RESUMO
The rising prevalence of kidney stone disease is associated with significant costs to healthcare systems worldwide. This is in part due to direct procedural and medical management costs, as well as indirect costs to health systems, patients, and families. A number of manuscripts evaulating the economics of stone disease have been published since the 2008s International Consultation on Stone Disease. These highlight costs associated with stone disease, including acute management, surgical management, and medical management. This work hopes to highlight optimization in care by reducing inefficient treatments and maximizing cost-efficient preventative strategies.

PURPOSE: To evaluate and compare effectivity and safety of flexible ureteroscopy (F-URS) and mini-percutaneous nephrolithotomy (mPNL) for 10-20 mm renal stones in obese patients. METHODS: Between 2012 and 2015, charts of patients who were treated with F-URS or mPNL for 10-20 mm kidney stone(s) were analyzed. Patients with BMI > 30 kg/m(2) were enrolled into the study. Total of 315 patients were treated with mPNL, and 56 patients were matched our inclusion criteria. In the same period, F-URS was performed in 669 patients, and 157 of them had 10-20 mm kidney stones, and their BMI values were >30 kg/m(2). The patients were retrospectively matched at a 1:1 ratio to index F-URS-mPNL cases with respect to the patient age, gender, ASA score, BMI and size, number, and location of stone. RESULTS: Gender, age, BMI, stone size, stone number, location of stone(s), and ASA scores were similar between groups. The mean operation time was significantly longer in mPNL group (p: 0.021). However, the mean fluoroscopy time was similar (p: 0.270). Hemoglobin drop requiring blood transfusion and angioembolization was performed in two and one patients after mPNL, respectively. Overall complication rate was significantly higher in mPNL group than F-URS group (30.3 vs. 5.3 %, p: 0.001). CONCLUSION: Our results demonstrated that both F-URS and mPNL achieve acceptable stone-free rates in obese patients with 10-20 mm renal stones. However, complication rates were significantly lower in F-URS group.

PURPOSE: To identify patient- and procedure-related factors that increase the risk of hospital readmission and emergency room (ER) visits after percutaneous nephrolithotomy (PNL). MATERIALS AND METHODS: We retrospectively reviewed the records of patients with kidney stones treated via PNL in two tertiary referral hospitals between 2008 and 2014. Patient demographics including age, body mass indices, ASA score, stone size, presence of anatomic abnormality and comorbidity, operative and postoperative measures, and ER visit and rehospitalization rates were reviewed. Unplanned readmission to the hospital, including elective, and ER visits due to any reason related to the PNL procedure were primarily examined. The factors affecting ER visit and rehospitalization rate were analyzed using logistic regression analysis. RESULTS: A total of 1024 patients (mean age 46.57 years) were enrolled into the study. Mean stone size was 28.5 mm. Stone-free status was achieved in 81.7 % of the procedures. Complications occurred at a rate of 6.44 % in the postoperative period. ER visit and rehospitalization rates were 5.76 and 5.27 %, respectively. While stone complexity, anatomic abnormalities, and postoperative course were found to be factors affecting ER visit, postoperative course and hospitalization time were main predictors for rehospitalization rate. CONCLUSIONS: Our outcomes demonstrate that patients, who had an anatomic abnormality and complex kidney stone, were more likely to have an unplanned hospital readmission. Patients with a history of perioperative and/or postoperative complication seem to have a tendency to unplanned readmission and rehospitalization.

PURPOSE: To investigate patient- and procedure-related factors associated with hospital re-admission (HR) and re-hospitalization following flexible ureteroscopy (f-URS). PATIENTS AND METHODS: The records of patients who underwent f-URS for renal stones in two reference centers between 2011 and 2015 were examined retrospectively. Patients who were re-admitted to the hospital or re-hospitalized for any reason within 30 days after hospital discharge related to the f-URS procedure were evaluated. The patient- and procedure-related factors affecting the re-admission and re-hospitalization rates were revealed using backward stepwise multiple binary logistic regression analysis. RESULTS: The study included 647 patients with a mean age of 46.1 ± 13.7 years. The mean BMI was 27.3 ± 4.6 kg/m(2), and the median ASA score was 1.85. The mean stone diameter was 14.2 ± 5.3 mm. The mean operation and fluoroscopy times were 50.2 ± 16.9 min and 43.1 ± 37.6 s, respectively. The mean hospitalization time was 1.42 ± 0.84 days, and the complication rate was 12.8 % (83/647). Overall, 523 (80.3 %) patients became stone-free, while residual fragments <4 mm were detected in 73 (11.3 %) patients. The procedure failed in 7.9 % of the cases. While 82 (12.7 %) patients were re-admitted, 31 (4.8 %) patients were re-hospitalized for further treatment. Stone-free status was an independent predictor of HR, while the stone-free status, hospitalization time, and postoperative complications all predicted re-hospitalization. CONCLUSIONS: We found that inability to achieve stone-free status predicted HR and re-hospitalization, while postoperative complication and prolonged hospitalization also predicted re-hospitalization.

PURPOSE: To present a retrospective comparative clinical study of micropercutaneous nephrolithotomy (microperc) versus flexible ureterorenoscopy (F-URS) in treatment of moderate-size lower-pole stones (LPSs). METHODS: We retrospectively reviewed data on patients with isolated LPSs ≤2 cm in diameter treated with F-URS and/or microperc in two referral centers. Patients were divided into two groups by treatment modality: F-URS (Group 1) and microperc (Group 2). Demographics and perioperative parameters were analyzed. RESULTS: A total of 127 patients with isolated LPSs were treated via F-URS (Group 1, n = 59) and microperc (Group 2, n = 68). Mean patient age in microperc group was slightly lower than in F-URS group (p = 0.112). We found no statistically significant difference in terms of either the size or number of stones in two groups (p = 0.113 and p = 0.209, respectively). Operative time was shorter in microperc, whereas fluoroscopy time was shorter in F-URS (60.1 ± 26.2 vs. 46.2 ± 24.3 min, p < 0.001; and 28.3 ± 19.1 vs. 108.9 ± 65.2 s, p < 0.001). Mean fall in hemoglobin level was statistically significantly lower in F-URS and hospitalization time was also significantly shorter in F-URS (0.68 ± 0.51 vs. 1.29 ± 0.88 mg/dL, p < 0.001; and 23.0 ± 58.1 vs. 33.8 ± 17.2 h, p < 0.001, respectively). Stone-free rates (SFRs) were 74.5 % (44/59) in Group 1 and 88.2 % (60/68) in Group 2 (p < 0.001). CONCLUSIONS: We found that microperc was safe and efficacious when used to treat moderate-size LPSs and may be considered as an alternative to F-URS, affording a higher SFR. Our study supports the notion that microperc should play an increasing role in treatment of LPSs.

OBJECTIVE: The objective is to compare the analgesic effects of diclofenac, acetaminophen, and acupuncture in urolithiasis-driven renal colic pain relief. METHODS: Renal colic patients were divided randomly into 3 groups. Patients in group I (n = 40) were treated with intravenous acetaminophen, those in group II (n = 41) with acupuncture, and those in group III (n = 40) with a 75-mg intramuscular injection diclofenac sodium. Visual analogue scale (VAS) and verbal rating scale (VRS) were used to assess pain intensity after 10, 30, 60, and 120 minutes. RESULTS: No significant differences in baseline VAS or VRS were found with regard to age or sex. After 10 minutes, all 3 groups experienced a significant decrease in VAS and VRS scores, with the most drastic decrease occurring in group II. After 30 minutes, there was a significantly higher decrease in group III than in group I (P = .001). After 60 minutes, mean VAS scores of groups I and III (P = .753) were similar. The mean VAS score of group III was lower than that of group II (P = .013). After 120 minutes, the difference in the VAS scores was (P = .000) between groups I and II and between groups II and III. Yet, the VAS evaluation made after 120 minutes revealed statistically similar outcomes for groups I and III (P = .488). The statistical findings for VRS evaluations made after 10, 30, 60, and 120 were similar to those for VAS. CONCLUSIONS: In renal colic patients with a possible nonsteroidal anti-inflammatory drug and acetaminophen side effect risk, acupuncture emerges as an alternative treatment modality.

PURPOSE: We assessed and evaluated attitudes and knowledge regarding ionizing radiation of urology surgery room staff. MATERIALS AND METHODS: A questionnaire was sent by e-mail to urology surgery room personnel in Turkey, between June and August 2013. The questionnaire included demographic questions and questions regarding radiation exposure and protection. RESULTS: In total, 127 questionnaires were answered. Of them, 62 (48.8%) were nurses, 51 (40.2%) were other personnel, and 14 (11%) were radiological technicians. In total, 113 (89%) participants had some knowledge of radiation, but only 56 (44.1%) had received specific education or training regarding the harmful effects of radiation. In total, 92 (72.4%) participants indicated that they used a lead apron and a thyroid shield. In the subgroup that had received education about the harmful effects of radiation, the use ratio for all protective procedures was 21.4% (n=12); this ratio was only 2.8% (n=2) for those with no specific training; the difference was statistically significant (p=0.004). Regarding dosimeters, the use rates were 100% for radiology technicians, 46.8% for nurses, and 31.4% for other hospital personnel; these differences were statistically significant (p<0.001). No significant relationship between working period in the surgery room, number of daily fluoroscopy procedures, education, task, and use of radiation protection measures was found. CONCLUSIONS: It is clear that operating room-allied health personnel exposed to radiation do not have sufficient knowledge of ionizing radiation and they do not take sufficient protective measures.

OBJECTIVES: To review our experience with ureteroscopy (URS) in the treatment of ureteral calculi and stratify intraoperative complications of URS according to the modified Satava classification system. PATIENTS AND METHODS: We performed a retrospective analysis of 1,208 patients (672 males and 536 females), with a mean age of 43.1 years (range 1-78), who underwent ureteroscopic procedures for removal of ureteral stones. Intraoperative complications were recorded according to modified Satava classification system. Grade 1 complications included incidents without consequences for the patient; grade 2 complications, which are treated intraoperatively with endoscopic surgery (grade 2a) or required endoscopic re-treatment (grade 2b); and grade 3 complications included incidents requiring open or laparoscopic surgery. RESULTS: The stones were completely removed in 1,067 (88.3%) patients after primary procedure by either simple extraction or after fragmentation. The overall incidence of intraoperative complications was 12.6%. The most common complications were proximal stone migration (3.9%), mucosal injury (2.8%), bleeding (1.9%), inability to reach stone (1.8%), malfunctioning or breakage of instruments (0.8%), ureteral perforation (0.8%) and ureteral avulsion (0.16%). According to modified Satava classification system, there were 4.5% grade 1; 4.4% grade 2a; 3.2% grade 2b; and 0.57% grade 3 complications. CONCLUSION: We think that modified Satava classification is a quick and simple system for describing the severity of intraoperative URS complications and this grading system will facilitate a better comparison for the surgical outcomes obtained from different centers.

INTRODUCTION AND HYPOTHESIS: We present our minimum 1-year results with a mesh spiral-sling procedure (MSSP) for managing refractory and disabling stress urinary incontinence (SUI) in women. METHODS: Thirty-four women were treated with MSSP between 2007 and 2011. Six had incomplete data and were excluded from analysis. Study cohort comprised 21 women with refractory (mean number of previous surgeries 2.2; range 1-6) and seen with primary disabling SUI. All patients had marked intrinsic sphincter deficiency (ISD) with a Valsalva leak-point pressure (VLPP) <60 cm H2O. Preoperative workup included assessing the impact of voiding symptoms using the International Consultation on Incontinence Questionnaire--Short Form (ICIQ-SF), estimating the daily number of pads, and urodynamic studies. Preoperative and postoperative findings were compared using the Wilcoxon signed-rank test. RESULTS: Intraoperative unilateral bladder-neck perforation occurred in two women during dorsal urethrolysis. With a mean follow-up of 26 months (range 12-48), SUI was cured in 71.4% of patients. Distal urethral reconstruction with vaginal mucosal flaps was performed in two patients with short urethral length (<2.5 cm) due to recurrence of SUI 10 months after MSSP. Mean ICIQ-SF score decreased from 19.4 ± 3.6 preoperatively to 7.3 ± 2.8 postoperatively (p = 0.001). Mean daily pad number decreased from 5.2 preoperatively to 1.2 postoperatively (p = 0.02). Urethral or vaginal erosion was not observed in any case during follow-up. CONCLUSION: Using spiral slings may be a viable option in managing refractory and disabling SUI.

PURPOSE: We conducted a multicenter pediatric study of ureteral stents unintentionally left in situ. MATERIALS AND METHODS: A total of 22 patients with encrusted Double-J® ureteral stents unintentionally left in situ were treated at 4 centers between January 2007 and March 2012. Stone burdens were estimated using plain radiography and computerized tomography. Treatment decision was made based on clinical and radiological findings or stone burden. RESULTS: Nine girls and 13 boys with a mean age of 9.5 years (range 2 to 16) were analyzed. Mean indwelling time of ureteral stent was 21.7 months (range 6 to 60). Stents were inserted for the indication of urolithiasis (17 patients) and reconstructive urological intervention (5). In 2 patients stents had been placed bilaterally. Mean stent stone burden was 184 mm(2) on plain radiography and 247 mm(2) on computerized tomography, a difference that was statistically significant (p = 0.002). Shock wave lithotripsy was done in 6 cases. Endoscopic procedures were performed in all patients, including ureteroscopy in 8, simple stent removal in 7, endoscopic cystolithotripsy in 6, percutaneous nephrolithotomy in 5, retrograde intrarenal surgery in 3 and percutaneous cystolithotripsy in 2. Surgical removal of each stent required a mean of 1.5 interventions and a mean hospital stay of 4.4 days. CONCLUSIONS: At experienced centers combined endourological techniques can achieve successful and safe management of forgotten stents even in the pediatric age group. Thus, routine preprocedural tomography is a must in children with forgotten ureteral stents.

OBJECTIVE: To evaluate the outcomes of bipolar vs conventional monopolar transurethral resection of the prostate (TURP) on urinary and erectile function. MATERIAL AND METHODS: A total of 286 patients with benign prostatic hyperplasia (BPH) were randomized to bipolar or monopolar conventional TURP treatment groups. Operative and early postoperative variables and complications were recorded and all patients were re-evaluated at 1, 3, 6 and 12 months after surgery using the International Prostate Symptom Score (IPSS), uroflowmetry, post-void residual urine volume (PVR) and the erectile function domain of the International Index of Erectile Function (IIEF-ED). A comparative evaluation of erectile function was performed on 188 preoperatively non-catheterized patients with regular sexual partners. RESULTS: The operating time was shorter in the bipolar TURP group. Postoperative bleeding and blood transfusion requirements did not significantly differ between the two groups. Sodium levels were significantly lower in the monopolar group than in the bipolar group. Transuretheral resection syndrome developed in two (1.4%) patients in the monopolar group. Both groups had similar and significantly improved IPSS values, maximum urinary flow rate values and PVR measurement. ED worsened in 32 (17.0%) patients, improved in 53 (28.2%) patients, and was unchanged in 103 (54.8%) patients. Changes in the IIEF scores during the follow-up period were similar between the bipolar and monopolar groups. CONCLUSION: Bipolar TURP is a safe and effective procedure that is associated with a significantly shorter operating time, a smaller reduction in serum sodium levels and a similar efficacy compared with conventional monopolar TURP.

OBJECTIVES: To compare the outcomes of shock wave lithotripsy (SWL), percutaneous nephrolithotomy (PNL), and retrograde intrarenal surgery (RIRS) for 10-20 mm radiolucent renal calculi by evaluating stone-free rates and associated complications. PATIENTS AND METHODS: A total of 437 patients at 7 institutions who underwent SWL (n = 251), PNL (n = 140), or RIRS (n = 46) were enrolled in our study. Clinical success was defined as stone-free status or asymptomatic insignificant residual fragments <3 mm. The success rates, auxiliary procedures, and complications were compared in each group. RESULTS: Success rates were 66.5, 91.4, and 87% for SWL, PNL, and RIRS (p < 0.001). The need for auxiliary procedures was more common after SWL than PNL and RIRS (21.9 vs 5.7 vs 8.7%, respectively; p < 0.001). The overall complication rates for the SWL, PNL, and RIRS were 7.6, 22.1, and 10.9%, respectively (p < 0.001). Thirteen patients in PNL group received blood transfusions, while none of the patients in RIRS and SWL groups transfused. Hospitalization time per patient was 1.3 ± 0.5 days in the RIRS group, while it was 2.6 ± 0.9 days in the PNL group (p < 0.001). Fluoroscopy and operation time were significantly longer in the PNL group compared to RIRS (145.7 ± 101.7 vs 28.7 ± 18.7 s, and 57.5 ± 22.1 vs 43.1 ± 17 min, respectively). CONCLUSIONS: For treatment of moderate-sized radiolucent renal stones, RIRS and PNL provide significantly higher success and lower retreatment rate compared with SWL. Although PNL is effective, its biggest drawback is its invasiveness. Blood loss, radiation exposure, hospital stay, and morbidities of PNL can be significantly reduced with RIRS technique.

OBJECTIVE: To evaluate whether renal parenchymal thickness (RPT) has an effect on the outcomes of percutaneous nephrolithotomy (PNL). METHODS: We performed a retrospective analysis of 144 patients with lower pole and/or renal pelvic stones who underwent PNL. The relationship between RPT and peri- and postoperative measures was evaluated. RESULTS: The average age was 45.94 ± 14.47 (15-76) years. The mean BMI was calculated as 27.47 ± 4.73 (16.9-44.9) kg/m(2). The mean stone burden was 293 ± 126 (150-800 mm(2)). The mean RPT was measured as 17.33 ± 5.32 (6-35) mm. No correlation was detected between the RPT and the operation or fluoroscopy times or the duration of hospitalization (p = 0.63, 0.52, 0.08, respectively). The mean drop in hemoglobin level was 1.45 ± 1.25 (0-9) g/dl. A negative correlation was detected between hemoglobin drop and RPT (p = 0.01, r = -0.23). However, the RPT was similar in patients who did or did not require a blood transfusion (p = 0.09). The RPT was found to have no impact on success rate (p = 0.4). CONCLUSION: The postoperative hemoglobin drop increases in parallel with the increase in RPT. However, no relationship was detected between the RPT and blood transfusion, overall success rate or any other perioperative parameters.

OBJECTIVES: It was the aim of this study to evaluate and compare the outcomes of percutaneous nephrolithotomy (PNL) for the treatment of posterior and anterior caliceal stones. PATIENTS AND METHODS: We performed a retrospective analysis of 86 patients with isolated caliceal stones who underwent PNL between 2011 and 2012. The patients were classified into two groups according to the localization of the stone, either in the anterior (group 1, n = 41) or posterior (group 2, n = 45) calyx, on axial plane computed tomography. RESULTS: The mean age, male/female ratio and stone size and location were similar in both groups. Fluoroscopy, operation time and duration of hospitalization were also similar between groups. Patients in group 1 had a greater postoperative hemoglobin drop than patients in group 2. Blood transfusion was required for 5 patients in group 1 and for 4 patients in group 2. In addition, open conversion was required for 2 patients in group 1 during the early postoperative period because of extensive bleeding. Hemodynamics were stabilized with angioembolization in 2 patients with prolonged hematuria in group 1. The overall success and complication rates were similar in both groups. CONCLUSION: Although the postoperative hemoglobin drop did not significantly differ between groups, hemorrhaging was more severe in patients with anterior caliceal stones than in those with posterior caliceal stones.

