Clinical study on percutaneous nephrolithotomy(PCNL) with laparoscopy assisted and retrograde intrarenal surgery(RIRS) for treatment of renal calculi in pelvic ectopic kidney
2019
Objective
To explore the clinical efficacy of percutaneous nephrolithotomy(PCNL) with laparoscopy assisted and retrograde intrarenal surgery(RIRS) for treatment of renal calculi in pelvic ectopic kidney.
Methods
From January 2016 to October 2017, PCNL with laparoscopy assisted or RIRS were performed in 6 patients with calculi in pelvic ectopic kidney. Patient's demographics and perioperative characteristics (including age, sex, side of pelvic kidney, stone size, stone number, stone location, special medical history), operative and post-operative related details (including tract size, operation time, trocars, nephrostomy tube, abdominal drainage tube, double J stent, stone free, hospital stay) were reviewed.
Results
The mean operation time of PCNL with laparoscopy assisted and RIRS were 92 min and 85 min respectively, and the mean stone size were 19 mm and 12 mm respectively. In addition, the mean hospital stay time of RIRS was 3 days and less than that of PCNL with laparoscopy assisted (5 days), and the success rate were 60%(3/5) and 100%(3/3) respectively. None had serious complications and residual calculi.
Conclusions
Both PCNL with laparoscopy assisted and RIRS are safe options in the management of patients with renal calculi in pelvic ectopic kidney. RIRS has advantages in invasion and hospital stay, and PCNL with laparoscopy assisted has the ability to deal with bigger stones and more complex situations with a higher success rate.
