“…When the methods were compared in terms of complications, it was reported that micro-PNL caused fewer complications (13.3%) than RIRC (16.6%); however, the difference between these two groups was not statistically significant (p=0.675). When micro-PNL was compared with mini-PNL, another minimally invasive method, it was reported that the success rates were 87.3% and 93.6%, respectively (22). In addition to similar success rates, other advantages of micro-PNL over mini-PNL reported in the same study were that micro-PNL results in smaller decreases in hemoglobin levels and shorter hospital stays.…”

Furthermore, micro-PNL, the newest PNL method, enables visual entry in a single session via a special puncture needle, called an "all-seeing needle", by means of a micro-optical imaging system; this method does not require dilation because the nephroscope can be as fine as 4.8 Fr (13,14). This new method not only avoids dilation, which may cause complications such as hemorrhage and perforation, but also shortens operation and fluoroscopy times (14). Micropercutaneous Nephrolithotomy: First 66 Cases ExperienceObjective: To present the initial experience with micro-percutaneous nephrolithotomy (micro-PNL) in patients with kidney stones.Methods: Medical records of 66 patients with kidney stones who underwent micro-PNL between December 2012 and March 2015 were retrospectively reviewed. The demographic data; stone side, location and size; operation and fluoroscopy time; intraoperative and postoperative complications; preoperative and postoperative hemoglobin levels and hematocrit; and operation success of the patient were evaluated. Results:The mean age of the patients was 46.62±13.94 years, and their mean body mass index was 25.77±2.62 kg/m 2 . The mean stone size was 186.7±34.23 mm 2 . The mean operation and fluoroscopy times were 80.46±43.67 min and 10.78±7.14 min, respectively. The mean hemoglobin drop was 0.86 g/dL. Twenty-four intraoperative and 17 postoperative complications were observed. An overall success rate of 95% (including clinically insignificant residual fragments) was achieved. Conclusion:Micro-PNL is a feasible, safe, and effective minimally invasive treatment modality for patients with small kidney stones.

“…In the case of percutaneous nephrolithotomy with visual nephroscopy (F4.8 ultramicro channel), intrapelvic pressure is significantly higher than that in the case of a standard channel, which can increase the risk of infection. Research by Karatag et al 19 has demonstrated the relative safety of this approach if the intrapelvic pressure is lower than 30 mmHg. Therefore, it is desirable to reduce intrapelvic pressure, shorten the duration of surgery, and reduce the risk of infection by establishing a standard channel in the case of large renal calculi.…”

To study the safety and efficacy of standard channel establishment using a visual puncture system in the treatment of renal calculi without hydronephrosis. Methods: We retrospectively analyzed data from 46 patients undergoing percutaneous nephrolithotomy via a standard channel assisted by a visual puncture system, including number of punctures, duration of procedure, hemoglobin level after surgery, calculi clearance rate, and postoperative complications. Results: Sixty-nine channels were established, including a single channel in 26 cases, double channel in 17 cases, and three channels in 3 cases. The mean number of punctures was 1.50, mean time to establish the standard channel was 2.6 minutes, and duration of surgery was 31.3 minutes. No significant change in hemoglobin was observed after surgery. Forty-three patients had no residual calculi and three had small residual calculi on the day after surgery, representing a first-phase clearance rate of 93.48% (43/46). No significant complications were observed. Conclusions: Hemorrhage during operation can be significantly reduced by establishing a standard channel using a visual puncture system. Moreover, the number of standard channels can be reduced and the incidence of complications lowered using this approach, which should be adopted widely for the treatment of renal calculi without hydronephrosis.

ÖzetAmaç: Pediatrik hastalarda böbrek taşlarınının cerrahi tedavisinde mikro-PERC'nin etkinliğini ve güvenilirliğini araştırmayı amaçladık.. Gereç ve AbstractObjective: We aimed to investigate the efficacy and safety of micro-PERC in the surgical treatment of kidney stones in pediatric patients. Materials and methods:We reviewed the data of 32 pediatric patients who underwent micro-PERC for pediatric renal stone disease between January 2015 and January 2017 in our clinic retrospectively. The duration of operation, duration of fluoroscopy, length of hospital stay, complication rates and stone free rates were recorded. Results:The mean age of the 32 patients was 5 ± 4.1 (1-10) years, and the mean stone size was 13.35 ± 3.12 mm. The duration of operation was 74.2 ± 14.2 minutes, while the mean duration of fluoroscopy was 109 ± 31.2 seconds. Conclusion:: Minimally invasive methods such as micro-PERC are effective and reliable treatment methods in children.