PURPOSE: "Snodgraft" modification has been proposed to reduce the risk of meatal/neourethral stenosis in distal hypospadias. We applied the Snodgraft technique by using inner preputial graft in primary distal hypospadias repair. MATERIALS AND METHODS: A total of 102 consecutive patients undergoing the Snodgraft procedure were prospectively studied between 2006 and 2011. Mean patient age was 7.2 years. Localization of the meatus was glanular in 5 patients, coronal in 49, subcoronal in 45 and mid penile in 3. In all patients the posterior urethral plate was incised, and the graft harvested from the inner prepuce was sutured from the old meatus to the tip of the glans. A neourethra was created over a urethral catheter using 6-zero polyglactin suture. An interpositional flap was laid over the urethra as a second barrier. All patients were followed at 3 to 6-month intervals for cosmetic and functional results. RESULTS: At a mean of 2.4 years of followup no patient had meatal stenosis or diverticulum at the inlay graft site. However, urethrocutaneous fistula was observed in 10 patients (9.8%). A slit-like appearance of neomeatus was achieved in all patients. During followup no obstructive urinary flow pattern was detected, and early and long-term maximum urine flow rates were comparable. CONCLUSIONS: No meatal/neourethral stenosis was observed in any patient undergoing a Snodgraft procedure. A randomized trial will be needed to prove that the incidence of meatal/neourethral stenosis is lower after Snodgraft repair compared to routine tubularized incised plate repair.

UNLABELLED: Study Type--Prognosis (cohort) Level of Evidence 2b. What's known on the subject? and What does the study add? The presence of metabolic syndrome is associated with development of kidney stones and an increase in the stone-recurrence rate. However, studies reporting long-term results of percutaneous nephrolithotomy (PCNL) in metabolic syndrome are lacking. The present study showed that metabolic syndrome was associated with worsening renal function at long-term follow-up and the stone-recurrence rate recurrence after PCNL in patients with metabolic syndrome was 3.2-fold higher compared with the control group. OBJECTIVE: ⢠To investigate the impact of metabolic syndrome on long-term kidney function and stone recurrence rates after percutaneous nephrolithotomy (PCNL). PATIENTS AND METHODS: ⢠In all, 73 patients with metabolic syndrome who underwent stone analysis and had a minimum follow-up of 12 months after PCNL were reviewed. ⢠In addition, 73 patients without any metabolic syndrome components who had undergone PCNL and were followed-up for at least 12 months were included in the study as the control group. ⢠These control group patients were selected from 226 patients who were matched with the patients with metabolic syndrome using a 1 : 1 ratio. The matching parameters were age, gender and stone size. RESULTS: ⢠Stone analyses showed that calcium oxalate monohydrate (52.0%) and uric acid (21.9%) were most common among patients with metabolic syndrome, whereas calcium oxalate monohydrate (76.7%) was the most common stone type in the control group. ⢠Stone recurrences occurred with a mean (sd, range) of 36.1 (21.3, 12-109) months follow-up in 26 patients (41.9%) and 12 patients (18.9%) in the metabolic syndrome and control groups, respectively (P = 0.003). ⢠While estimated glomerular filtration rate was decreased from 87.8 to 66.6 mL/min/1.73 m(2) in the metabolic syndrome group, it changed from 96.4 to 91.2 mL/min/1.73 m(2) in control group at long-term follow-up. CONCLUSIONS: ⢠The most frequent stone type was calcium oxalate monohydrate in patients with or without metabolic syndrome. ⢠In patients with metabolic syndrome who underwent PCNL, the stone recurrence rate was >40%. ⢠Metabolic syndrome is associated with worsening renal function at long-term follow-up.

