Abstract
INTRODUCTION AND OBJECTIVES We aimed to point out the ureteral access facility and obstruction removal efficiency of mini-URS in the use of proximal ureteral stone management in children under five-year-old. PATIENTS We retrospectively reviewed the data of 26 children who underwent mini-URS-LL for obstructive stones in proximal ureter between January 2016 and August 2018. The effectiveness of the mini-URS-LL was assessed based on the feasibility, reliability, and success of the technique. RESULTS Mean age was 3 ± 1.3 years, and 11 (42.3%) patients were ≤2 years old, remaining 15 (57.7%) were aged 3-5 years. Mean stone size was 9.11 ± 3.02 mm. A stone-free status was obtained at the end of 31 ureteroscopic procedure in 24 (92.3%) patients. The mean age was found significantly higher in patients who had the procedure without pre-stenting than the others who did (P = .027). No perioperative complication was experienced. CONCLUSION In preschool-age children, laser lithotripsy with mini-URS may be a safe technique in the hands with advanced endo-urological skills but it has low efficacy with higher rates of prestenting causing additional anesthesia sessions.

Abstract
Purpose: Cystinuria is a genetic disorder characterized by a defective reabsorption of cystine and dibasic amino acids leading to development of urinary tract calculi from childhood onward. Cystine lithiasis is known to be resistant to fragmentation. The aim was to evaluate our long-term experience with extracorporeal shockwave lithotripsy (ESWL) used as first-line urological treatment to treat cystine stones in children. Methods: We retrospectively reviewed the charts of all children who underwent ESWL for cystine stone. We assessed the 3-month stone-free rate, according to age, younger (group 1) or older (group 2) than 2 years old. Results: Between 2003 and 2016, 15 patients with a median (IQR) age at first treatment of 48 (15-108) months underwent ESWL in monotherapy. Median age was, respectively, 15 and 108 months in each group. The median (IQR) stone burden was 2,620 (1,202-8,265) mm3 in group I and 4,588 (2,039-5,427) mm3 in group II (p = 0.96). Eleven patients had bilateral calculi. ESWL was repeated on average 2.4 times, with a maximum of 4 for patients of group I, and 4.8 times, with a maximum of 9 for group II (p > 0.05). ESWL in monotherapy was significantly more efficient to reach stone-free status for children under 2 years of age: 83% vs. 6.2% (p = 0.040). The median (IQR) follow-up of the study was 69 (42-111) months. Conclusion: ESWL appears as a valid urological option for the treatment of cystine stones, in young children. Even if cystine stones are known to be resistant to fragmentation, we report 83% of stone-free status at 3 months with ESWL used in monotherapy in children under 2 years old with cystinuria. In older children, the success rate is too low to recommend ESWL as a first line approach.

Cost-Effectiveness Analysis of the Management of Distal Ureteral Stones in Children. Urology 2019; 127:107-112. [PMID: 30790649 DOI: 10.1016/j.urology.2019.02.007] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.6] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/04/2018] [Revised: 01/29/2019] [Accepted: 02/08/2019] [Indexed: 11/23/2022]
Abstract
OBJECTIVE To determine the most cost-effective approach to the management of distal ureteral stones in children given the potential for recurrent renal colic during a trial of passage versus potential stent discomfort and complications of ureteroscopy. METHODS We developed a decision tree to project costs and clinical outcomes associated with observation, medical explusive therapy (MET), and ureteroscopy for the management of an index patient with a 4-mm-distal ureteral stone. We determined which strategy would be least costly and offer the most pain-free days within 30days of diagnosis. We performed a one-way sensitivity analysis on the probability of successful stone passage with MET. We obtained probabilities from the literature and costs from the 2016 Pediatric Health Information System Database. RESULTS Ureteroscopy was the costliest strategy but maximized the number of pain-free days within 30days of diagnosis ($5282/29 pain-free days). MET was less costly than ureteroscopy but also less effective ($615/21.8 pain-free days). Observation cost more than MET and was also less effective ($2139/15.5 pain-free days). The one-way sensitivity analysis on the probability of successful stone passage with MET demonstrated that ureteroscopy always has the highest net monetary benefits value and is therefore the recommended strategy given a fixed willingness-to-pay. DISCUSSION Using a rigorous decision-science approach, we found that ureteroscopy is the recommended strategy in children with small distal ureteral stones. Although it costs more than MET, it resulted in more pain-free days in the first 30days following diagnosis given the faster resolution of the stone episode.

