Tubeless percutaneous nephrolithotomy (PCNL) reduces hospital stays and pain medication requirements in children compared to traditional tubed procedures.
A study examining 102 pediatric patients found that removing the nephrostomy tube did not compromise stone-free outcomes, suggesting a viable path for optimizing pediatric urological recovery.
- Less Pain: Children who did not have a drainage tube required fewer doses of pain medication during their recovery.
- Shorter Hospitalization: Patients were discharged sooner, with the tubeless group averaging 3.63 days compared to 6.14 days for the tubed group.
- Equal Effectiveness: Both surgical methods achieved nearly identical success rates in clearing stones, with 96% of patients in both groups classified as stone-free at three months.
Percutaneous nephrolithotomy is a standard for managing renal calculi in children, yet the traditional use of a nephrostomy tube—a catheter placed directly into the kidney to provide drainage—often contributes to postoperative discomfort. Researchers at the Veer Surendra Sai Institute of Medical Sciences and Research in Odisha, India, conducted a prospective study between July 2023 and June 2024 to determine if this tube could be safely omitted.
The study, which received institutional ethics approval in June 2023, compared 51 children undergoing the conventional tubed procedure against 51 undergoing the tubeless approach. While both groups experienced no instances of urinary leakage or perinephric collection, the tubeless cohort had a faster surgical process and lower analgesic consumption. The mean operative time was 97.22 minutes for the tubeless group, compared to 99.35 minutes for those who received the tube.
The data suggests that the decision to forgo a nephrostomy tube is highly dependent on intraoperative findings. Surgeons in the study adhered to strict criteria for the tubeless approach, ensuring it was only performed when there was no evidence of significant bleeding or damage to the pelvicalyceal system—the internal structures of the kidney where urine collects.
This surgical approach is not universal. The study explicitly excluded children with complex anatomical abnormalities, such as horseshoe kidneys or severe spinal curvature (kyphoscoliosis), as well as those with active preoperative urinary tract infections. Clinicians emphasize that if there is any evidence of significant collecting-system injury or profuse intraoperative bleeding, the placement of a nephrostomy tube remains the safer standard of care to ensure adequate drainage and prevent complications.
These specialists determine the necessity of PCNL based on factors including stone size, with this study focusing on children with renal calculi measuring 1.5 to 2.5 cm for this minimally invasive intervention.
The study was conducted as a prospective comparative analysis, reflecting the evolving clinical preference for minimizing invasive drainages in pediatric populations where pain management and rapid recovery are paramount.
