Introduction

The success of peritoneal dialysis (PD) depends on the timely and appropriate placement of a peritoneal catheter (PC). The lack of access to PC placement and the presence of early complications after placement are barriers to the development of the PD. The nephrologist's percutaneous placement of the PC offers a solution to some of these problems and when performed systematically and with proper patient selection, it is a safe technique. The objective of this study is to describe the experience of percutaneous PC placement by nephrologists at a university peritoneal dialysis center, evaluate complications related to the procedure, and complications (early and late) associated with PC use.

Methods

Retrospective and observational study. Patients aged 18 and older who chose PD as a renal replacement technique between January 2018 and September 2023 and had a PC placed for this purpose were included. The analysis separated patients into a percutaneous placement group and a laparoscopic placement group. Percutaneous placement was performed by the same team of nephrologists, and laparoscopic placement was conducted by the same team of surgeons. All catheters were placed in a surgical block and received sedation or anesthesia based on the anesthetist's assessment. Clinical and analytical data, as well as early or late complications related to the different techniques, were recorded. Complications were categorized as mechanical or infectious. Complications occurring within 4 weeks after PC placement was considered "early complications".

Results

A total of 111 PCs were placed during the study period, with 63 (56%) using percutaneous placement and 48 (44%) using laparoscopy. Table 1 shows the characteristics of the study population.

Conclusions

Nephrologists' percutaneous PC placement is a safe technique with a low prevalence of complications. The lack of dependence on other actors allows for faster access. Proper patient selection (more complications in obese and polycystic patients) is important to minimize complications. Surgical techniques like laparoscopy are necessary for patients at higher risk of complications or those requiring other concurrent surgical treatments