Abstract
Objectives To compare the 7.5–9.5F ureteroscope (URS) with the 4.5–6.5F URS (Ultra-Thin) in terms of success and complication rates in adult patients with ureteric and renal pelvic stones. Patients and methods In all, 41 patients treated with 7.5–9.5F semi-rigid URS (Group 1) and 33 patients treated with the Ultra-Thin (Group 2) were prospectively included in the study. All patients underwent holmium laser ureteroscopic lithotripsy. In each group, when the selected ureteroscopic intervention failed to reach or disintegrate the stone, the URS was replaced with the other one. Outcome criteria were: success and complication rates, stone size and stone surface area, operative time, laser time, usage of guidewire, and postoperative JJ-catheter placement. Results The ureteroscopic lithotripsy in 36 of 41 (87.8%) and 24 of 33 (72.7%) patients was completed without a need to replace the URS with the other one in groups 1 and 2, respectively (P = 0.67). After replacement of the 7.5–9.5F URS with the Ultra-Thin for patients who failed in Group 1, the overall stone-free rate (SFR) improved to 97.5% (P = 0.014). In Group 2, after replacement of the Ultra-Thin with the 7.5–9.5F URS for the failed patients, the overall SFR improved to 96.9% (P = 0.02). There was no significant difference between the groups for complications. Postoperative JJ stenting was significantly less in Group 2 (21.2%) in comparison to Group 1 (46.3%) (P = 0.02). Conclusions The Ultra-Thin has a similar success rate as the 7.5–9.5F URS in the treatment of ureteric stones and is a feasible option in patients in whom a conventional URS cannot be advanced through any segment of the ureter.

Abstract
Background: Treatment of upper urinary tract stones measuring >2 cm in children aged <3 years is challenging. Although adult-sized instruments are usually available, in pediatric populations such instruments seem unreasonable and unfit for children with small kidneys and narrow ureters. We use ultra-miniaturized endoscopes and instruments to reduce the damage to normal tissues in pediatric patients. Case Presentation: We treated a 2-year-old boy with >2-cm bilateral cystine kidney stones. We decided to perform retrograde intrarenal surgery using an ultrathin (4.5F) semi-rigid ureteroscope for the right kidney stone (2.0 × 1.2 cm) in the lithotomy position and super ultra-minimally invasive endoscopy combined with intrarenal surgery with a percutaneous 8.5F to 9.5F tract sheath for the left kidney stone (3.5 × 2.4 cm) under the Barts modified Valdivia position. These procedures were successful for the bilateral kidney stones. Postoperatively, the patient was stone-free without major complications. Conclusion: We believe that ultra-minimally invasive endoscopic intrarenal surgery is safe and efficient in pediatric patients. Furthermore, the Barts modified Valdivia position was safely utilized in our 2-year-old patient with multiple large kidney stones.

Experience of retaining encrusted ureteral stents: URL by 4.5/6.5F ureteroscope can reduce the possibility of PCNL. Urolithiasis 2017; 46:357-361.

Abstract
The purpose of the study was to present our experience of retaining encrusted ureteral stents (EUS) and discuss the effectiveness of 4.5/6.5F ureteroscope (URS) in the procedure. The data of patients with EUS in our center from January 2012 to December 2016 were retrospectively analyzed. The inclusion criterion was ureteral stents that required intervention above the ureteral orifice to retain and was proved to be encrusted. Impacted stents would be removed by ureteroscope lithotripsy (URL) via 8/9.8F or 4.5/6.5F URS. Percutaneous nephrolithotomy (PCNL) then be the further step if URL failed. 46 cases of EUS were treated in 36 patients from January 2012 to December 2016 in our institution. All subjects consisted of 18 males and 18 females; the average age was 49.81 ± 16.40 years (range 5-86). The mean time from stent insertion to encrustation was 9.28 ± 17.15 months (range 1-120). URL was performed in 44 cases (95.7%), including 19 cases (41.3%) by 8/9.8F URS and 25 cases (54.4%) by 4.5/6.5F URS due to the conventional URS's failure to get into ureteral orifice or further part of ureter. Two patients (4.3%) underwent PCNL due to the inseparable circle developed by the intra-renal segment of encrusted stents. None of the patients underwent extracorporeal shock wave lithotripsy (ESWL) and open surgery. All stents were eventually removed without blood transfusion or ureteral injury, except three cases with post-operative fever. All procedures were performed under one-session anesthesia. URL by 4.5/6.5F ureteroscope might increase the success rate of retaining encrusted ureteral stents remarkably, and then reduce the possibility of PCNL effectively.

