VARGAS ROCHA, Vladimir Erik  y  ROJAS ZARATE, Abel. Partial Nephrectomy laparoscopic of single functional kidney "Renal 12xh", case presentation and literature review. Gac Med Bol [online]. 2023, vol.46, n.1, pp.113-116.  Epub 01-Jun-2023. ISSN 1012-2966.

Nephron-sparing surgery (partial nephrectomy) has provided multiple benefits, mainly in patients with small kidney lesions or concomitant diseases that affect overall kidney function in long term, also in patients with a single functional kidney, either congenital or by surgery, end-stage renal disease, bilateral renal tumors or with chromosomal diseases that affects the renal function. The case of a 52-years-old male patient is presented with a 10-cm right kidney tumor in the interpolar region, with not functional left kidney exclusion due to an obstructive process by congenital ureteropyelic stenosis. Right nephron-sparing nephrectomy was performed despite the location and size of the tumor, obtaining excellent oncological and functional results. Follow-up at twelve months of postoperative evolution showed no data of tumor activity, presenting renal function with creatinine of 1.6 mg/dl, with satisfactory evolution.


Partial nephrectomy is the standard management for small-volume renal tumors located in the renal cortex and polar areas, or not functional contralateral kidney; but there is the dilemma, when patients appear with impaired renal function or tumors located near the renal hilum by > 5 cm of diameter, the risk of performs this procedure must be taken, the laparoscopic approach is an excellent option. with great results, and minor bleeding than open surgery.
