[Partial laparoscopic nephrectomy: treatment for hydrocalicosis due to infundibular stenosis]

This report describes a partial nephrectomy with a minimally invasive approach, carried out laparoscopically as a treatment for a hydrocalicosis caused by a congenital infundibular stenosis.

The patient presented a clinical background of one year of evolution, manifested as recurrent urinary tract infections caused by urine accumulation in the adjacent collecting tubules which were compressed by the superior hydrocalicosis. This procedure was made using a transperitoneal access, making a superior pole resection of the right kidney and respecting the adrenal gland.

In our opinion, to widen the usage of the laparoscopic surgery in urology can benefit patients to reduce post-surgery complications and hospitalization time, with a more comfortable recovery.
