Abstract
OBJECTIVES To explore surgical, functional, and symptomatic outcomes in a series of patients who underwent robot-assisted laparoscopic Anderson-Hynes pyeloplasty (RALP) for ureteropelvic junction obstruction using the DaVinci Si surgical robotic system. METHODS Retrospective study including patients aged 16 years or older who underwent RALP from June 2016 to December2021. The following outcomes were recorded: operative outcome and complications [classified according to the Clavien-Dindo Classification (CD)] within 30 days of the procedure as well as 1 year success rate and restenosis during follow-up. RESULTS In total, 194 patients were available for analyses with a median follow-up of 4.5 (IQR 3.0-6.0) years. The primary indications were loss of kidney function (45%), pain (36%), infection (11%), kidney stone (6%), and others (2%). The median operation time was 134 min (IQR 112-159), the median length of stay was 2 days (IQR 2-2), and the median time with double-j stent postoperatively was 24 days (IQR 22-27). Overall, 65 out of 194 patients (33%) experienced a postoperative complication (12% CD I, 13% CD II, 8% CD IIIa or IIIb). The 1 year success rate was 92% for patients treated because of deteriorating renal function, 78% for patients treated because of symptoms, 82% for patients treated because of infections, and 78% for patients treated because of kidney stones. Seven percent of the patients presented a recurrent ureteropelvic junction stricture during follow-up. CONCLUSIONS In our experience, robot-assisted laparoscopic Anderson-Hynes pyeloplasty performed with the DaVinci Si system is a safe with a few major complications and acceptable success rate.

Int Urol Nephrol 2024; 56:1911-1918. [PMID: 38244116 PMCID: PMC11090959 DOI: 10.1007/s11255-023-03906-5] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/18/2023] [Accepted: 11/28/2023] [Indexed: 01/22/2024]
Abstract
BACKGROUND Laparoscopic ureteroplasty is an effective method for managing ureteropelvic junction obstruction. Despite its high success rate, there remains a subset of patients who do not experience improvement in the hydrops. METHODS The study retrospectively analyzed the data of 143 patients with ureteropelvic junction obstruction (UPJO) who underwent laparoscopic pyeloplasty (LP) in our hospital from January 2015 to May 2022. Logistic regression was used to analyze the risk factors of recurrence stenosis after UPJO. RESULTS Out of these patients, 119 had complete clinical data and follow-up records. Among these patients, restenosis occurred in nine cases after the operation. There was a significant statistical difference in blood loss (P < 0.05). Univariate and multivariate logistic regression analysis revealed that the preoperative separation degree of the renal pelvis, cystatin C, and intraoperative blood loss were potential risk factors for recurrent stenosis after primary LP. When divided by split renal function (SRF), the odds ratio (OR) was 7.850 (P = 0.044), indicating that it was an independent risk factor for postoperative restenosis. Similarly, the OR for stenotic segment length was 0.025 (P = 0.011), also indicating it as an independent risk factor for restenosis. The areas under the receiver operating characteristic curve for stenotic segment length and SRF were 0.9056 and 0.7697, respectively. CONCLUSION In our study, we identified that preoperative renal pelvis separation, cystatin C, and intraoperative blood loss were potential risk factors for postoperative restenosis. SRF and stenosis segment length were independent risk factors for postoperative restenosis.

Ureteropelvic junction obstruction and renal calculi: Simultaneous treatment by robot-assisted laparoscopic pyeloplasty and transcutaneous retrograde flexible ureteroscopy. Technique description and early outcomes. Prog Urol 2023; 33:279-284. [PMID: 36792487 DOI: 10.1016/j.purol.2023.01.006] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/28/2022] [Revised: 01/20/2023] [Accepted: 01/24/2023] [Indexed: 02/15/2023]
Abstract
BACKGROUND Ureteropelvic junction obstruction (UPJO) and renal calculi are associated in 20 to 30% of cases and treatment is mandatory. The simultaneous surgical management is a therapeutic challenge that is still a source of controversy. We describe our technique combining robot-assisted laparoscopic pyeloplasty and transcutaneous retrograde flexible ureteroscopy (fURS), assessing the feasibility of simultaneous treatment through an original technique. METHODS This single centre series reports our initial experience with 12 patients. From January 2014 to September 2018, 12 patients underwent robot-assisted laparoscopic pyeloplasty with simultaneous fURS for UPJO and renal calculi. Mean age was 46 years (24-68). 92% had multiple renal stones and the mean cumulative stone diameter was 31,3mm. Robot-assisted pyeloplasty was performed with peroperative transcutaneous retrograde fURS through a ureteral access sheath introduced in an incision on the bassinet through a subcostal trocar. Stone extraction was performed using a basket. RESULTS All patients underwent surgery successfully, achieving UPJ repair and complete stone extraction. Mean operating time was 92,5min (85-110). All reported Clavien-Dindo complications were grade 1. Non-contrast enhanced abdominal CT performed 1 month after surgery confirmed the absence of residual stones in all patients. Mean follow-up time was 10 months with no recurrence of UPJO. CONCLUSION This small series confirms the feasibility with good surgical results of concomitant robot-assisted laparoscopic pyeloplasty and transcutaneous retrograde fURS stone extraction. No major complications were observed. This technique is easily reproducible but requires 2 experienced urologists to be achieved in a contained operative time.

