Abstract Corresponding Background Stone size is a key factor in the determination of the success of author: treatment modalities. Recently, there has been a great advancement in technology for minimally invasive management of urinary stones such as percutaneous nephrolithotomy, ureteroscopy, shockwave lithotripsy, and retrograde internal Surgery Aim of the Work to compare the outcome of PCNL and RIRS in medium sized renal pelvic stoned in adults regarding operative time, fluoroscopic time, intra and postoperative complications, stone free rate, hospital stay and postoperative stenting. Patients and Methods This prospective randomized clinical study was conducted on 30 patients from April 2019 to January 2020, all patients had single renal pelvic stone (10 to 20 mm) and had no contraindication to perform these operations at the Urology department, Ain Shams University Hospitals and National Institute of Urology and Nephrology. The patients were randomized by (1 : 1) manner for either PCNL or RIRS. All preoperative, intraoperative and postoperative parameters, results and complications between both groups were recorded. Results Mean fluoroscopic time and hospital stay were significantly greater in PCNL group than RIRS group. The stone free rate was 86.7% (13/15) in PCNL group and 80% (12/15) in RIRS group and for complications (according to Cliven-Dindo score) there were no statistically significant difference between two groups.Complications occurred in 3(20%) patients in PCNL group and in 2(13.3%) patients in RIRS group. PCNL and RIRS are safe and effective methods for medium sized renal pelvic stones. For selected patients, RIRS may represent an alternative therapy to PCNL, with acceptable efficacy and low morbidity. RIRS compared to PCNL offers the best outcome in terms of radiation exposure and hospital stay. Conclusion RIRS may represent an alternative therapy to PCNL, RIRS compared to PCNL offers the best outcome regarding radiation exposure and hospital stay.

Staghorn Stones

Introduction: We compare percutaneous nephrolithotomy (PCNL) and open surgery in the treatment of staghorn stones in children.Methods: We retrospectively reviewed the electronic records of children who underwent treatment for staghorn stones between September 2000 and August 2013. They were divided between Group 1 (patients who underwent PCNL) and Group 2 (patients who underwent open surgery). We compared stone-free and complications rates, need for multiple procedures, and hospital stay.Results: The study included 41 patients (35 boys and 6 girls), with mean age 7.4 ± 3.1 years (range: 2–15). Of these 41 patients, 26 had unilateral renal stone and 15 had bilateral renal stones. The total number of treated renal units was 56: 28 underwent PCNL and 28 underwent open surgery. The complication rate was comparable for both groups (32% for open surgery vs. 28.6%, p = 0.771). Multiple procedures were more needed in PCNL group (60.7% vs. 32% in open surgery, p = 0.032). The stone-free rate was 71.4% after PCNL and 78.6% after open surgery (p = 0.537). A significant difference was observed in shorter hospital stay after PCNL (5 vs. 8.8 days, p < 0.001). Our study’s limitations include its retrospective design and relatively small sample size.Conclusions: For the treatment of staghorn stones in children, PCNL was comparable to open surgery in complication and stone-free rates. PCNL had the advantage of a shorter hospital stay and open surgery showed a decreased need for multiple procedures.

Background: The decision for using supine or prone position in percutaneous nephrolithotomy (PCNL) is still debatable. The aim of this study is to compare the efficacy and safety profile of the supine and prone position when performing PCNL. Methods: A systematic electronic search was performed using the database from MEDLINE, Cochrane library and Google Scholar from January 2009 to November 2019. The outcomes assessed were stone free rate, major complication rate, length of hospital stay and mean operation time. Results: A total of 11 articles were included in qualitative and quantitative analysis. The efficacy of PCNL in supine position as determined by stone free rate is significantly lower than in prone position (OR: 0.74; 95% CI: 0.66 – 0.83; p<0.00001), However, major complication rate is also lower in the supine group compared with the prone group (OR: 0.70; 95% CI: 0.51 – 0.96; p=0.03). There is no statistically significant difference in the length of hospital stay and mean operation time between both groups. Conclusion: Prone position leads to a higher stone free rate, but also a higher rate of major complication. Thus, the decision of using which position during PCNL should be based on the surgeon’s experience and clinical aspects of the patients.

