Aim: To evaluate the safety and efficacy of ultrasound-guided percutaneous nephrostomy (PCN) placement in pregnancy. Method: Medical records of 26 pregnant patients who were inserted with a total of 27 PCN catheters between June 2020 to June 2023 were retrospectively analyzed to assess imaging findings, procedural parameters, technical success, delivery outcomes, and procedural complications. Results: At the time of placement of the PCN, the mean gestational age was 29.04±7.01 weeks (range 7 - 36 weeks). The indications for insertion of the PCN catheter included: 1) obstructing calculi (46.2%), 2) pyelonephritis (34.6%), and 3) symptomatic hydronephrosis without calculi (19.2%). Successful catheter placement was achieved in 25/27 procedures, yielding a success rate of 92.59%, and no major complications. Minor instances of transient hematuria were encountered in three cases. The mean duration of catheter retention was 72.58 days. All patients exhibited significant clinical and symptomatic improvement. Among these patients, 22 patients (84.6%) delivered their babies at full-term, 3 patients (11.5%) delivered prematurely, and 1 patient (3.8%) experienced a miscarriage. Conclusion: Ultrasound-guided PCN placement is a reliable method with high success and efficacy that can be applied during pregnancy. This procedure avoids the use of ionizing radiation, ensuring safety for both the fetus and the mother.
