Abstract
Vascular (VH) according to Hellstrom-Chapman technique is considered a safe and effective alternative approach to pure extrinsic Ureteropelvic Junction Obstruction (UPJO) with good results in short and medium term, but few data are available on long and verylong term outcomes. Our aim is to evaluate VH long and very-long term outcomes in patients treated in pediatric age focusing on relapse, development of hypertension and/or inferior polar kidney hypotrophy during puberty and adulthood. From 1990 to 2015 in our Department 76 children were treated by open or laparoscopic VH for pure extrinsic-UPJO. We were able to contact 54 of 76. 41 patients (25 males, 16 females) accepted to be studied. Mean follow- up time was 12.7 years (range 6-27 years); mean age at the assessment was 22.2 years. We excluded patients who were younger than 13 (if females) or 14 (if males) at the assessment (upper limits of physiological puberty onset). Patients were followed with US, MAG-3-scan and arterial blood pressure measurement. Collected data were compared with the preoperative ones by Student t-test. 95% of US images and MAG-3-scan reports were compatible with complete resolution of obstruction with good renal functionality. 87% of patients were completely healthy. We recorded 3 cases of hypertension (7%) not secondary to renovascular origin; 2 cases with recurrent flank pain (5%) with slightly dilated pelvis at the US and sub-obstructive pattern at MAG-3-scan with preserved renal function. Our experience confirms that VH, (open/laparoscopic) is a safe and effective procedure with good outcomes at very longterm follow-up. No patients at puberty and in adulthood required reoperation or presented polar hypotrophy and related vascular hypertension. VH is an alternative approach to pure extrinsic-UPJO. There were few data about long and very-long term outcomes in patients after this kind of surgery. We followed-up 41 patients confirming that VH (open/laparoscopic) is safe and effective with good long-term outcomes.

Minimally invasive vascular hitch to treat pediatric extrinsic ureteropelvic junction obstruction by crossing polar vessels: A systematic review and meta-analysis. J Pediatr Urol 2021; 17:493-501. [PMID: 33775572 DOI: 10.1016/j.jpurol.2021.03.002] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/24/2020] [Revised: 02/12/2021] [Accepted: 03/04/2021] [Indexed: 01/08/2023]
Abstract
INTRODUCTION Vascular hitch (VH) gained an increasing success in treating ureteropelvic junction obstruction (UPJO) by crossing vessels (CV) in pediatrics. AIMS OF THE STUDY We aimed: (i) to compare laparoscopic VH versus laparoscopic dismembered pyeloplasty (DP) to treat UPJO by CV; (ii) to review possible amelioration given by a robot-assisted procedure. METHODS Using defined search strategy, three investigators identified all studies on laparoscopic VH. Those studies comparing VH versus DP or versus robot-assisted VH were included in the meta-analysis. The meta-analysis was conducted using RevMan 5.3. Data are mean ± SD. RESULTS Systematic review - Of 2783 titles/abstracts screened, 43 full-text articles were analyzed. Twelve studies on laparoscopic VH (298 pts) reported 98.3% success rate, with 1.3% intra-operative complications. Meta-Analysis - Five studies compared laparoscopic VH versus laparoscopic DP (277 pts). Operative time was reduced in VH (102.5 ± 47.5min) compared to DP (165.7 ± 53.7min; p < 0.00001). Complications were similar (VH 4/119 pts, 3.4 ± 1.2% versus DP 15/158 pts, 9.5 ± 6.8%; p = ns). Hospital stay was shortened in VH (1.1 ± 0.9dd) versus DP (3.3 ± 3.2dd; p < 0.0001; Summary Figure). The success rate was comparable (VH 115/118 pts, 97.5 ± 1.6% versus DP 157/158 pts, 99.4 ± 0.5%; p = ns). Two prospective studies compared robot-assisted VH to laparoscopic VH (53 pts). No differences were found among complications (robot-assisted VH 0/13 pts, 0% versus laparoscopic VH 1/40 pts, 2.5%; p = ns) and success rate (robot-assisted VH 13/13 pts, 100% versus laparoscopic VH 39/40 pts, 97.5%; p = ns). DISCUSSION Several studies have been reported long-term results of laparoscopic VH in children. However, few papers demonstrated its superiority over laparoscopic DP to treat extrinsic UPJO. In the present study, we found similar incidence of complications and success rates when comparing VH versus DP. Nonetheless, the operative time and the length of hospital stay were significantly reduced in VH compared to DP. An increasing number of surgeons performed robotic-assisted VH, reporting promising outcomes. However, only a couple of studies compared robot-assisted VH to laparoscopic VH, with a similar incidence of complications and success rate in both procedures. The main limitations of the study were related to the slight number of papers included and to their quality, since all of them were retrospective studies or prospectively followed-up cohort of patients. CONCLUSIONS Laparoscopic VH seems to be a safe and reliable procedure to treat UPJO by CV. The procedure appeared quicker than laparoscopic DP, with shortened hospital stay. Further studies are needed to corroborate these results and to establish amelioration given by a robot-assisted procedure.