<b><i>Objective:</i></b> This study aimed to evaluate the efficacy of our counter-irrigation technique versus the standard technique in percutaneous nephrolithotomy (PCNL) by assessment of the stone-free rate after the procedures and its safety in terms of comparing the intraoperative time, Hb deficit, blood transfusion, length of hospital stay, auxiliary procedures, and perioperative complications with that of the standard one. <b><i>Methods:</i></b> This prospective randomized trial was conducted on patients with renal stone 2–3 cm in diameter without contraindications to PCNL. The patients were randomized into group A in which the counter-irrigation technique has been performed and group B who were managed by the standard technique. The preoperative characteristics including demographic data and stone parameters were compared between both groups. The primary outcome was the stone-free rate assessed by noncontrast spiral CT after 3 months. The secondary outcome included intraoperative time, Hb deficit, blood transfusion, hospital stay, auxiliary procedure required, and rate of complications. <b><i>Results:</i></b> Forty-eight patients were included in this study. Overall, no significant difference was observed between both groups regarding preoperative characteristics, Hb deficit, and complication rate. Operative time was significantly shorter in group B (<i>p</i> = 0.001). None of our patients required blood transfusion. The stone-free rates at 3 months were significantly better in group A (95% for group A and 70% for group B, <i>p</i> = 0.04). <b><i>Conclusions:</i></b> Our results indicate that our counter-irrigation technique has lower stone migration with subsequent significantly better stone-free rate versus the standard technique. We can recommend this technique as a potentially valid option for cases with large stone burden when the access to the upper calyx is feasible to minimize significant residual fragments.

Purpose: To evaluate the safety of one-day length of hospital stay (LOS) after pediatric percutaneous nephrolithotomy (PNL), and to study the predictors of LOS. Methods: A retrospective study included pediatric patients who PNL for renal calculi more than 1 cm between January 2016 and October 2019. PNL was performed in prone position. The nephrostomy tubes and ureteric catheters were removed on the second day and patients were discharged if there was no perforation or significant residual stones. The stone free rate, LOS and the surgical complications were reported. Bivariate and multivariate analysis were used to predict the LOS. Results: 220 patients were identified. The median age (range) was eight (Range: 3–17) years. Stone free rate was achieved in 200 patients (91%) of patients, while residual fragments were detected in 20 patients (9%). Complications, they were reported in 50 (22.7%) patients. 184 (83.6%) of patients stayed at the hospital for only 1 day, while 36 (16. 4%) stayed more than 1 day. Of 36 patients who stayed more than one-day, 34 had complications ( p value <0.001). On multivariate analysis, surgical complications was found to be the only predictor of longer LOS ( p value <0.001). Conclusion: Early nephrostomy tube removal and 1-day length of hospital stay could be a safe option after pediatric PNL. Surgical complications is a statistically significant predictor of longer LOS.

<b><i>Objectives:</i></b> The aim of this study was to provide a randomized controlled trial comparing the outcomes of different access sizes used in the solo ultrasonic-guided minimally invasive percutaneous nephrolithotomy (mini-PCNL). <b><i>Methods:</i></b> From January 2018 to December 2019, a total of 160 cases with single renal stones of &#x3c;25 mm were randomized to undergo mini-PCNLs with Fr16, Fr18, Fr20, or Fr22 accesses. All accesses were established with the axis of the target calyx as the marker for puncture location and then expanded to the desired size. Hemoglobin reduction, operative time, stone-free rate, complications, etc., were all recorded and assessed. <b><i>Results:</i></b> The demographic data were similar, and there were no significantly intergroup differences in stone-free rate, complications, and hospital stay time. The hemoglobin reduction was comparable and was 0.9 ± 0.6, 0.9 ± 0.7, 1.0 ± 0.5, and 1.1 ± 0.7 g/dL for the groups Fr16, Fr18, Fr20, and Fr22, respectively. The operative time was 53.4 ± 14.5, 48.5 ± 15.2, 42.8 ± 13.3, and 43.3 ± 13.1 min for the 4 groups, which decreased significantly from group Fr16 to Fr20, but there was no significant difference between Fr20 and Fr22 groups. <b><i>Conclusions:</i></b> The axis of target calyx is a reliable marker for establishment of percutaneous renal access under ultrasonic guidance. The surgical outcomes of different access sizes were comparable, but the operation time was significantly shortened with the increase of size. However, Fr22 was not more efficient than Fr20.

