Transperitoneal laparoscopic simple nephrectomy for giant hydronephrosis: Tips and tricks to make it easier

Area of Science:

• Urology
• Minimally Invasive Surgery
• Nephrology

Background:

• Giant hydronephrosis (GH) presents a significant surgical challenge.
• Traditional open nephrectomy (ON) can be associated with considerable morbidity.
• Laparoscopic nephrectomy (LN) offers a minimally invasive alternative.

Purpose of the Study:

• To evaluate the feasibility, safety, and efficacy of transperitoneal laparoscopic nephrectomy (LN) for giant hydronephrosis (GH).
• To compare the outcomes of LN with traditional open nephrectomy (ON) for GH.

Main Methods:

• Retrospective analysis of 88 patients with GH treated between October 2015 and December 2019.
• Patients underwent either transperitoneal laparoscopic nephrectomy (LN, n=38) or open nephrectomy (ON, n=50).
• Outcomes including operative time, complications, pain scores, and hospital stay were compared.

Main Results:

• Mean operative time was longer for LN (195 min) compared to ON (127 min) (p=0.01).
• Estimated blood loss was significantly greater in the ON group (p=0.01).
• Visual analog pain scores were significantly higher in the ON group on postoperative days 1 and 2 (p=0.01).

Conclusions:

• Transperitoneal laparoscopic nephrectomy (LN) is a feasible, safe, and effective surgical option for giant hydronephrosis (GH).
• The laparoscopic approach is associated with decreased morbidity, shorter hospital stays, and quicker recovery compared to open nephrectomy (ON).
• Refinements in technique can potentially reduce operative time for LN in GH cases.