Abstract
Background The aim of this study is to compare the results of laparoscopic pyeloplasty and robot-assisted laparoscopic pyeloplasty in patients with ureteropelvic junction obstruction. Methods Between March 2008 and May 2019, the patients who underwent retroperitoneal laparoscopic or robotic-assisted laparoscopic pyeloplasty in our institution were retrospectively reviewed. Results Thirteen patients underwent laparoscopically, and 12 patients underwent robotic surgery. The significant difference was found in median operative time between laparoscopic group (296 minutes) and robotic group (199 minutes) (P = 0.001). The median time for drain removal in laparoscopic group was longer than robotic group (3 vs. 2 days, respectively, P = 0.029). Conclusion Laparoscopic and robot-assisted laparoscopic pyeloplasty is safe and excellent success rates in patients with ureteropelvic junction obstruction. However, our experience study suggested that robotic surgery improves a total operative time, decreases drain removal time and less intraoperative blood loss than laparoscopic approach.

Abstract
Introduction: Success rate of laparoscopic pyeloplasty for ureteropelvic junction obstruction (UPJO) in children is comparable with open pyeloplasty. Prolonged ileus and injury to adjacent viscera more often occurred in transperitoneal approach; however, longer operation time is noted in retroperitoneal approach. Purpose: This study presented a hybrid retroperitoneoscopic pyeloplasty (HRP), for congenital UPJO in infants weighing <10 kg. Materials and Methods: From February 2017 to June 2020, 10 HRP procedures were performed in 9 patients by 1 surgeon. Retroperitoneal dissection of the renal pelvis and the upper third ureter was first performed, followed by extracorporeal suturing for pyeloureterostomy. Results: Mean operative age and body weight were 4.23 ± 3.69 months and 6.18 ± 1.57 kg. Operative, CO2 inflation, and extracorporeal suture time were 147.9 ± 39.5, 40.6 ± 11.2, and 62.9 ± 26.1 minutes, respectively. Surgical outcome was confirmed by renal ultrasound and diuretic renogram. Postoperative follow-up duration was 15.2 ± 7.7 months. Three patients had postoperative febrile urinary tract infection and recovered after antibiotic treatment. Conclusion: In infants or smaller children with UPJO, the HRP procedure may be considered as an effective and minimally invasive alternative with shorter learning curve for inexperienced surgeons.

Transperitoneal versus retroperitoneal approaches of pyeloplasty in management of ureteropelvic junction obstruction: A meta-analysis. Asian J Surg 2021; 45:1-7. [PMID: 33867239 DOI: 10.1016/j.asjsur.2021.03.022] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/02/2020] [Revised: 03/04/2021] [Accepted: 03/26/2021] [Indexed: 02/08/2023] Open
Abstract
The aim of this study was to evaluate the benefits and safety of transperitoneal and retroperitoneal pyeloplasty for ureteropelvic junction obstruction by a meta-analysis. We searched the databases including PubMed, Cochrane Library and Embase database from their inception to December 1st, 2020. Relevant literatures comparing retroperitoneal pyeloplasty with transperitoneal pyeloplasty were identified. A meta-analysis was conducted with Revman 5.3. The main outcomes included success rate, operative time, hospital stay, conversion rate of open surgery, overall complications, and detailed postoperative complications/indicators. 15 studies with 1881 patients were included. The results revealed that there were no significant differences between two approaches in success rate [OR = 1.51, 95%CI (0.94, 2.41), p = 0.09], hospital stay [MD = 0.21, 95%CI (-0.12, 0.54), p = 0.21] and overall complications [OR = 1.07, 95%CI (0.76, 1.50), p = 0.69]. The retroperitoneal approach was associated with longer operative time [MD = -26.91, 95%CI (-40.97, -12.84), p < 0.001], higher conversion rate [OR = 0.23, 95%CI (0.11, 0.47), p < 0.001] than the transperitoneal approach. As for the detailed postoperative complications/indicators, there were no significant differences between two approaches in the urinary leak, mild hematuria, fever, UPJO recurrence, infection and subcutaneous emphysema, as well as split renal function, renal pelvis anteroposterior diameter. The funnel plots showed that there were no obvious publication biases in our analysis. Therefore, we concluded that transperitoneal and retroperitoneal approaches had similar benefits and safety in success rate, hospital stay, overall complications and detailed postoperative complications/indicators. However, retroperitoneal was associated with longer operative time and higher conversion rate than transperitoneal approach. With the limitations of our study, additional high-quality studies are still essential for further evaluation.

Abstract
Pyeloplasty is considered the gold standard for the management of ureteropelvic junction obstruction in cases of flank pain, recurrent stone formation or infection, and deteriorating renal function. Over the last two decades, minimally invasive techniques such as robotic (RALP) and laparoscopic pyeloplasty (LP) have become increasingly popular and have been moderately replacing the open approach. This paper aims to provide a comprehensive up-to-date review on safety, efficacy and outcomes regarding robotic repair of UPJO compared to the conventional laparoscopic procedure. RALP represents a viable and innovative alternative to conventional LP with a comparable success and complication rate both in adult and in paediatric fields. The robotic approach seems to add further technical advantages when compared to conventional LP but sustains a higher costs. Currently, the choice to adopt one of the different minimally invasive approaches depends on the surgeon's preference or experience, and on institutional availability.

