laser Holmio. La técnica endoscópica se adaptó progresivamente a los abordajes retroperitoneoscópicos de 3 puertos y puerto único. Antes de la manipulación laparoscópica del riñón el uréter fue clipado por debajo del tumor, iniciándose posteriormente la técnica endoscópica. Ambos abordajes se combinaron simultáneamente.

Resultados

Se lograron nefroureterectomías con desinserción endoscópica del rodete vesical en bloque, garantizando un sistema cerrado, comparable con la técnica abierta. El segundo caso precisó reconversión por problemas técnicos y prolongación del tiempo quirúrgico. No se diagnosticaron recidivas durante el seguimiento.

Conclusión

Los resultados alcanzados son comparables con los de la cirugía abierta y la técnica garantizó el cumplimiento de los principios oncológicos. Permitió la desinserción en decúbito lateral evitando el reposicionamiento del paciente, ahorrando tiempo quirúrgico. Los resultados reflejaron los beneficios de la cirugía mínimamente invasiva en todos los casos.
