Abstract:
Purpose
To compare outcomes in two groups of patients with kept and discarded nephrostomy tube after percutaneous nephrolithotomy (PCNL) complicated with bleeding. Materials And Methods
Two hundred patients who had undergone PCNL complicated with hemorrhage were recruited in this study. Patients were randomly allocated to two groups: group A, who underwent tubeless PCNL and tract port was packed for 3 to 4 minutes after removing Amplatz sheath, and group B, for whom a 24-F nephrostomy tube was left in place at the end of the procedure. Patients were followed up for 3 months to check if bleeding occurred. Results
The mean operation time was 68 ± 4.3 minutes in group A and 74 ± 5.6 minutes in group B (P =. 098). The mean stone size was similar in groups A and B (36.26 ± 5.3 mm versus 35.35 ± 5.85 mm; P =. 613). The mean hemoglobin drop was 3.65 ± 1.20 g/dL in group A and 3.13 ± 1.06 g/dL in group B. There was no significant difference between the mean of stonefree rate in groups A and B (92.58% ± 5.97 versus 89.60% ± 8.3; P =. 210). Patients in group A experienced a significantly less duration of hospitalization than group B (2.42 ± 0.84 days versus 3.70 ± 0.80 days; P <. 001). Conclusion
In the absence of clear indication, nephrostomy tube insertion after PCNL does not seem to be beneficial, and its removal does not pose patients at any additional risk.Language:
