Abstract
A ureterocele is a congenital cystic dilatation of the intravesical ureter that may affect either a single system kidney or the upper pole of a duplex system. The position of ureteral orifice correlates with function of associated renal moiety. Ureteroceles associated with good renal function and prompt drainage or ureteroceles associated with no renal function can be managed nonoperatively. Endoscopic puncture of ureteroceles addresses most cases; iatrogenic reflux may rarely require secondary surgery. Robot-assisted laparoscopic upper pole nephroureterectomy and ureteroureterostomy procedures are rarely associated with complications.

Abstract
Introduction: Cerebral and renal regional oxygen saturation (C-rSO2 and R-rSO2, respectively) were monitored using near-infrared spectroscopy in pediatric patients (range: 0.3-14.3 years) during minimally invasive surgery (MIS) taking at least 3 hours performed by laparoscopy (Lap), thoracoscopy (Tho), or retroperitoneoscopy (Ret) from January 2019 to December 2021. Materials and Methods: Criteria compared were operative time, preoperative/intraoperative hemoglobin, blood loss, mean arterial pressure, arterial partial pressure of carbon dioxide (PaCO2), peripheral oxygen saturation (SpO2), C-rSO2, and R-rSO2. Pathological desaturation (PD) was defined as >20% decrease from baseline, and statistical significance as P < .05. Results: Subjects (n = 79) were similar for gender, age, and body mass index. MIS procedures were: Lap = 45, Tho = 20, Ret = 14; one Lap case required conversion for severe adhesions, not PD. Intraoperative PaCO2 (mmHg) was significantly higher in Tho (maximum: 59.5 ± 17.0, minimum: 39.9 ± 7.5) versus Lap (maximum: 39.9 ± 5.1, minimum: 34.6 ± 3.9) and Ret (maximum: 37.8 ± 4.2, minimum: 35.0 ± 3.3); P < .0001 (maximum), P = .0013 (minimum). Minimum intraoperative SpO2 was significantly lower in Tho (P < .0001). Mean operative times were significantly shorter in Tho (259 ± 114 minutes) versus Lap (433 ± 154 minutes) and Ret (342 ± 100 minutes); P < .0001, respectively. PD was absent during Ret (C-rSO2: 0/14 = 0% and R-rSO2: 0/14 = 0%). Differences in PD for Lap (C-rSO2: 7/45 = 15.6% and R-rSO2: 10/45 = 22.2%) and Tho (C-rSO2: 9/20 = 45.0%, and R-rSO2: 7/20 = 35.0%) were significant; P = .0028 for C-rSO2 and P = .0497 for R-rSO2. Hemoglobin and blood loss were similar. Conclusions: PD was absent during Ret, despite longer operative times. If Ret is indicated for a procedure, neurodevelopmental sequelae of MIS could be minimized.

Abstract
Optimal management of duplication anomalies may include an upper or lower tract surgical approach. In the contemporary era, the robot-assisted laparoscopic heminephrectomy (RALHN) and robot-assisted laparoscopic ipsilateral ureteroureterostomy (RALIUU) are viable interventions predicated on clinical, institutional and surgeon preferences. We present a multi-institutional comparative analysis aiming to compare the outcomes of RALHN and RALIUU to see if either of the approaches confers an advantage over the other in treating duplex renal anomalies needing intervention. We completed a retrospective review of consecutive children undergoing RALIUU at Hospital A and RALHN at Hospital B from January 2009 to March 2017. The primary outcome was 'surgical success' defined by the resolution of clinical symptoms, improved radiological parameters, and no unplanned subsequent interventions till the time of study completion. Secondary outcomes included operative parameters, complications, and subsequent urinary infections. There were 39 RALIUU and 28 RALHN. Baseline demographic and clinical parameters across two cohorts were similar. The primary outcome of 'surgical success' was 100% across both cohorts. There were no major surgical complications, and the incidence of postoperative urinary tract infection was minimal and similar for both groups. Operative time favored RALHN; blood loss and analgesic requirements were minimal in both cohorts. Both RALIUU and RALHN are definitive surgical interventions in children with complex duplex moieties, delivering satisfactory surgical outcomes with a low complication profile and marginal differences in the postoperative patient outcomes. This pilot bi-institutional study provides the basis for a larger collaboration to further define optimal techniques, standardize surgical care pathways, and interrogate long-term outcomes.

