Resumen

El intestino es usado en cirugía urológica para sustituir la vejiga a modo de un conducto que drene orina a la pared abdominal o remodelado para formar una vejiga de sustitución o ampliación.

Muchos factores contribuyen a la formación de litiasis siendo los más importantes el éstasis urinario, producción de moco y la bacteriuria. Las alteraciones metabólicas inducidas por la exposición de segmentos intestinales en el tracto urinario promueve la formación de cálculos de estruvita, oxalato cálcico y fosfato cálcico.

Generalmente, la mayoría de pacientes con litiasis en derivaciones urinarias, pueden ser tratados con técnicas mínimamente invasivas. La extracción mediante cirugía abierta es considerada cuando otras modalidades de tratamiento no pueden ser efectuadas de forma segura y expeditiva.

Abstract

Bowel is used in urological surgery to replace the bladder, either as a conduit to drain urine to the abdominal wall as a urinary stoma or refashioned to form a substitute bladder.

Many factors contribute to stone formation, being urinary stasis, mucus production and bacteriuria the most important. Metabolic changes induced by exposure of segments of the alimentary tract to urine promote struvite, calcium oxalate and calcium phosphate stone formation.

Generally, the majority of patients with stones in a urinary diversion can be treated with minimally invasive techniques. Open surgical removal is considered when other modality of treatments cannot be accomplished safely and expediously.