Abstract
Objective We aimed to evaluate the results of laparoscopic pyeloplasty with concomitant pyelolithotomy and compare results with a cohort of patients undergoing laparoscopic pyeloplasty without pyelolithotomy. Materials and Methods We retrospectively reviewed records of 43 patients undergoing transperitoneal laparoscopic Anderson-Hynes dismembered pyeloplasty between December 2012 and July 2018 at our department. Eighteen patients (42%) underwent laparoscopic pyeloplasty with concomitant pyelolithotomy. The results of patients with renal stones were compared with 25 matched patients undergoing laparoscopic pyeloplasty without concomitant renal stones. Demographic data, operative and stone parameters were compared between the groups. Results The groups were similar regarding to demographic characteristics. All operations were completed laparoscopically with no conversions to open surgery. In 3 cases without renal stones and 15 cases with renal stones, transposition of the ureter due to crossing vessels was performed. The mean stone size was 13±5.24 mm, and the median number of stones was 1 (1-18). The success of laparoscopic pyeloplasty with and without pyelolithotomy was 93.3% and 92.9%, respectively, as confirmed by negative diuretic renogram at postoperative 3rd months. Overall stone-free rate after laparoscopic pyelolithotomy was 93.3%. Mean operative time was 222.6765.71 minutes vs. 219.11±75.63 minutes for the pyeloplasty with concomitant pyelolithotomy vs. pyeloplasty, respectively (p=0.88). Conclusions Laparoscopic pyeloplasty with concomitant pyelolithotomy is a safe and effective intervention with associated good cosmetic results and high stone-free rates without significant increase in operative time or complications.

Abstract
Pyeloplasty is one of the most common urological reconstructive interventions. Since the presentation of the first open pyeloplasty by Anderson and Hynes in 1949, the management of ureteropelvic junction obstruction has dramatically developed. The most immense progress was made in the 1990s with the introduction of laparoscopy. A multitude of new minimal surgical techniques have been introduced since then. In the last few years, the innovations were based on refinement of already-existing techniques and technology. With this aim, single-port surgery, three-dimensional vision for laparoscopy, robotic technology, and alternative techniques for creating the anastomosis-like fibrin glue have been introduced. This unsystematic review is timely, and the scientific interest is to present and discuss some of the latest advances in surgical techniques and different approaches for the intra- and post-operative management in pyeloplasty. To the best of our knowledge, this is the only review looking at the recent advances in urological surgical techniques for pyeloplasty during the last few years with a focus on new technology and surgical techniques.

Abstract
Objective: Pyeloplasty is considered the gold standard treatment for ureteropelvic junction obstruction (UPJO). However, the failure rate of pyeloplasty is as high as 10% and repeat pyeloplasty is more difficult. This study aimed to evaluate the efficacy of balloon dilatation for failed pyeloplasty in children. Materials and Methods: Between 2011 and 2017, 15 patients, aged 6 months to 14 years, were treated with balloon dilation for restenosis of UPJO after a failed pyeloplasty. Ultrasound and intravenous urography were used to evaluate the primary outcome. Success was defined as the relief of symptoms and improvement of hydronephrosis, which was identified by ultrasound at the last follow-up. Results: All patients successfully completed the operation, 13 patients by retrograde approach and 2 patients by antegrade approach. Thirteen patients were followed for a median of 15 (4 to 57) months and 2 patients were lost to follow-up. Resolution of the hydronephrosis was observed in 5 cases. The anteroposterior diameter (APD) of the pelvis decreased by an average of 12.4 ± 14.4mm. Eight patients needed another surgery. The average postoperative hospital stay was 1.78 ± 1.4 days. Two patients experienced fever after balloon dilation. No other complications were found. Conclusions: Balloon dilatation surgery is safe for children, but it is not recommended for failed pyeloplasty in that group of patients, owing to the low success rate.

Abstract
CASE DESCRIPTION A 4-year-old spayed female Beagle was evaluated because of a 2-month history of intermittent pollakiuria, stranguria, dysuria, and abdominal pain. A diagnosis of bacterial cystitis was initially made, but clinical signs persisted despite appropriate antimicrobial treatment, so the dog was referred for further evaluation and treatment. CLINICAL FINDINGS Abdominal ultrasonography revealed a large, thin-walled, cystic structure in the urinary bladder at the level of the expected right ureterovesicular junction that communicated with the uniformly dilated right ureter. Severe right-sided pyelectasia was also detected. A presumptive diagnosis was made of a right-sided orthotopic ureterocele with secondary hydroureter and pyelectasia. TREATMENT AND OUTCOME Cystoscopy revealed a large cystic structure in the region of the right ureterovesicular junction without obvious communication between the ureter and urinary bladder. Portable C-arm fluoroscopy was used to confirm the presence of an intramural orthotopic tract and to measure the diameter of the ureter and renal pelvis via retrograde contrast ureteropyelography. Complete laser ablation of the ureterocele was performed by incising it circumferentially near its base. Clinical signs resolved immediately following the procedure. Six weeks later, the dog remained free of clinical signs and abdominal ultrasonography revealed resolution of hydroureter with persistence of mild right-sided pyelectasia. CLINICAL RELEVANCE Cystoscopic-guided laser ablation of an orthotopic ureterocele secondary to ureterovesicular stenosis was a safe and effective minimally invasive treatment for the dog of this report, resulting in immediate and continued improvement of clinical signs and ultrasonographic changes. Laser ablation should be considered as an alternative to surgery for the treatment of orthotopic ureteroceles in dogs.

