Objective:
To present our clinical experiences with micropercutaneous nephrolithotomy in the treatment of moderate-sized renal calculi from a single center.
Methods:
We retrospectively evaluated the patients with moderate-sized renal calculi who underwent micro-percutaneous nephrolithotomy between December 2012 and Septermber 2013.
Results:
A total of 68 patients and 70 renal units underwent microperc procedure. Mean age of patients was 41.4 ± 18.8. The mean stone size was 122 ± 83 mm(2). The operations were performed under spinal anesthesia in 89.7% of the patients. Stone-free rate was 95.7 % (67/70). Clinically significant residual fragments were observed in three patients. The average duration of operation and mean fluoroscopy time was 40 ± 23 min and 108 ± 72 s, respectively. The mean postoperative drop in hemoglobin was 0.95 ± 0.7 while no patient required blood transfusion. Patients were discharged after an average hospitalization time of 27.5 ± 12.4 h. A total of 4 complications (5.7%), including urinary tract infection (Clavien I) in one patient and renal colics requiring stent insertion (Clavien IIIa) in three patients, were observed postoperatively.
Conclusion:
Microperc technique is safe, feasible, and efficacious. We suggest that micro-percutaneous nephrolithotomy should be considered for the treatment of moderate-sized renal stones as an alternative to SWL and RIRS failures and also may be considered even primarily.
Insights
Micropercutaneous nephrolithotomy (microperc) is a safe and effective treatment for moderate-sized kidney stones. This study shows a high stone-free rate with minimal complications, suggesting it as a primary option.
Area of Science:
- Urology
- Minimally Invasive Surgery
Background:
- Renal calculi (kidney stones) management often requires effective and minimally invasive techniques.
- Micropercutaneous nephrolithotomy (microperc) offers a less invasive approach for stone removal.
Purpose of the Study:
- To evaluate the clinical outcomes of micropercutaneous nephrolithotomy for moderate-sized renal calculi.
- To assess the safety and efficacy of the microperc technique in a single center.
Main Methods:
- Retrospective evaluation of patients undergoing microperc for moderate-sized renal calculi.
- Data collected included patient demographics, stone size, operative details, stone-free rates, and complications.
Main Results:
- A total of 68 patients (70 renal units) were treated with microperc.
- The stone-free rate was 95.7%, with a mean stone size of 122 mm².
- Complications were low (5.7%), including urinary tract infection and renal colic requiring stent insertion.
Conclusions:
- Micropercutaneous nephrolithotomy is a safe, feasible, and effective procedure for moderate-sized renal stones.
- Microperc can be considered as an alternative to shock wave lithotripsy (SWL) or retrograde intrarenal surgery (RIRS) failures, and potentially as a primary treatment.