The objective of this study was to describe and present the initial results of a computer-based system that tracks ureteral stents and automatically sends a reminder through a short message service (SMS) to both the patient's and the urologist's mobile phones Using an integrated stent register program (SRP) and a stent extraction reminder program (SERP) with an electronic patient record program (EPRP) located within our hospital's computer network. In this system, the demographic data of all of the patients are recorded into the password-protected EPRP. After a stent is inserted, the surgeon enters the details of the operation into the EPRP. The SRP automatically asks the user to define the "optimal stent life (OSL)". The SERP checks the recorded patients daily and sends an SMS reminder to staff and patient when the OSL is reached. The SERP continues to send reminders via the SMS until stent is removed. We analyzed the success of the SMS recall system. A total of 186 patients received stents over an 11-month period. The patients in group-2 (n = 108) were recalled by the SERP, and the remainder of the patients (n = 78, group-1) were not included in the project. The mean delay from the designated OSL to the time of stent removal was 307 ± 118.6 (72-1,344) and 14.6 ± 2.06 (5-36) h in groups 1 and 2, respectively (p < 0.0001). Our initial results showed that the SRP and SERP prevent stent removal from being forgotten, thus preventing related medical and legal problems.

Laparoscopic nephrectomy has become the gold standard procedure for nonfunctioning or symptomatic benign kidneys due to renal calculi, obstructive, refluxive, and inflammatory nephropathies or renovascular hypertension. We aimed to investigate the effect of renal calculi as a reason of non-functioning on the progress and complication rates of the retroperitoneoscopic nephrectomy (RPN). During a 2-year period, 108 patients with benign renal conditions underwent RPN by single surgeon. Among these patients, total of 27 (Group 1) with a non-functioning kidney due to renal calculi were retrospectively compared with 27 patients (Group 2) with other benign renal conditions. The two groups were matched for age, body mass index, and previous renal surgery. We analyzed operative and post-operative findings and complications. The mean age and the BMI of the groups were similar. The operation time was significantly longer in Group 1 than Group 2 (p = 0.0001). There was no significant difference between the groups with respect to mean hemoglobin drop postoperatively (p = 0.9) and hospitalization time (p = 0.06). The perioperative and postoperative complication rates were higher in Group 1 but not statistically different from Group 2 (p = 0.19, p = 0.29, respectively). RPN for nonfunctioning calculous kidneys is more challenging procedure and is associated with prolonged operation time related to difficult dissection of dense adhesions. It can be safely performed by experienced hands with similar perioperative and postoperative complication rates as well as for other benign conditions of the kidney.

The aim of the study is to investigate whether laparoscopic pyelolithotomy (LPL) could find a place in the management of large renal pelvic stones which are generally considered as excellent indications for percutaneous nephrolithotomy (PNL). Between 2006 and 2009, 26 consecutive patients with large (>4 cm(2)) renal pelvic stones were treated by LPL and their charts were compared to 26 match-paired patients treated with PNL during the same period. The patients were matched for age, BMI, stone size and location as well as presence of congenital anomalies. Perioperative and postoperative findings were compared. The mean age, mean stone size, rate of congenital anomalies, history open renal surgery and shock wave lithotripsy were similar in both groups (p > 0.05). The mean operation time was 138.40 ± 51.19 (range 70-240) min in LPL group as compared to 57.92 ± 21.12 (range 40-110) min in PNL group (p < 0.0001). There was one (3.8%) open conversion in the LPL group due to dense perirenal adhesions making the dissection difficult. The ureteropelvic junction (UPJ) obstruction concomitant to pelvic stones was successfully repaired laparoscopically in two cases. The mean drop in postoperative hemoglobin level was 0.9 ± 0.6 (range 0-2) g/dl in LPL group and 1.7 ± 1.1 (range 0-4) g/dl in PNL group (p = 0.024). Hospitalization was significantly shorter in PNL than LPL group (p = 0.0001). Stone-free rates were similar. Laparoscopic pyelolithotomy is associated with a longer operation time, is more invasive, and requires more skills when compared to PNL. However, LPL is associated with less blood loss. Laparoscopic pyelolithotomy is indicated for congenitally anomalous kidneys and especially in patients with concomitant UPJ.

Lichen sclerosus (LS) is a chronic, inflammatory condition which commonly involves the anogenital skin. This condition may affect the foreskin, glans, frenulum, meatus and urethra in males. It manifests itself with voiding symptoms. Obstructive uropathy is an extremely rare clinical presentation in childhood. This study reports the case of a 13-year-old boy presenting with obstructive uropathy due to LS and reviews the published data on the diagnosis, management and follow-up of this condition.