Abstract
OBJECTIVE To assess the feasibility and outcomes of laparoscopic pyeloplasty in children with complex ureteropelvic junction obstruction (UPJO) and compare to children with iso-lated UPJO without associated urinary tract abnormalities. MATERIAL AND METHODS Medical records of 82 consecutive children submitted to transperitoneal laparoscopic pyeloplasty in a 12-year period were reviewed. Eleven cases were con-sidered complex, consisting of atypical anatomy including horseshoe kidneys in 6 patients, pelvic kidneys in 3 patients, and a duplex collecting system in 2 patients. Patients were di-vided into 2 groups: normal anatomy (group 1) and complex cases (group 2). Demographics, perioperative data, outcomes and complications were recorded and analyzed. RESULTS Mean age was 8.9 years (0.5-17.9) for group 1 and 5.9 years (0.5-17.2) for group 2, p=0.08. The median operative time was 200 minutes (180-230) for group 1 and 203 minutes (120-300) for group 2, p=0.15. Major complications (Clavien ≥3) were 4 (5.6%) in group 1 and 1 (6.3%) in group 2, p=0.52. No deaths or early postoperative complications such as: urinoma or urinary leakage or bleeding, occurred. The success rate for radiologic improvement and flank pain improvement was comparable between the two groups. Re-garding hydronephrosis, significant improvement was present in 62 patients (93.4%) of group 1 and 10 cases (90.9%) of group 2, p=0.99. The median hospital stay was 4 days (IQR 3-4) for group 1 and 4.8 days (IQR 3-6) for group 2, p=0.27. CONCLUSIONS Transperitoneal laparoscopic pyeloplasty is feasible and effective for the management of UPJO associated with renal or urinary tract anomalies.

Abstract
Laser endopyelotomy (LEP) is considered as an option for the treatment of pelviureteric junction obstruction in adults. A comprehensive systematic search of the published literature was performed to assess the success rate and perioperative complications of LEP in the treatment of primary and secondary pelviureteric junction obstruction and to identify the factors that may have an impact on the success of LEP. The evidence available has significant limitations in terms of the heterogeneous study design and the definitions of outcomes. The average overall success rate of the pooled data was 75% with a mean follow-up of 29 months. Complications were predominately minor with an average rate of 12.5%.

Abstract
OBJECTIVE To compare the efficacy of transumbilical multiport (TMLP) and standard laparoscopic pyeloplasty (SLP) for the treatment of congenital ureteropelvic junction obstruction in children. METHODS Forty-eight patients were included in this matched-pair study. The TMLP applied three transumbilical incisions for one 5-mm and two 3-mm ports, whereas SLP was undertaken with traditional three-port technique. The demographic, perioperative, and follow-up data were retrospectively compared between TMLP (n=24) and SLP (n=24) groups. RESULTS Two groups were matched according to patient's age, gender, laterality, weight, and surgical indication. TMLP and SLP were successfully performed in all patients, without conversion to open procedure. There was no significant difference between both groups in intraoperative blood loss, time to oral feeding, time to normal activities, pain scores, or complication rates. Longer mean operative time (125.4±21.6 vs. 112.2±25.2 min; P=0.012) and better patient satisfaction (30.4±4.5 vs. 24.6±3.4; P=0.026) were noted in TMLP group than those in SLP group. Mid-term follow-up indicated no significant difference in postoperative alleviation of hydronephrosis or improvement of renal function. CONCLUSION TMLP is a feasible and efficient procedure for the management of congenital ureteropelvic junction obstruction in children, with comparative outcome and better cosmetic results than SLP.

IRANIAN JOURNAL OF PEDIATRICS 2016; 26:e4293.

Abstract
Background: Ureteropelvic junction obstruction (UPJO) is one of the most common causes of urinary tract obstruction in children. Several methods are used to diagnose upper urinary tract obstruction including renal ultrasonography (US), intravenous pyelogram (IVP), diuretic renography (DR), magnetic resonance urography (MRU) and antegrade or retrograde pyelography. Nowadays it is suggested to use diuretic renography as the best method for diagnosing of UPJO. There is no comparative study between IVP and DR scan for diagnosis of UPJO in children. Objectives: The aim of the present study was to compare IVP with furosemide injection and diuretic renography in diagnosis of clinically significant UPJO. Patients and Methods: This was a cross sectional study performed in 153 UPJO suspected children (121 boys, 32 girls) based on US findings in cases presented with urinary tract infection (UTI), prenatal hydronephrosis, abdominal/flank pain, abdominal mass and hematuria. Renal ultrasound was used as an initial screening tool for detection of urinary tract abnormality. Vesicoureteral reflux (VUR) was ruled out by voiding cystourethrography (VCUG). Serum creatinin, blood urea nitrogen, urinalysis and urine culture was screened in all cases. IVP with furosemide and DR were performed as soon as possible after the mentioned workup. Results: During a five year period, 46 out of 153 patients were diagnosed as UPJO based on diuretic renography: the age ranged from 4 months to 13 years (mean: 3.1 ± 0.78 years). There was a significant higher (76%) proportion of UPJO in the boys and in the left side (78%). The sensitivity of IVP with furosemide injection in diagnosis of UPJO was 91.3% whereas DR was accepted as standard for diagnostic procedure in diagnosis of UPJO. Conclusions: Although DR is accepted as the best method for diagnosis of UPJO, we found a small sensitivity difference between IVP and DR in kidneys with normal or near normal function. In many settings such as small cities lacking facilities for advanced isotope imaging technology, use of IVP with diuretic maybe an acceptable procedure for diagnosis of UPJO.

Abstract
OBJECTIVE We evaluated outcomes of our robot-assisted laparoscopic transperitoneal pyeloplasty (RALP) procedures. MATERIAL AND METHODS Between July 2011 and March 2014, 18 RALP procedures were performed at our instutition. Ureteropelvic junction obstruction (UPJO) diagnosis was made based on clinical presentation and intravenous urography. All patients underwent basal and diuretic isotopic renography to evaluate the degree of obstruction and impaired renal function. Anderson-Hynes dismembered pyeloplasty technique was used with a transperitoneal approach by using the da Vinci-S 4-arm surgical robot. Outcomes were assessed retrospectively. RESULTS Mean patient age was 31.3±11.7 (13-62) years. Male: female ratio was 9: 9. All procedures were primary surgeries. Of 18 patients, 10 (55.5%) had a crossing vessel and 8 (44.5%) had intrinsic obstruction. Mean operative time was 150.4±17.2 (115-185) minutes. Mean anastomosis time was 21.4±5.5 (10-33) minutes. Mean blood loss during the operation was 33.6±17.3 (10-60) cc. Mean hospital stay was 2.6±1.0 (1-6) days. No conversion to open surgery was required. No intraoperative and perioperative (0-30 days) complication occurred. Readmission rate during perioperative period was 0%. Median follow-up was 16.6±10.3 (3-35) months. Postoperative intravenous urography and renography showed improved results in all cases. CONCLUSION Due to our experience, RALP is a safe and feasible minimally invasive approach in patients with UPJO with excellent surgical and functional outcomes.

