Purpose:
In this study, we report our initial experience using microperc for treatment of kidney stones and the implications of the microperc system in bladder stone management.
Patients And Methods:
Microperc was performed with a 4.85F "all-seeing needle" in 11 patients with stone disease; 9 of the patients had kidney stones and 2 had bladder stones. Access to the renal collecting system was achieved under fluoroscopic control in eight patients, while ultrasonography was used in one. Fluoroscopy was not used in any of the patients with bladder stones for bladder access.
Results:
The mean stone burden was 12.8 mm (range 7-18 mm). The stone locations were pelvis in three, upper calix in one, middle calix in two, and lower calix in three. The mean age for kidney stones was 20.8 years (range 3-47 years). Single access was sufficient in all cases. In two patients, although the procedure was progressing without complication, conversion to miniperc was needed because of operator-related system errors. There were no intraoperative complications. The stone-free rate in the postoperative first month was 85%.
Conclusion:
The least invasive microperc with an optical puncture system appears to be a safe and effective treatment modality in patients with different kinds of stone disease with respect to various features. Although the initial cases were patients with single stones of less than 20 mm, the combined use of this system with other minimally invasive treatment modalities for the management of larger stones is promising.
Insights
MicroPerc, a minimally invasive technique, effectively treated kidney and bladder stones in 11 patients. This approach demonstrated an 85% stone-free rate within one month, showing promise for stone disease management.
Area of Science:
- Urology
- Minimally Invasive Surgery
- Nephrolithiasis Management
Background:
- Kidney and bladder stones pose a significant clinical challenge.
- Minimally invasive surgical techniques are continually evolving for stone disease treatment.
Purpose of the Study:
- To evaluate the initial clinical experience with microPerc for kidney and bladder stone treatment.
- To assess the implications of the microPerc system in managing various stone burdens and locations.
Main Methods:
- MicroPerc, utilizing a 4.85F "all-seeing needle", was performed on 11 patients (9 kidney stones, 2 bladder stones).
- Renal access was achieved via fluoroscopy (8 patients) or ultrasonography (1 patient).
- Bladder access for bladder stones did not utilize fluoroscopy.
Main Results:
- The mean stone burden was 12.8 mm, with stones located in the renal pelvis, upper, middle, and lower calices.
- Single access was sufficient for all patients.
- An 85% stone-free rate was achieved at the one-month follow-up.
- No intraoperative complications occurred, though two cases required conversion to miniPerc due to system errors.
Conclusions:
- MicroPerc, a minimally invasive optical puncture system, is a safe and effective treatment for diverse stone diseases.
- While initial cases involved smaller stones, combined use with other modalities shows promise for larger stone management.