Abstract
Objective To describe our experience and results of using the MicroPerc™ micropercutaneous nephrolithotomy armamentarium (PolyDiagnost, Germany) for unusual indications unexplored using this modality. Patients and methods We used the MicroPerc™ system for stone clearance in three ureteric calculi, two bladder calculi, one case of urethral calculus, for antegrade biopsy in a case of upper tract urothelial carcinoma, for Deflux® (dextranomer/hyaluronic copolymer, Salix Pharmaceuticals, Uppsala, Sweden) injection in three cases of vesico-ureteric reflux (VUR), and three cases of posterior urethral valve (PUV) fulgurations. A 4.85-F ‘All-Seeing Needle®’ (PolyDiagnost) was used in most of the cases. An 8-F mini-micro sheath was used where stability was deemed necessary. Clinical data were collected in a dedicated database. Intraoperative variables, postoperative complications, and outcomes were assessed. Results All patients were successfully treated with complete stone clearance at 1 month with no residual fragments. The antegrade biopsy confirmed a high-grade papillary neoplasm. There were no technical difficulties with injection of Deflux or PUV fulgurations. Follow-up at 1 year revealed no stone recurrence, resolved reflux in all three cases, and all the children that had had PUVs were voiding well. The small sample and retrospective nature of the analysis are the limitations of this study. Conclusion MicroPerc™, besides its usual use for minimally invasive percutaneous nephrolithotomy, can also be feasibly used for ureteric, bladder and urethral stones, and for treating non-calculus diseases such as PUVs and VUR. True to its name, it may be an ‘All-Seeing Needle’ in reality with much more to offer and harvest from.

Abstract
OBJECTIVE The objective of this study was to demonstrate the efficacy and safety of micro-ureteroscopy (micro-URS) in the management of distal ureteral stones in the pediatric population. MATERIALS AND METHODS A total of 11 children, who had undergone micro-URS between September 2015 and April 2016 with the indication of distal ureteral calculi in two referral centers, were retrospectively evaluated. The procedures were performed with the patient in the lithotomy position under general anesthesia using the standard URS technique with a micro-ureteroscope that has a caliber of 4.85 Fr all along its length. Demographics, perioperative data, and outcomes were assessed. RESULTS Right (n=6) and left (n=8) ureteral stones were detected in the respective number of patients. The mean age of the children was calculated as 55.1months (range, 6-161months). The median stone size was 10.5mm (range, 6-24mm). The median operative time was 36.8min (range, 23-68min). A double 3 stent was implanted in 3 of 11 patients because of severe edema. As a postoperative complication mild hematuria (Clavien grade 1) was observed in one case and resolved spontaneously. Intraoperative minor or major complication did not occur in any of the cases. The mean hospitalization time was determined as 21.4h (range, 10-28h). Stone-free status was accomplished in all patients in the final assessment. CONCLUSION The outcomes of our series show that micro-URS can be used safely and effectively in the treatment of pediatric distal ureteral stones. Further prospective and comparative studies comparing instruments of different size are warranted.

Abstract
BACKGROUND In recent years, the incidence of urinary stone disease reportedly has been increasing. The use of shockwave lithotripsy has seen low success rates, the inefficacy of a single session, and the need for general anaesthesia in children; additionally, children are exposed to radiation. These suboptimal treatment conditions have all led to ureteroscopy (URS) becoming the treatment method of choice for paediatric ureter stones. The aim of this study is to examine the effectiveness of 4.5-Fr URS when used on children younger than 1 year of age. PATIENTS AND METHODS The operation results of 34 patients (12 girls and 22 boys) who had undergone intervention for ureter stones at our clinic were retrospectively evaluated. For URS, a 4.5-Fr semi-rigid ureteroscope was used; a Holmium:YAG laser machine was used as a lithotripter. RESULT The mean patient age was 9.6 months (range 4-12 months) (Table). The mean stone surface area was 25.39 mm2 (range 11.84-84.78 mm2). In six cases, a ureteral catheter was inserted, because of minimal oedema in the ureters; in nine cases, a Double J (DJ) stent was inserted. The mean operation time was 45.3 min (range 22-87 min). In the first week of control with urinary ultrasonography and kidney-ureter and bladder radiograph, a stone-free condition was determined in 28 (82.3%) patients. In two cases-in which sufficient fragmentation could not be achieved, because of minimal bleeding during operation-during the exertion of a DJ stent, another URS was performed. In the first postoperative month, a stone-free condition was established in 32 (94.1%) patients. The mean hospital stay period was 28.6 h (range 12-72 h). There were seven cases (20.5%) with Clavien II-III complications. CONCLUSION Use of a ureteroscope is safe and effective with paediatric patients: we found that a 4.5-Fr ureteroscope can be safely used on children under 1 year of age. We therefore consider a 4.5-Fr ureteroscopic instrument to be an appropriate tool for treating URS in children within this age range.