Abstract
We aimed to review studies comparing the outcomes of the laparoendoscopic single site (LESS) pyeloplasty with those of conventional laparoscopic pyeloplasty (CLP). A systematic review of the literature was performed according to the PRISMA (preferred reporting items for systematic reviews and meta-analysis) criteria. The methodological quality of the studies was rated according validated scales. The level of evidence (LE) was reported as described by the Oxford criteria. Preoperative demographic parameters and perioperative outcomes between the two surgical techniques were assessed. A meta-analysis of the included studies was performed. A total of 5 studies were elected for the analysis, including 164 cases, 70 (42.6%) of them being LESS and 94 (57.4%) being CLP. Four studies were observational retrospective comparative studies (LE: 3a-4); one was a prospective randomized controlled trial (LE: 2b). There was no significant difference in age, body mass index, gender, side and presence of the crossing vessel, between the groups. There was no significant difference regarding the operative time (weight mean difference [WMD]: −7.02; 95% confidence interval [CI]: −71.82–57.79; P = 0.83) and length of hospital stay (WMD: 0.04; 95% CI: −0.11–0.20; P = 0.58), whereas the estimated blood loss was statistically lower for LESS (WMD: −16.83; 95% CI: −31.79–−1.87; P = 0.03). The postoperative use of analgesic favored the LESS group but without reaching statistical significance (WMD: −7.52; 95% CI: −17.56–2.53; P = 0.14). In conclusion, LESS pyeloplasty offers comparable surgical and functional outcomes to CLP while providing the potential advantages of less blood loss and lower analgesic requirement. Thus, despite being more technically challenging, LESS pyeloplasty can be regarded as a minimally invasive approach for patients seeking fewer incisional scars.

Abstract
To demonstrate the safety and efficacy of combine laparoscopy and flexible ureteroscopy to treat ectopic pelvic kidneys with ureteropelvic junction obstruction (UPJO) and stones. 16 patients of ectopic pelvic kidneys with ureteropelvic junction obstruction and stones were treated with laparoscopy and flexible ureteroscopy (FURS). The operative time, required dose of tramadol, visual analog pain scale (VAPS), postoperative day, stone-free rates (SFRs), perioperative complications, and serum creatinine were evaluated. The SFRs were evaluated with noncontrasted renal computed tomography (CT). Intravenous pyelography (IVP) and CT scan were used to evaluate the UPJO. Stone-free status was defined as absence of stone fragments in kidney or the size of that is less than 3 mm. Operation time from 118 to 225 min, average time (171 ± 28) min; lithotomy time from 16 to 45 min, average time (32 ± 6) min. Average tramadol required at the first day postoperation was (118 ± 49.6) mg; at the second day was (78 ± 24.8) mg. VAPS score at 24 h (5.0 ± 0.7), VAPS score at 48 h (2.5 ± 0.8). Postoperative day (3.9 ± 0.6) days. Stone-free rate was 100%. Average serum creatinine was (88.7 ± 24.3) mol/L before surgery and (92.8 ± 21.6) mol/L after surgery. No major complication. No stone and obstruction recurrence in the follow-up of average 29.3 months. Combined FUR and LC is a good option for patient of ectopic pelvic kidney with renal stone and UPJO. From our initial experience, the SFRs and the effect of pyeloplasty are satisfactory and without major complication, the operative time is acceptable.

Abstract
The simultaneous surgical management of ureteropelvic junction obstruction (UPJO) with concomitant renal stones has evolved the last 20 years; hence, the ideal minimally invasive technique is still controversial. Laparoscopic and robot-assisted laparoscopic operations allow precise surgical maneuvers and were thought to simplify the reconstruction steps of the procedure, especially in the treatment of complex cases with large stones. The aim of this study was to summarize the available perioperative and functional outcomes of minimally invasive available techniques. A non-systematic review of the literature was performed using a free-text protocol in the MEDLINE database. The terms used were "ureteropelvic junction obstruction," "renal calculi" and "renal stones." Furthermore, other significant relevant studies cited in the reference lists of the selected papers were also evaluated in the structure of this review. Currently, available evidence suggests that both laparoscopic and robotic-assisted techniques offer excellent surgical solutions in the field of UPJO reconstruction and renal stones removal. In the hands of experienced surgeons, laparoscopic and robotic pyeloplasty with concomitant stone removal is a safe procedure with high stone-free rates and UPJ patency. Minimally invasive pyeloplasty should constitute the first choice of treatment for concomitant renal stones and ureteropelvic junction obstruction.