Abstract Objective Compare the outcomes of RIRS and PCNL for the treatment of 1 to 2 cm lower calyceal renal calculi regarding the stone free rate, operative time, fluoroscopy time, hospital stay and complication rate. Materials and Methods Patients with a single lower calyceal stone with an evidence of a CT diameter between 1 and 2 cm were enrolled in this randomized study. Patients were randomized into two groups: group 1: underwent RIRS (20pts); group 2: underwent PCNL (20 pts). Patients were evaluated with KUB and CT after one month. Results Mean fluoroscopy times and Hospital stay were significantly greater in the PCNL group than in RIRS group, In the RIRS group, the stone-free rate was 85% (17/20 patients); this rate increased to 95% after a second intervention. After a single PCNL procedure, 19 of 20 (95%) patients were completely stone free and For complications, there were minimal differences in both procedures, except for hemorrhage three patients who were treated with PCNL need blood transfusion Conclusions PCNL and RIRS are safe and effective methods for medium-sized LP calculi. For selected patients, RIRS may represent an alternative therapy to PCNL, with acceptable efficacy and low morbidity., RIRS compared to PCNL offers the best outcome in terms of radiation exposure and hospital stay.

Objective: To evaluate the effectiveness of the ultrasonic lithotriptor compared to the combined ultrasonic-pneumatic lithotriptor in percutaneous nephrolithotomy (PCNL). Material & Methods: A systematic search was conducted focusing on studies evaluating nephrolithiasis patients who underwent PCNL using pneumatic, ultrasonic, ultrasonic-pneumatic, or laser lithotriptor. The search was conducted in the PUBMED and Science-direct databases from early to September 2020. Results: There were 406 journals in the initial search. On further selection, 3 randomized controlled trials (RCT) were obtained, with a total of 251 patients. The stone-free rate of three studies had low heterogeneity, I2=0% (P=0.34), so a fixed effect statistical model was used. There was no significant difference (P=0.44) between the stone-free rates from the ultrasonic lithotriptor group and the combination with an odds ratio of 1.26 (95% CI = 0.70-2.26). High heterogeneity was obtained with I2=71% (P=0.03) for the mean fragmentation time, so random effect statistical model was used. There was no significant difference (P=0.56) between the mean fragmentation time of the ultrasonic lithotriptor and combination group with a mean difference of -3.69 (95% CI = -16.09-8.71). Conclusion: The ultrasonic lithotriptor did not have a significant difference in stone-free rate, and mean fragmentation time compared to the combined ultrasonic-pneumatic lithotriptor in PCNL. More RCT studies are needed.

ObjectiveTo compare sequential fascial dilation (SFD) versus one-shot dilation (OSD) in the pediatric patients undergoing percutaneous nephrolithotomy.MethodsThe present study is an observational study. The study subjects were divided into two groups. In group 1, renal dilation was done using the SFD and in group 2, renal dilation was done using the OSD. The amount of time exposed to radiation during access to pelvicalyceal system was estimated. Complications, stone free rates, ancillary procedures for residual stones and hospital stay were compared. Modified Clavien-Dindo classification was used for grading the complications.ResultsRadiation exposure and operative time were less in OSD group (95% confidence interval (CI) 3.068 to 14.072, and 2.565 to 12.435, p<0.005). The mean drop of hematocrit was statistically less significant in OSD group (p=0.032). In both groups, complications, stone free rate and hospital stay were statistically insignificant.ConclusionsOSD is feasible in the children with reduced radiation exposure and shorter operative time. The outcome was similar to SFD.

Abstract. The present study aimed to assess the effectiveness and safety of mini-percutaneous nephrolithotomy (mPNL) in comparison with standard percutaneous nephrolithotomy (sPNL) for the treatment of complex nephrolithiasis. Methods. During the period from 2012 to 2020, 1021 patients with solitary (10.0-30.0 mm), staghorn and multiple renal calculi were retrospectively divided into two groups: sPNL (500 patients) and mPNL (521 patients). The groups were compared by the stone-free rate (%, SFR), the duration of the surgery, complications and hospital stay. Results. SPNL and mPNL were highly effective procedures for the treatment of nephrolithiasis. The mPNL group had longer operative times (81.0±15.5 vs 69.1±13.9 min, p<0.001) and higher frequency tubeless/totally tubeless procedures (41.1 vs 6.8%, p<0.001). mPNL showed a higher SFR (96.4 vs 91.8%, р=0.002 in patients with complete staghorn (90.1 vs 77.3%, p<0.05) and multiple kidney stones (89.5 vs 70.8%, p=0.03). Postoperative decrease in hemoglobin was lower in mPNL group 1.1±0.34 vs 2.1±0.26 g/dl (p<0.001). The incidence rate of urinary tract infections and postoperative hospital stay was lower in the mPNL group: 7.3 vs 13.2%, p=0.03 and 1.9±0.6 vs 4.3±2.4 days, р<0.001. Conclusions. MPNL is a safe and effective treatment for patients with complex renal stones with an improved stone-free rate and lower complication rate and shorter hospital stay. Smaller diameter tract in mPNL procedures was associated with a longer duration of surgery.