Abstract
OBJECTIVE We aimed to investigate the ureter stone treatment results performed by using different- caliber semirigid ureteroscopes (URS). MATERIAL AND METHODS Adult patients who were treated for ureteral stones by a single endoscopist between January 2000 and March 2015 were analyzed. The patients were divided into 3 groups in accordance with the caliber of the ureteroscope used: 10/10.5 F Storz (Karl Storz, Tuttlingen, Germany) (January 2002-January 2005) URS was used in group 1, 8.9/9.8 F Storz (February 2005-December 2011) URS was used in group 2, and 6/7.5 FWolf (Richard Wolf, Knittlingen, Germany) (January 2012-March 2015) URS was used in group 3. Patients' age and gender, size and site of stones, stone-free rates (SFR), intra- and perioperative complication rates, and durations of surgery were compared among the groups. Intraoperative complications were classified according to modified Satava, and perioperative complications were classified according to modified Clavien classification systems. RESULTS A total of 2461 patients treated for ureteral stones were analyzed. There were 583 patients in group 1 (10/10.5 F Storz), 1302 patients in group 2 (8.9/9.8 F Storz), and 576 patients in group 3 (6/7.5 F Wolf). SFR were 83.7%, 87.4%, and 92.2% in groups 1, 2, and 3, respectively (p=0.01). Duration of surgery was 30.34±10.36 min in group 1, 31.61±10.10 min in group 2, and 42.40±7.35 min in group 3 (p=0.01). The overall complication rates classified according to modified Satava classification were 10.8%, 7.6%, and 6.9% (p=0.01) while grade 3 modified Satava complication rates were 1.9%, 1.5%and 0.5% in groups 1, 2, and 3, respectively (p=0.01). CONCLUSION In this study, we found that more frequent use of a small- caliber URS resulted in a longer duration of surgery and an increased rate for JJ stent insertion, however it facilitated a safer and more successful ureteroscopy procedure.

Abstract
OBJECTIVE To investigate the effectivity of 4.5F ultrathin ureteroscope (UT-URS) without any need for active or passive dilation in the treatment of adult patient population in whom ureteral orifices cannot be engaged using conventional URS. MATERIALS AND METHODS Among a total of 512 adult patients who had undergone URS between April 2012 and November 2015 in our department for diagnostic or therapeutic purposes, 43 (8.4%) patients required ureteral dilation because we could not engage ureteral orifice. In adult patients in whom we could not engage ureteral orifice with 7.5F and 8F semirigid URS, we tried to complete the operation using 4.5F UT-URS without resorting to dilation. Age and gender of the patients, indication for operation, stone size, location, operative times, laterality of stone(s), stone-free rates, length of hospital stay, and complications were recorded. RESULTS Mean age of the patients was 34.5 ± 11.2 (21-66) years. The patients had undergone operations for ureteral stone (n = 39), unexplained hydronephrosis (n = 2), and ureteral stenosis (n = 2). Mean stone size was 8.2 ± 2.3 (4-18) mm. Mean operative time was 64.2 ± 13.5 minutes. In 37 of 39 patients, a complete stone-free rate (94.8%) was achieved. Mean length of hospital stay was 8.9 ± 5.8 hours. CONCLUSION It has been demonstrated that in an adult patient population in whom ureteral orifices cannot be engaged using conventional URS, ureteral access could be achieved with 4.5F UT-URS without any need for dilation. At the same time, use of 4.5F UT-URS resulted in an acceptable treatment success and lower complication rates in most of these patients without the need for a second session.

Abstract
BACKGROUND Urinary stones disease is becoming more common not only in adults but also in children. Most cases are resolved with extracorporeal shock wave lithotripsy, but miniaturization of endoscopes has increased the use of ureteroscopy in resolving ureteral stones, most notably in children. CASE PRESENTATION This presentation focuses on two cases of microureteroscopy. In both cases, the presence of lithiasis in the pelvic ureter was suspected to be the cause of ureter hydronephrosis, and a microureteroscopy was performed for treatment purposes. MicroPerc set 4.85F sheath was used to explore the pelvic ureter, thus avoiding the need to dilate the ureteral meatus or having to use the safety guide. Patients did not require a postoperative stent and were discharged within 24 hours of the procedure. CONCLUSION Use of microureteroscopy proved satisfactory in the two cases of children and it allows diagnosis and treatment of ureteral pathology in pediatric patients.

Abstract
The increasing incidence of pediatric stone disease has coincided with significant advances in technology and equipment, resulting in drastic improvements in management. Miniaturization of both ureteroscopes and percutaneous nephrolithotomy (PCNL) equipment has facilitated access to the entirety of the urinary tract and has made ureteroscopy a first-line therapy option along with shock-wave lithotripsy for kidney and ureteral stones. Advances in PCNL have decreased patient morbidity while preserving stone clearance rates. In this review, the advances in operative approach for ureteroscopy and PCNL in children and its applicability to current surgical management of pediatric stone disease are discussed.