Abstract
OBJECTIVE To analyse the outcomes of retroperitoneoscopic upper and lower moiety hemi-nephroureterectomy (HNU) and to assess the different variables that may have an impact on outcome; remnant moiety damage, morbidity and the need for secondary surgery. METHODS Prospectively recorded data of retroperitoneoscopic HNU's performed by a single surgeon from 2005 to 2018 were analysed. Patients were split into 2 groups according to moiety affected (UMHNU and LMHNU). Clinical presentation, underlying pathology, remnant moiety DRF on renal scintigraphy, and need for further surgery were recorded. Detailed operation notes were studied regards to renal vasculature, degree of dilatation, inflammatory changes and operative difficulties encountered. Renal loss was defined as remnant moiety DRF <10% post-operatively. Change in DRF was assessed regards to the moiety, pathology and age at surgery (<1 year, 1-2 years and ≥2 years). UMHNU group was further sub-divided into 3 subgroups: ureteroceles, ectopic ureters and 'other' pathology. Statistical analysis was performed using Fishers Exact test; findings were considered statistically significant at p < 0.05. RESULTS 78 operations met the inclusion criteria on 75 patients (3 bilateral). There were no conversions to open, and 67% were performed as day-case procedures (53/78 patients). In 91.2% (71/78) patients the procedure was definitive in resolving pathology and symptoms. 7 patients needed further procedures after HNU, 5 for ureterocele/ureteric stump. Overall, there was remnant moiety renal loss in 5.1% (4/78) patients, all with UM surgery (3 ectopic ureters and 1 ureterocele). All 4 operations were recorded prospectively as 'difficult operations' due to grossly dilated UM ureter/pelvis measuring >2 cm in diameter. 2 patients had a thinned out lower moiety (LM) sitting on top of the UM renal pelvis like a pancake with all vessels stretched over this dilated pelvis/ureter causing difficulty in accurate identification. There was intra-operative concern about some damage to LM vessels in 3 patients. Age <1year was also related to increased renal loss (2/8 patients <1 year, 1/25 patients 1-2 years, 1/45 patients ≥2 years of age P = 0.005). CONCLUSION Retroperitoneoscopic LMHNU is a safe and definitive procedure with rapid recovery and minimal scarring. UMHNU has higher rates of remnant moiety loss due to more complex renal pathology, but remains a safe, successful operation on the majority of patients. Renal damage was also related to age <1year (p = 0.005) and re-operation risk after UMHNU correlated to the presence of ureterocele (p = 0.003).

Abstract
Duplication anomalies of the kidney represent common congenital malformations of the urinary tract. A duplex kidney has often one pole that is poorly or nonfunctioning. In this last case, surgery may be indicated to remove the nonfunctioning pole. The most common indications for partial nephrectomy in pediatrics include symptomatic vesicoureteral reflux to the nonfunctioning pole and/or ectopic ureter or ureterocele causing urinary incontinence. In this article, we describe the technique of laparoscopic partial nephrectomy in infants and children with duplex kidney. A surgical procedure properly executed following critical technical steps is the key factor for the success of surgery.

Technical standardization of ICG near-infrared fluorescence (NIRF) laparoscopic partial nephrectomy for duplex kidney in pediatric patients. World J Urol 2021; 39:4167-4173.

Abstract
Purpose This study aimed to standardize the operative technique of indocyanine green (ICG) near-infrared fluorescence (NIRF) laparoscopic partial nephrectomy (LPN) and compare it with the standard technique. Methods In the last 4 years, we performed 22 LPN (14 right-sided, 8 left-sided) in children with non-functioning moiety of duplex kidney. Patients included 12 girls and 10 boys with a median age of 3.9 years (range 1–10). Patients were grouped according to the use of ICG-NIRF: G1 included 12 patients operated using ICG-NIRF and G2 included 10 patients receiving the standard technique. We standardized the technique of injection of ICG in three different steps. Results The median operative time was significantly lower in G1 [87 min (range 68–110)] compared with G2 [140 min (range 70–220)] (p = 0.001). One intra-operative complication occurred in G2. At post-operative ultrasound (US), the residual moiety was normal in all patients. An asymptomatic renal cyst related to the site of surgery was visualized at US in 8/22 (36%), with a significantly higher incidence in G2 (6/10, 60%) compared with G1 (2/12, 16.6%) (p = 0.001). Renogram demonstrated no loss of function of residual moiety. No allergic reactions to ICG occurred. Conclusion ICG-NIRF LPN is technically easier, quicker, and safer compared with the standard technique. The main advantages of using ICG-NIRF during LPN are the clear identification of normal ureter, vasculature of non-functioning pole, and demarcation line between the avascular and the perfused pole. The main limitation of ICG technology remains the need for specific laparoscopic equipment that is not always available.

Abstract
BACKGROUND There appear to be various patterns of sidedness with relation to the common urogenital malformations observed in pediatric urology. The objective of this statistical review was to synthesize this data and to assess if these patterns are significant. MATERIALS AND METHODS Eighteen urogenital conditions were investigated and for each condition the five largest studies that noted laterality were included. The sidedness of each condition was then analysed for statistical significance. RESULTS Three conditions had a statistically significant higher proportion on the right side: palpable undescended testis (63%, p = 0.0002), inguinal hernia (59%, p = 0.0001) and hydrocele (60%, p = 0.003). Three conditions were significantly more common on the left side: impalpable undescended testis (59%, p = 0.0008), renal agenesis (54%, p = 0.02) and vesico-ureteric junction obstruction (71%, p < 0.0001) while both pelvi-ureteric junction obstruction (62%, p = 0.09) and absent vas deferens (61%, p = 0.11) were trending towards significance. CONCLUSIONS Various urogenital malformations display a predilection for one side. Proximal malformations tend to be more frequently seen on the left side, where as inguinoscrotal malformations are more frequently observed on the right. There is an increasing body of literature regarding aetiological factors for these conditions. However, our current understanding of the pathophysiology of these conditions does not completely explain this pattern of observation.

Abstract
Introduction The most common indication for retroperitoneoscopy in children is poorly functioning kidney, related to reflux or obstruction. Few pediatric urologists attempt to conduct a mass resection operation under retroperitoneoscopy, especially in infants with oncological diseases. Aim In this study, we describe our experience in a series of resection operations under retroperitoneoscopy to demonstrate its safety and efficacy in children, especially in the treatment of pediatric urology tumor. Material and methods A retrospective review of 18 consecutive retroperitoneoscopic resection operations from December 2017 to July 2019 was made. Then a comparison study between retroperitoneoscopy and transperitoneal laparoscopy for exclusively oncological patients was conducted. Results Retroperitoneoscopic surgery was successfully performed on 18 patients, 11 having solid tumors, 2 with cysts, and 5 with nonfunctioning or poorly functioning kidneys. The mean age was 69.5 ±46.9 months. The mean operative time was 138.6 ±57.7 min, while the mean size of the mass was 6.4 ±3.8 cm in the largest diameter. Two patients were converted to open surgery because of large diameter of the mass. The 11 solid tumors which were operated on by retroperitoneoscopic surgery were then compared with 13 consecutive oncological patients undergoing transperitoneal laparoscopy. Retroperitoneoscopy has a lower transfusion rate (p < 0.05) and faster recovery (p < 0.01) compared to transperitoneal laparoscopy. Conclusions This study demonstrates that the resection operation of a renal or adrenal specimen under retroperitoneoscopy is feasible and safe in children. It is useful not only to treat patients with benign diseases but also in oncological patients. Retroperitoneoscopy is a recommended surgical approach for children.

Abstract
Background: To report our experience with retroperitoneal robot-assisted laparoscopic upper pole heminephrectomy in adult patients with duplex kidneys. Methods: We retrospectively reviewed the medical records of 7 patients who underwent retroperitoneal robot-assisted laparoscopic upper pole heminephrectomy at our institution between September 2014 and July 2017. Of the robot-assisted laparoscopic procedures, 5 were on the left and 2 on the right side. Results: All patients underwent robot-assisted laparoscopic surgery successfully in a totally retroperitoneal manner without conversion to open surgery. The mean operative time was 175 mins (range 140-270). The mean estimated blood loss was 84 mL (range 20-200). The mean postoperative hospital stay was 7 days (range 5-9). No major intraoperative and postoperative complications occurred. All patients had a resolution of their presenting symptoms after surgery at a mean follow-up of 24 months (range 14-38). Conclusion: Our initial clinical experience suggests that robot-assisted laparoscopic upper pole heminephrectomy using a retroperitoneal approach for a duplex kidney appears to be safe with acceptable perioperative outcomes.

Abstract
BACKGROUND Renal duplication is a common deformity of the urinary system, with an incidence of approximately 1/125 in children. Symptomatic patients with hydronephrosis, vesicoureteral reflux, or incontinence may require surgical interventions. Laparoscopy and retroperitoneoscopy are the two main accesses for partial nephrectomy.
CASE SUMMARY A 9-year-old child was admitted to the hospital for hydronephrosis of the left kidney. Ultrasonography showed that the left kidney was larger, approximately 12.6 cm × 6.3 cm × 5.5 cm in size, with visible separation of the pelvis and an obviously separated lower portion. The upper segment of the left ureter was dilated (approximately 2.6 cm in width), and no significant dilation was observed in the middle and upper segments. The right kidney and ureter were normal. Primary diagnosis was left renal duplication malformation and hydronephrosis. Retroperitoneal laparoscopic nephrectomy and ureterectomy were performed. Intraoperative exploration revealed a dilated pelvis and thin renal parenchyma at the lower pole of the left kidney. The upper left kidney was smaller than normal, and the pelvis and ureter were larger than normal. The renal artery was blocked for 40 min. A hemolock was used to clamp down the kidney ureter, and a drainage tube was retained in the retroperitoneal cavity. The operation was uneventful, and the estimated amount of blood loss was 100 mL. Total abdominal drainage amount was 116 mL. The drainage tube was removed on postoperative day (POD) 3 and the patient was discharged on POD6. The pathological diagnosis confirmed the atrophy of the renal parenchyma, the dilation of the renal pelvis, hydronephrosis, and ureteral cystic dilation.
CONCLUSION The retroperitoneoscopic approach for partial nephrectomy is feasible and effective in selective pediatric patients with a duplex kidney.

Abstract
INTRODUCTION Recent reports in the literature suggest an increased risk of complications with retroperitoneal as opposed to transperitoneal approach to partial nephrectomy (PN) and total nephrectomy (TN). We are a large unit performing predominantly retroperitoneoscopic PN and TN. We aim to review our outcomes and perform analysis to elucidate the predictors of complications following the retroperitoneal approach for extirpative kidney surgery. METHODS We performed a single center retrospective review of children undergoing MIMS TN and PN between 2005 and 2015. Variables were tested for association with outcomes using Chi2 and Spearman's Rho correlation. RESULTS We performed 173 MIMS nephrectomies, 119 total and 54 partial. Median age and weight were 5 years (6 months to 18 years) and 24.9 kg (7.7 to 85 kg) and operative time 147 min. There were 4 conversions and 17 postoperative complications. 19.6% children required further surgery, including 8 completion stumpectomies. Retroperitoneal approach did not have increased risk compared to transperitoneal for need of further surgery. Partial nephrectomy was not associated with higher rate of intraoperative complication or LOS. Predictors of intraoperative complication were vessel closure technique. Associations with need for further surgery were: ESRF, contralateral disease, bladder dysfunction, presence of PD catheter, and need for concomitant procedure. CONCLUSION Our conversion rate (1.9%) and need for further surgery (13.1%) following the retroperitoneal approach to the kidney are favorable to the literature. Need for reoperation is often associated with the underlying diagnosis and the natural sequelae of the disease process. LEVEL OF EVIDENCE IV.

Abstract
Objectives: Outcomes evolution during the learning curve of laparoscopic transperitoneal heminephrectomy in children with a duplex kidney. Materials and Methods: The data of 33 children, operated on between 2008 and 2017, with complicated duplex kidney, were subjected to a retrospective analysis. All patients were operated on by transperitoneal access using the laparoscopic technique. Patients were divided into two groups (1: subsequent operation 1-16, and 2: operations 17-33) to evaluate the learning curve. Results: There was no need for conversion. Total complications occurred in seven patients in Group 1 and 2 patients of Group 2 (p < 0.05). Two patients (6%) (both upper pole heminephrectomies) required reoperation to remove the ureter stump because of recurrent UTIs due to undiagnosed VUR to the stump (1 from each of Groups 1 and 2). Prolonged urine leakage (over 4 days) was observed in four patients (12%; all from group 1); in three patients, conservative treatment was successful, while the placement of a DJ catheter was needed in the fourth. A significant decrease of kidney function (>6%) in scintigraphy was observed in two of the 15 patients after the surgery. The time of surgery decreased from 140 (range 85-185) min in Group 1 to 125 (range 100-150) min in Group 2 (p < 0.05). Conclusions: Laparoscopic heminephrectomy is connected to the learning curve. Most complications occurred in the first 16 operations. With increasing experience, the time of operation decreased. In patients with reflux to the upper pole, referred for upper pole heminephrectomy, it is necessary to consider the removal of the ureter to the level of the vesicoureteral junction.

Laparoscopic and robotic-assisted repair of retrocaval ureter in children: a multi-institutional comparative study with open repair. World J Urol 2018; 37:1941-1947.

Abstract
PURPOSE This retrospective study aimed to report a multi-institutional experience with laparoscopic and robotic-assisted repair of retrocaval ureter in children and to compare outcome of minimally invasive surgery (MIS) with open repair. METHODS The records of all children, who underwent MIS and open repair of retrocaval ureters in six international pediatric urology units over a 5-year period, were retrospectively collected. Data were grouped according to the operative approach: a laparoscopic group (G1) included five patients, a robotic-assisted group (G2) included four patients, and an open group (G3) included three patients. The groups were compared in regard to operative and postoperative outcomes. RESULTS At follow-up, all patients (one G1 patient after redo-surgery) reported complete resolution of symptoms and radiologic improvement of hydronephrosis and obstruction. In regard to postoperative complications, one G1 patient developed stenosis of anastomosis and needed re-operation with no further recurrence (IIIb Clavien). G2 reported the lowest average operative time (135 min) compared to G1 (178.3 min) and G3 (210 min). MIS (G1-G2) reported a significantly better postoperative outcome compared to open repair (G3) in terms of analgesic requirements, hospitalization, and cosmetic results. CONCLUSIONS The study outcomes suggest that MIS should be the first choice for retrocaval ureter because of the minimal invasiveness and the better cosmetic outcome compared to open surgery. Furthermore, our results showed that robotic-assisted reconstruction was technically easier, safer, and quicker compared to laparoscopic repair, and for these reasons, it should be preferentially adopted, when available.