Abstract
Introduction Approximately one out of five patients with ureteropelvic junction obstruction (UPJO) present lithiasis in the same setting. We present our outcomes of simultaneous laparoscopic management of UPJO and pelvic or calyceal lithiasis and review the current literature. Methods Thirteen patients, with a mean age of 42.8±13.3 years were diagnosed with UPJO and pelvic or calyceal lithiasis. All patients were subjected to laparoscopic dismembered Hynes–Anderson pyeloplasty along with removal of single or multiple stones, using a combination of laparoscopic graspers, irrigation, and flexible nephroscopy with nitinol baskets. Results The mean operative time was 218.8±66 minutes. In two cases, transposition of the ureter due to crossing vessels was performed. The mean diameter of the largest stone was 0.87±0.25 cm and the mean number of stones retrieved was 8.2 (1–32). Eleven out of 13 patients (84.6%) were rendered stone-free. Complications included prolonged urine output from the drain in one case (Clavien grade I) and urinoma formation requiring drainage in another case (Clavien grade IIIa). The mean postoperative follow-up was 30.2 (7–51) months. No patient has experienced stone or UPJO recurrence. Conclusion Laparoscopy for the management of UPJO along with renal stone removal seems a very appealing treatment, with all the advantages of minimally invasive surgery. Concomitant renal stones do not affect the outcome of laparoscopic pyeloplasty, at least in the midterm. According to our results and the latest literature data, we advocate laparoscopic management as the treatment of choice for these cases.

Abstract
CONTEXT Over the last two decades, minimally invasive treatment options for ureteropelvic junction obstruction (UPJO) have been developed and popularized. OBJECTIVE To critically analyze the current status of laparoscopic and robotic repair of UPJO. EVIDENCE ACQUISITION A systematic literature review was performed in November 2012 using PubMed. Article selection proceeded according to the search strategy based on Preferred Reporting Items for Systematic Reviews and Meta-analyses criteria. EVIDENCE SYNTHESIS Multiple series of laparoscopic pyeloplasty have demonstrated high success rates and low perioperative morbidity in pediatric and adult populations, with both the transperitoneal and retroperitoneal approaches. Data on pediatric robot-assisted pyeloplasty are increasingly becoming available. A larger number of cases have also been reported for adult patients, confirming that robotic pyeloplasty represents a viable option for either primary or secondary repair. Robot-assisted redo pyeloplasty has been mostly described in the pediatric population. Different technical variations have been implemented with the aim of tailoring the procedure to each specific case. The type of stenting, retrograde versus antegrade, continues to be debated. Internal-external stenting as well as a stentless approach have been used, especially in the pediatric population. Comparative studies demonstrate similar success and complication rates between minimally invasive and open pyeloplasty in both the adult and pediatric setting. A clear advantage in terms of hospital stay for minimally invasive over open pyeloplasty was observed only in the adult population. CONCLUSIONS Laparoscopy represents an efficient and effective less invasive alternative to open pyeloplasty. Robotic pyeloplasty is likely to emerge as the new minimally invasive standard of care whenever robotic technology is available because its precise suturing and shorter learning curve represent unique attractive features. For both laparoscopy and robotics, the technique can be tailored to the specific case according to intraoperative findings and personal surgical experience.

Abstract
The development, advancement and clinical integration of robotic technology in surgery continue at a staggering pace. In no other discipline has this rapid evolution occurred to a greater degree than in urology. Although radical prostatectomy has grown to become the prototypical application for the robot, the role of the robot in renal surgery remains controversial. Herein we review the literature on robotic renal surgery. A comprehensive PubMed literature search was performed to identify all published reports relating to robotic renal surgery. All clinically related articles involving human participants were critically appraised in this review. Fifty-one clinical articles were included, encompassing robot-assisted pyeloplasty, nephrectomy, nephroureterectomy, living-donor nephrectomy and partial nephrectomy. Feasibility has been shown for each of these procedures. Robot-assisted techniques have been described for almost all renal-related procedures. However, the intersect between feasibility and necessity as it pertains to robotic renal surgery has yet to be defined. Also, the high cost of surgical robotic technology mandates critical appraisal before adoption, especially in a publicly funded health care system, such as the one present in Canada.

Abstract
With increasing experience and availability of the da Vinci® robotic surgery system there has been an extension of the indications from initially exclusively ablative interventions, such as nephrectomy and radical prostatectomy to reconstructive interventions, such as pyeloplasty, bladder augmentation and urinary diversion. Laparocopic pyeloplasty has been established for both adults and children, with results comparable to the open procedure. In comparison the conventional laparoscopic procedure is little cost-intensive and therefore widely used. The available literature has to be analysed to find advantages for the cost-intensive, robot-assisted laparoscopic pyeloplasty from which patients can profit.

Abstract
Open pyeloplasty is still the gold standard in the treatment of ureteropelvic junction (UPJ) obstructions in many clinics. Similar functional results could be shown in diverse publications using conventional laparoscopic pyeloplasty (CLPP). The reconstruction of the UPJ is the main step during this type of surgery and constitutes a major challenge to surgeons working with minimally invasive techniques. The more complex the surgery the more obvious the benefits of robotic assistance (seven grades of freedom, 3D view etc.) in comparison to conventional laparoscopy. Thus robotic assistance is optimally suitable for pyeloplasty. The robotic-assisted laparoscopic pyeloplasty (RLPP) facilitates intracorporeal suturing and shortens the learning curve. Residents benefit from this shortened learning curve. Disorders caused by the non-physiological position during conventional laparoscopy are avoided during RLPP, which is an additionally benefit. Robotics also seem to be the optimum platform for the future of reconstructive LESS. The RLPP rather than the CLPP technique has therefore the potential to replace open pyeloplasty as the gold standard in treatment of UPJ.

