It is considered that laparoscopic single-site surgery should be performed by specially trained surgeons because of the technical difficulty in using special instruments through limited access. We investigated suitable patients for single-port laparoscopic radical nephrectomy, focusing on the anatomy and distribution of the renal artery and vein.
This retrospective study was conducted in 52 consecutive patients who underwent single-port radical nephrectomy by the transperitoneal approach.

Adequate operation interspace is the premise of laparoscopy, and carbon dioxide (CO2) was an ideal gas for forming lacuna. A retroperitoneal space is used to form operation interspace in retroperitoneal laparoscopic radical nephrectomy by making ballooning, and the retroperitoneal space has no relative complete and airtight serous membrane, therefore CO2 absorption may be greater in retroperitoneal than transperitoneal laparoscopic radical nephrectomy. Excess CO2 absorption may induce hypercapnemia and further cause physiopathological change of respiratory and circulatory system.

Radical nephroureterectomy is considered as the gold standard for the surgical treatment of upper urinary tract urothelial carcinoma (UTUC). Laparoscopic radical nephroureterectomy (LNU) can be performed via the transperitoneal (TLNU) or retroperitoneal (RLNU) approach, and each one has its own advantages and limitations. Our study was conducted to describe the difference between TLNU and RLNU by comparing the perioperative outcomes.

Looking for a virtually "scarless" surgery mini-laparoscopy (ML) could be a viable alternative to conventional laparoscopy. ML is a reproducible technique and allows for the preservation of the triangulation concept, the cornerstone of laparoscopic surgery. Drawback of ML could be the poor performance of miniaturized instruments that could affect the confidence of the surgeon and limit the indications.

The standard treatment for the muscle-invasive bladder cancer (MIBC) adheres to the open radical cystectomy (RC), although in the last few years the RC was established in some centres. The MIBC with simultaneous renal pathology (carcinoma, loss of function) can be a reason for an RC in combination with a nephrectomy. In the present paper we give a report about our first 3 patients in whom we combined the robotic RC with a laparoscopic nephrectomy as a minimally invasive treatment.

For the treatment of localised renal cell carcinoma (RCC), uncertainties remain over the perioperative and quality-of-life (QoL) outcomes for the many different surgical techniques and approaches of nephrectomy. Controversy also remains on whether newer minimally invasive nephron-sparing interventions offer better QoL and perioperative outcomes, and whether adrenalectomy and lymphadenectomy should be performed simultaneously with nephrectomy. These non-oncological outcomes are important because they may have a considerable impact on localised RCC treatment decision making.

Laparoscopic radical nephrectomy should be executed under the most fundamental principle of early ligature of the renal artery to prevent diffusion of cancerous cells. This is extremely true in the treatment of large renal tumors touching the main renal vasculature. Obviously, the concomitance of a duplicated inferior vena cava (IVC) with associated aberrant tributaries will significantly increase the surgical difficulty and the procedural risk of vascular injury.
