Comparison between Standard Percutaneous Nephrolithotomy versus Tubeless Percutaneous Nephrolithotomy

Abstract

Background: Percutaneous nephrolithotomy (PCNL) technique has become a routine treatment for upper urinary calculi. Objectives: To describe the socio-demographic characteristics of the patients and to compare the outcome of operated patients. Materials And Methods: This was a retrospective study, of patients underwent PCNL in our Urology Center, between January 2020 and December 2022. Data of age, side, location of stone, size of stone, operating time, hospital stay, post operation pain, residual stones, fever, fistula, blood transfusion, and postoperative infection were recorded and compared between the two groups. Data were analyzed by using the SPSS version 22. Independent t-tests were used to analyze continuous variables, while for categorical variables chi-square test was used to compare two groups and a p value of less than 0.05 was determined as statistically significant. Results: 51.1% of the patients were females and 48.9% were males, (P = 0.000). The mean age was 38.1 ± 11.1 years. The highest number of patients were in the age group 30 – 39 years (40.0%), (P = 0.000). The location of stones was in pelvic (48.9%), lower calyces (30.0%) and pelvic + lower calyces (21.1%), (P = 0.000). Pain was more common as moderate in both groups PCNL (42.2%). Residual stones were (23.4%) only in standard PCNL group, (P = 0.000). Fever was in (7.8%) standard PCNL and in tubeless PCNL was in (2.2%), (p = 0.045). Blood transfusion was provided to (5%) for the standard PCNL patients and (3.3%) for tubeless PCNL patients. Patients who had standard PCNL had postoperative infectious (2.2%) was found in standard PCNL patients. Mean operation-time and mean hospital stay of standard PCNL was predominant. Conclusion: Tubeless PCNL proved to be the safest and most effective. Keywords: Comparison, standard, tubeless percutaneous, nephrolithotomy.