Abstract
This retrospective clinical study presents pyeloplasty results following a muscle-splitting dissection, with mini-flank incision, using instruments held in a vertical position. Between 2004 and 2010, dismembered pyeloplasty (Anderson-Hynes) was performed in 37 cases (32 males and 5 females) with an average age of 26 years (range, 20-56 years). The technique was carried out through a window opened by separating the lateral abdominal muscles. Operation duration, length of incision, postoperative pain, complications, and radiological and clinical results were discussed. The operation duration was between 50 and 90 minutes (average=65 minutes), the incisional length 5 and 7 cm (average=5.2 cm), and visual pain scale was 4.1 ± 3.1 and 3.3 ± 3.4 at 4 and 24 hours after the operation, respectively. The duration of hospitalization was between 30 and 120 hours (average=42 hours). In a retrospective analysis of our study, one case was reoperated on, following recurrence with obstruction, there were 9 cases with prolonged dilation in response to diuretics and 29 cases with complete recovery. Pyeloplasty operations, with a vertical surgical approach through smaller incisions and muscle separation, offered shorter periods of hospitalization, less postoperative pain, acceptable cosmetic results and higher rates of functional recovery.

Abstract
BACKGROUND AND PURPOSE The gold standard for management of adult ureteropelvic junction obstruction is laparoscopic dismembered pyeloplasty (LPP), described by Anderson-Hynes, with reduced postoperative complications, early patient release, and favorable results. LPP, however, necessitates a high level of surgical expertise, especially with regard to reanastomosis. Knotless self-anchoring barbed sutures have also been introduced into aesthetic surgery and wound closure. We compared a self-retaining suture (SRS) Quill(®) (Angiotech, Canada) with a standard monofilament suture to further investigate their biomechanical and urodynamic aspects. MATERIALS AND METHODS We analyzed breaking strength and stiffness between SRS 4.0, 3.0, and polydioxanone suture (PDS(®)) 4.0 (Ethicon, Germany) using a biomechanical testing unit. Urodynamic evaluations were performed in the porcine upper urinary tract, closing a longitudinal incision either with SRS 4.0 (without knots) or with PDS 4.0 (five knots each end). Suture line shortening, suture time, tightness, and intrapelvic pressure were measured. RESULTS SRS 4.0 breaks at a mean of 11.57 N (standard deviation [SD]=1.25, stiffness 172.8 N/mm(2), SD=10.84), SRS 3.0 at 16.01 N (1.81), and PDS 4.0 at 18.41 N (0.75, 128.9 N/mm(2), 7.45). SRS 4.0 results in a suture line shortening from mean 3.08 to 2.26 mm (-26.6%) while PDS 4.0 shortens from 3.05 to 1.81 mm (-40.7%). The maximum intrapelvic pressure demonstrated no difference, and leakage was seen in 50% of the cases. Suture time was significantly decreased with SRS use (SRS 4.0 277 s and PDS 4.0 364 s). CONCLUSION SRS offers immediate tissue adaption with reduced suture line shortening and equal tightness compared with nonbarbed material in vitro. Knotless suturing using SRS is time efficient and appears to be an excellent material for LPP.

Abstract
PURPOSE Open dismembered pyeloplasty is usually performed through flank, anterior subcostal or posterior lumbotomy incisions. These incisions are cosmetically less acceptable and may produce significant postoperative pain. We present the smallest incision for open pyeloplasty, called a 'miniature pyeloplasty'. The aim of this study was to reduce hospital stay and postoperative pain, along with enhanced cosmetic results. PATIENTS AND METHOD 373 infants (mean age 4 months) with hugely dilated pelvises underwent the miniature pyeloplasty. The exact site of incision was determined by intraoperative renal ultrasonography and palpation. A muscle-splitting incision was made in the most dependent part of the lower quadrant. After meticulous dissection of the ureteropelvic junction component, the affected section was pulled out and underwent classic dismembered pyeloplasty without renal pelvis reduction. All children had long-duration stented anastomoses. Surgical incision size, operative time, hospital stay, postoperative analgesic use and complication rate were recorded. RESULTS The operation was successful in all patients. The mean operative time was 53 min (range 43-75) and patients were discharged after 18 ± 3 (mean ± SD) h. Incision size ranged from 11 to 15 mm (mean 13). No narcotic analgesic was required postoperatively and there were no major complications during follow up. CONCLUSIONS Miniature pyeloplasty is a safe and successful technique for ureteropelvic junction obstruction that avoids long operative time with negligible postoperative pain compared to the classic open pyeloplasty in infants. The exact incision site must be reconfirmed intraoperatively by physical examination or renal ultrasonography.

Abstract
PURPOSE OF REVIEW Despite increasing laparoscopic expertise in reconstructive surgery, open procedures still represent the gold standard. Robot-assisted techniques increasingly replace laparoscopy. However, laparoscopy is also developing: by improvement of ergonomics, new instruments, and techniques further reducing access trauma. We evaluated the actual role of laparoscopy focusing on main indications of urologic reconstructive surgery. RECENT FINDINGS We analysed the current literature (PubMed/Medline) concerning indications, perioperative results, complications, and long-term outcome of laparoscopy for pyeloplasty, ureteral reimplantation, stone surgery, management of vesico-vaginal fistula, sacrocolpopexy (including evidence level). For all indications, laparoscopy provides the advantages of less postoperative pain, blood loss, shorter convalescence, and minimal disfigurement. However, it requires expertise with endoscopic suturing. Most experience (N > 1000) exists with laparoscopic pyeloplasty and sacrocolpopexy which can be considered as valuable options (IIB). Concerning ureteral reimplantation and repair of vesico-vaginal fistula, only a limited number of cases were reported (N < 150) (III). Laparoscopic stone surgery may gain importance particularly in developing countries. Robot-assistance will definitively increase the application of laparoscopic techniques providing optimal ergonomics, whereas the role of single-port surgery will be limited. SUMMARY Laparoscopy will increasingly be used for reconstructive urologic surgery. This trend will be supported by the widespread use of the DaVinci device.

