Background: Percutaneous Nephrolithotomy (PCNL) has revolutionized the treatment of large renal and proximal ureteric stones, offering a minimally invasive alternative to open surgery. The introduction of tubeless PCNL, which omits the placement of a nephrostomy drainage tube, has generated discussion regarding its efficacy and safety compared to the traditional tubed PCNL.
Objective: This study aims to compare the outcomes of tubed versus tubeless PCNL in terms of post-operative complications, recovery time, and efficacy in stone removal.
Methods: A retrospective cross-sectional analysis was conducted on 110 patients who underwent PCNL at the Institute of Kidney Disease, Peshawar, from January 2017 to December 2020. Patients were allocated into two groups, tubed PCNL (n=50) and tubeless PCNL (n=50), based on 1:1 sequential randomization. The inclusion criteria were ASA I and ASA II classification, age between 5 to 70 years, and single tract procedure with complete clearance without the need for a second look nephrostomy. Exclusion criteria included patients with a solitary kidney, active urinary tract infections, and congenital malformations. Data on age, gender, co-morbidities, history of ESWL, stone size, location, quantity, and post-operative outcomes were collected and analyzed using SPSS version 25.
Results: No significant differences were found in patient demographics or stone characteristics between the two groups. The tubeless PCNL group demonstrated a significantly lower rate of post-operative ESWL sessions (4% vs. 22%, p=0.02) and a trend towards shorter hospital stays, although not statistically significant. The drop in hemoglobin levels post-operation was less in the tubeless group (0.84 ± 1.87 mg/dl) compared to the tubed group (1.56 ± 0.91 mg/dl), but this was not statistically significant (p=0.17).
Conclusion: Tubeless PCNL offers a viable alternative to traditional tubed PCNL, particularly for patients with smaller renal stones. It is associated with a lower need for post-operative ESWL sessions and potentially shorter hospital stays, suggesting an advantage in terms of recovery and post-operative comfort. Further prospective studies are warranted to confirm these findings and explore the long-term outcomes of the tubeless technique.
