Outcomes of large bore vs small bore percutaneous nephrolithotomy
Objective: To determine postoperative results of large bore vs small bore PCNL.
Design and duration: This is a prospective study. It was started in November 2018 and completed in April 2019 after 6 months duration.
Setting: Study was conducted in Kidney center of Bahawal Victoria Hospital Bahawalpur.
Patients and Methods: Patients having kidney stones and ideal for PCNL were distributed in two groups in randomized way. Group-1 patients underwent small bore PCNL and those in group-2 underwent large bore PCNL. There was equal number of cases in each group. Both male and female patients were included in the study. Mean duration of stay in hospital was 7±3 days. All data collected was analyzed using SPSS and Microsoft office version 2016. Results were calculated in the form of frequencies and percentages and averages. Tables and Graphs used to present data. Consent was taken from ethical committee of the study hospital and consent was also taken from all cases in study group.
Results: There were total 90 cases in this study distributed in two groups each containing 45 cases. There were 37 female and 63 male cases. Mean age of patients was 33.5±5 years. Mean anesthesia time was 1.5±0.5 hours in both groups. Mean analgesia given in group-1 was 100±50 mg .
Conclusion: In our study small bore PCNL was proved to be better than large bore PCNL associatd with least complications and early recovery with less hospital stay and less use of analgesia.
