    OBJECTIVE To compare outcomes of micro-percutaneous nephrolithotomy (PNL; microperc) with mini-PNL (miniperc) in the treatment of pediatric renal stones of sizes 10-20 mm. MATERIALS AND METHODS Patients aged <18 years who underwent PNL for renal stones of sizes 10-20 mm between August 2011 and March 2014 in 3 referral centers were reviewed retrospectively. Patients were evaluated in the following 2 groups: microperc (group 1) and miniperc (group 2). Demographics and perioperative parameters (fluoroscopy and operation time, hemoglobin drop, and stone-free and complication rates) were retrospectively analyzed. RESULTS A total of 119 patients were evaluated, including group 1 (n = 56) for microperc and group 2 (n = 63) for miniperc. We found mean stone sizes as 13.4 +/- 3.4 and 14.8 +/- 3.7 mm in the groups, respectively (P = .046). Mean operation and fluoroscopy times were 57.1 +/- 31.2 minutes and 132.4 +/- 92.5 seconds in the microperc group and 68.9 +/- 36.7 minutes and 226.2 +/- 166.2 seconds in the miniperc group, respectively (P = .110 and P <. 001). Stone-free rates were similar in both groups (82.1% vs 87.3%; P = .433 and 92.8% vs 93.6%; P = 0673) on postoperative day 1 and at first-month follow-up. The mean hemoglobin drop in group 2 differed from that in group 1 significantly (P <. 001). The difference of average hospitalization times was statistically significant (43.0 +/- 15.4 vs 68.5 +/- 31.7 hours; P <. 001). CONCLUSION Our outcomes show that microperc may be preferred as an alternative to mini-PNL for the treatment of pediatric kidney stones of sizes 10-20mmwith comparable success and complication rates, as well as shorter hospitalization and fluoroscopy times.

    Does aging affect the outcome of percutaneous nephrolithotomy?
    (Springer, 2015) Buldu, Ibrahim; Tepeler, Abdulkadir; Karatag, Tuna; Bodakci, Mehmet Nuri; Hatipoglu, Namik Kemal; Penbegül, Necmettin; Akman, Tolga
    To investigate whether aging affects surgical outcomes by comparing the results of two patient groups undergoing PNL: those over 60 and those under 60. A retrospective screen was made for patients undergoing conventional PNL surgery for renal stones performed in two separate centers between 2010 and 2013. 520 patients included were classified into age groups: patients aged 18-59 comprised Group-1 and those aged over 60 comprised Group-2. Those between 60-69 years (sexagenarian) were assigned to Group-2a; 70-79 years (septuagenarian) to Group-2b; and 80-89 years (octogenarian) to Group-2c. Patients' demographic characteristics (accompanying comorbidities, ASA scores, body mass indices and stone size) and perioperative values (duration of surgery and hospital stay, success and complication rates) were compared between the groups. Mean stone size was similar in groups (30.1 +/- 15.5 vs. 31.5 +/- 15.4 mm, p = 0.379). The mean ASA value for the patients in Group-1 was 1.61; significantly lower than that in the other groups (p = 0.000). The level of accompanying comorbidities in Group-1 was significantly lower than that of the other groups (p = 0.000). The mean duration of surgery, postoperative hematocrit drop, complication and success rate were statistically similar in Groups 1 and 2 (p = 0.860, p = 0.430, p = 0.7, and p = 0.66, respectively). The duration of hospital stay was significantly shorter in the patients in Group-1 compared to those in Group-2 (p = 0.008). In experienced hands, PNL can be safely and reliably performed in the treatment of renal stones in elderly patients.