Abstract
BACKGROUND AND PURPOSE Robot-assisted pyeloplasty (RAP) has been established recently as an option in the management of ureteropelvic junction obstruction (UPJO). We present the first Canadian experience with RAP with respect to operative results and outcomes. We compare the surgical outcomes between experienced and trainee surgeons, with respect to operating room times and success rates. PATIENTS AND METHODS Eighty-eight patients underwent transperitoneal RAP for UPJO using the da Vinci robotic platform. Two surgeons performed Anderson-Hynes dismembered pyeloplasty in 85 cases and YV-plasty in 5 cases. Five patients had RAP for secondary UPJO after failure of other treatments. Diuretic renography was performed at 6 weeks, and 6, 12, 18, 24, and 36 months postpyeloplasty. The mean follow-up was 14.1 ± 8.5 months. RESULTS The mean operative time was 167.7 ± 43.2 minutes, and the mean anastomotic time was 41.9 ± 14.1 minutes. The mean operative duration significantly decreased with time (P < 0.05). Ten patients needed simultaneous nephroscopic stone management via the pyelotomy incision. The mean blood loss was 56.6 ± 55.4 mL, and the mean hospital stay was 2.5 ± 0.5 days. There were five major postoperative (stent migration, urinoma) and three minor complications that were associated with the RAP procedures. Postoperative renal scintigraphy demonstrated only four cases with persistent obstruction. Eighty-three (94.3%) patients experienced improvement of symptoms whereas 5 continued to be symptomatic. Two patients needed secondary procedures to relieve persisting obstruction. There were no statistical differences in outcomes between the experienced surgeons and trainees (P = 0.28). CONCLUSIONS In the first large case series of RAP from Canada, we demonstrate that RAP can be performed with relatively short operative times and is safe and effective, achieving similar long-term results with standard open repair. We show that robot-assisted surgery can be safely transitioned to surgical trainees. With its cost and availability, its role in the Canadian system needs further study.

Abstract
The aim of this review is to critically compare the different procedures performed for the treatment of ureteropelvic junction obstruction (UPJO) in order to identify, currently, the best treatment that a urologist should propose to patients with this condition. Three different types of procedures were assessed: open pyeloplasty (OP), endopyelotomy, and laparoscopic pyeloplasty (LP). Regarding efficacy, success rates of 94.1, 62-83, and 95.9-97.2% were reported for OP, endopyelotomy, and LP, respectively. Concerning operative time and length of hospital stay, no extensive data are available in the literature, although endopyelotomy seems to provide shorter times with respect to those reported after OP and LP. Regarding the complication rate, it was very similar after the different techniques and due to the respective approaches. Overall, our data support the conclusion that LP provided a balance between the highly successful technique reported by OP and the quick postoperative recovery provided by the endoscopic approach. Anyway, in spite of these clear advantages, the reproducibility of LP is still strongly limited by the challenge of the learning curve. The da Vinci robot (Intuitive Surgical, Inc., Sunnyvale, CA), providing an extraordinary vision and precision of surgical movement, appears to be changing this scenario, allowing naïve surgeons to achieve very good results after few procedures. In this setting, robot-assisted pyeloplasty seems to be emerging as the new standard of care in the patients with UPJO, which will further take place over the other techniques once its costs decrease.

Abstract
OBJECTIVES A retrospective study was performed to compare the results of laparoscopic pyeloplasty and antegrade endopyelotomy and complications observed after the two procedures. MATERIALS AND METHODS Seventy-five endopyelotomies and 90 laparoscopic pyeloplasties in patients with primary ureteropelvic junction obstruction (UPJO) were performed. The diagnosis of UPJO was based on a complete medical history, ultrasonography, urography (IVU), and/or diuretic renography. In 52 cases, a Whitaker test was performed before endopyelotomy. The mean follow-up was 31 months in the endopyelotomy group and 28.5 months in the laparoscopy group. Complete success was defined as absence of any clinical symptoms combined with significant reduction of hydronephrosis on diuretic IVU and ultrasonography, and no sign of obstruction on diuretic IVU, diuretic renography, or Whitaker test. RESULTS Complete success was observed in 55.4% of patients after endopyelotomy and in 95.3% of patients after laparoscopic pyeloplasty. In patients with primary UPJO, laparoscopic procedures yield better therapeutic results than endopyelotomy, irrespective of the degree of hydronephrosis. The number of complications after the two procedures was comparable with the exception of intraoperative bleeding, which was more frequent in the case of endopyelotomy. CONCLUSIONS Laparoscopic pyeloplasty should be the procedure of choice in the treatment of primary UPJO.

Abstract
PURPOSE We introduced a multimodal training program for laparoscopic pyeloplasty (LP) and evaluated its safety, feasibility, and efficacy. METHODS The program consisted of box-trainer training, animal-model training, and operative training. Five trainees with different experiences in open pyeloplasty and laparoscopy were exposed to the program. The mentor performed objective and subjective evaluations at each stage to ensure the training quality and operation safety. The perioperative parameters of five groups of patients who underwent LP by the trainees independently were evaluated. RESULTS All trainees successfully finished the training program and independently performed five LPs under the supervision of the mentor. Five trainees spent different training times on the box-trainer and animal-model training,but acquired similar laparoscopic proficiency. There were no conversions to open procedures, transfusions, or deaths among the patients. No statistically significant difference was found in the operative time, estimated blood loss, postoperative hospital stay, and perioperative complications among the five trainees (P > 0.05). CONCLUSION The multimodal training program can be used to train residents to perform advanced LP through step-by-step training from box trainer to animal model to clinical practice. The mentor-initiated approach is important to guarantee the training quality and safety.
