Percutaneous Nephrolithotomy in Patients with Renal Calculi at Yasothorn Hospital during 2012 – 2013 and Nakhonphanom Hospital during 2017 – 2019

Abstract

Background : Percutaneous nephrolithotomy is the effective treatment for renal calculi not over than 4 centimeter in size.

Objective : This study aimed to evaluate clinical outcomes of Percutaneous Nephrolithotomy.

Method : The study was a retrospective descriptive study to evaluated clinical outcomes of Percutaneous Nephrolithotomy in patients with pelvic, calyceal or partial staghorn stones at Yasothorn Hospital in 2012-2013 and Nakhonphanom Hospital in 2017-2019

Result : Percutaneous Nephrolithotomy treatment in 60 patients, 32 patients (53%) were male. Mean age of patients were 45.2 years old (25-60). The location of stones were 50 pelvic stones, 7 calyceal stones and 7 partial staghorn stones. The size of stones were less than 2 centimeters in 12 patients, 2 to 4 centimeters in 41 patients, over 4 centimeters in 7 patients. Range of operative times were from 45 to 110 minutes (mean 81 minutes), range of radiation exposure time were from 60-130 seconds (mean 90 seconds.). Four patients had hemorrhagic problems and need blood transfusions. Range of hospital stayed were from 5 to 10 days (mean 7 days). There had postoperative fever in 5 patients, and one patients had urosepsis, and solved by antibiotic treatments. Outcomes of percutaneous nephrolithotomy were no residual stone 40 patients (67%), had residual stone less than 5 millimeters in diameter 15 patients (25%) and 5 patients (8%) had 5-10 millimeters stones in diameter needed to treated by ureteroscopic lithotripsy or repeat percutaneous nephrolithotomy.

Conclusion : Percutaneous nephrolithotomy is the effective treatment for renal calculi and provide safety outcomes. More surgical practice could improve stone free rate and decrease the relevant post-operative complication.