Abstract
BACKGROUND Very limited informations are currently available about the best approach to perform retroperitoneoscopic surgery. This multicentric international study aimed to compare the outcome of lateral versus prone approach for retroperitoneoscopic partial nephrectomy (RPN) in children. METHODS The records of 164 patients underwent RPN in 7 international centers of pediatric surgery over the last 5 years were retrospectively reviewed. Sixty-one patients (42 girls and 19 boys, average age 3.8 years) were operated using lateral approach (G1), whereas 103 patients (66 girls and 37 boys, average age 3.0 years) underwent prone RPN (G2). The two groups were compared in regard to operative time, postoperative outcome, postoperative complications, and re-operations. RESULTS The average operative time was significantly shorter in G2 (99 min) compared to G1 (160 min) (p = 0.001). Only 2 lateral RPN required conversion to open surgery. There was no significant difference between the two groups as for intraoperative complications (G1:2/61, 3.3%; G2:6/103, 5.8%; p = 0.48), postoperative complications (G1:9/61, 14.7%; G2:17/103, 16.5%; p = 0.80), and re-operations (G1:2/61, 3.3%; G2:4/103, 3.8%; p = 0.85). Regarding postoperative complications, the incidence of symptomatic residual distal ureteric stumps (RDUS) was significantly higher in G2 (7/103, 6.8%) compared to G1 (1/61, 1.6%) (p = 0.001). Most re-operations (4/6, 66.6%) were performed to remove a RDUS . CONCLUSIONS Both lateral and prone approach are feasible and reasonably safe to perform RPN in children but the superiority of one approach over another is not still confirmed. Although prone technique resulted faster compared to lateral approach, the choice of the technique remains dependent on the surgeon's personal preference and experience. Our results would suggest that the lateral approach should be preferred to the prone technique when a longer ureterectomy is required, for example in cases of vesico-ureteral reflux into the affected kidney moiety, in order to avoid to leave a long ureteric stump that could become symptomatic and require a re-intervention.

Abstract
BACKGROUND Conventional laparoscopy (CL) using 3-5 mm ports has become the goldstandard for pediatric nephrectomy (N), heminephrectomy (HN) and heminephrecto-ureterectomy (HNU) for many years now. Recently the spectrum of minimal invasive surgery (MIS) has been extended by variants like laparoendoscopic single-site surgery (LESS) or robot-assisted surgery (RAS). However such technical developments tend to drive surgical euphoria and feasibility studies, but may miss adequate academic research about function and proven patients' benefits. This article delivers a comprehensive analysis of present pediatric studies comparing at least two MIS approaches to N, HN and HNU. METHODS A systematic literature-based search for studies published between 2011-2016 about CL versus LESS or RAS for pediatric N, HN, and HNU was performed using multiple electronic databases and sources. The level of evidence was determined using the Oxford Centre for Evidence-based Medicine (OCEBM) criteria. Single arm observational studies about N, HN or HNU using CL, LESS or RAS as well as publications including adult patients were excluded. RESULTS A total of 11 studies met defined inclusion criteria, reporting on CL versus LESS or RAS. No studies of OCEBM Level 1 or 2 were identified. Performing CL for N and HN limited evidence indicated reduced analgesic requirements and shorter hospital stay over open surgery, but longer operating time. Preservation of renal function of the remaining moiety after CL-HN was 95%. Importantly, of patients losing their remaining moiety, median age at surgery was 9 months (range, 4-42 months), and all except 1 (6/7) had an upper pole HN. Several authors compared TNP versus RPN access for CL and confirmed a longer operating time for RPN versus TPN-NU. Moreover one study reported a longer ureteric stump in RPN versus TPN-HNU (range, 2-5 cm vs. 3-7 mm). Disadvantages of LESS or RAS over CL were longer operative time and higher total costs (RAS). There were no differences regarding complications, success rates, or short-term outcomes between pediatric RAS versus CL. No long-term studies about preservation of renal function or length of ureteric stump using LESS or RAS could be retrieved. CONCLUSIONS Several approaches to MIS-NU and HNU are available today. CL represents the method of choice for any age group. TPN or RPN can be chosen according to age of the patient. LESS and RAS offer distinct advantages, but also lack evident patients' benefits over CL at present. Hopefully, as pediatric MIS advances over the next decade, larger studies comparing CL, LESS or RAS directly for pediatric NU and HNU will be published to gain a higher level of evidence what's really best for the child.

Abstract
The emergence of minimally invasive surgery about 20 years ago revolutionized pediatric urology. Advances in pediatric devices allowed the widespread use of minimally invasive techniques in almost the entire range of pediatric urology. In this context, laparoscopy and later retroperitoneoscopy were developed and applied in a wide spectrum of urological diseases. Both approaches have since presented benefits and disadvantages that have been documented in various series. However, few comparative studies have been conducted. The aim of this review is to compare the two approaches and establish which is preferable in each field of pediatric urology.