Vascular hitch for paediatric pelvi-ureteric junction obstruction with crossing vessels: institutional analysis and systematic review with meta-analysis. BJU Int 2021; 129:679-687. [PMID: 33463000 DOI: 10.1111/bju.15342] [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: 11/14/2020] [Revised: 01/05/2021] [Accepted: 01/14/2021] [Indexed: 11/28/2022]
Abstract
OBJECTIVE To compare the outcomes for laparoscopic vascular hitch (VH) and dismembered pyeloplasty in patients with pelvi-ureteric junction obstruction (PUJO) secondary to crossing vessels (CV). PATIENTS AND METHODS Patients who underwent laparoscopic management of CV at our institution were identified between 2008 and 2020. Baseline characteristics and outcome measures were compared between those who underwent VH and those who underwent dismembered pyeloplasty. Those who underwent VH were selected intraoperatively by identifying CV in the absence of intrinsic obstruction by assessing resolution of hydronephrosis after cranially displacing the CV away from the PUJ, followed by intraoperative fluid bolus and diuretic test. In addition, a systematic search and meta-analysis were performed in June 2020 (International Prospective Register of Systematic Reviews [PROSPERO] ID CRD42020195833). RESULTS A total of 20 patients underwent VH and 74 dismembered pyeloplasty. On multivariate analysis, VH was associated with: shorter operative time (P = 0.001; odds ratio [OR] 0.455, 95% confidence interval [CI] 0.294-0.705) and length of stay (P = 0.012; OR 0.383, 95% CI 0.183-0.803), lower use of stents (P < 0.001; OR 0.024, 95% CI 0.004-0.141) and opioid administration (P = 0.005; OR 0.157, 95% CI 0.044-0.567). From our literature search, 194 records were identified and 18 records were included (three comparative and 16 non-comparative). Meta-analysis of the comparative studies and our institutional data showed similar success rates (relative risk [RR] 1.77, 95% CI 0.33-9.52) and complication rates (RR 0.75, 95% CI 0.20-2.82). VH was associated with shorter operative time (standardised mean difference [SMD] -1.65, 95% CI -2.58 to -0.72 h) and hospital stay (SMD -1.41, 95% CI -2.36 to -0.47 days). The VH success rates ranged from 87.5% to 100% in the identified studies. Failure of VH was associated with unrecognised concomitant intrinsic obstruction in addition to CV. CONCLUSIONS A VH, for well-selected patients with CV without concomitant intrinsic obstruction, offers a high success rate with shorter operative times.

Learning curve or experience-related outcome: what really matters in paediatric laparoscopic pyeloplasty. Wideochir Inne Tech Maloinwazyjne 2019; 15:377-381. [PMID: 32489500 PMCID: PMC7233165 DOI: 10.5114/wiitm.2019.89391] [Citation(s) in RCA: 4] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/20/2019] [Accepted: 10/04/2019] [Indexed: 12/02/2022] Open
Abstract
Introduction The process of improving one’s skills over time is called a “learning curve”. This term has attracted great attention during the last decades, especially in relation to laparoscopic techniques. Aim To assess the outcome of paediatric laparoscopic pyeloplasty (LP). Material and methods Retrospective analysis of the consecutive LPs. The inclusion criteria: (1) children aged < 18 years, (2) transperitoneal approach, and (3) the same operating paediatric urologist (RC). Patients with a history of any procedure on the upper urinary tract were excluded. Any surgical reintervention during follow-up was defined as a failure. The outcomes of LPs performed before 2012 (G1) were compared to those conducted between 2012 and 2016 (G2). Fisher’s exact test was used for statistical analysis. Results Ninety patients met the inclusion criteria, and a total of 95 LPs were performed. The mean operation time was 155 min, and the mean hospitalisation period was 2.4 days. In G1, 19 patients underwent Anderson-Hynes LP, 16 had Fenger non-dismembered LP and two underwent vascular hitch. In G2, 54, 2 and 2 patients underwent these procedures, respectively. The overall success rate was 91.5%. There were six failures in G1 and three in G2 (p = 0.147). Of the Anderson-Hynes LPs, 1/19 in G1 and 3/58 in G2 required reintervention (p = 1). For Fenger LPs, this was 4/16 and 0/2, respectively (p = 1). Only one patient required reoperation after vascular hitch. Conclusions The surgeons’ learning curve reflects their experience with regard to the entire therapeutic process, but not exclusively their manual skills.

Surgical validation of functional magnetic resonance urography in the study of ureteropelvic junction obstruction in a pediatric cohort. J Pediatr Urol 2019; 15:168-175.

Abstract
INTRODUCTION Ureteropelvic junction obstruction (UPJO) is one of the most common urological diseases in children. The etiology can be intrinsic, extrinsic (crossing vessel [CV] or adhesions), or mixed. To date, ultrasonography and scintigraphy are considered gold-standard imaging techniques for the study of UPJO. Functional magnetic resonance urography (fMRU) combines anatomical and functional information and has been recently evaluated for the detection of CVs in UPJO. OBJECTIVE The objective of the study was to evaluate the concordance between fMRU and surgery in determining the etiology of UPJO and the presence of obstructing/non-obstructing CVs. STUDY DESIGN Patients with unilateral hydronephrosis who underwent surgery after an fMRU were included in the sample. Surgical data regarding the etiology of UPJO were compared with radiological results. The etiology was divided into intrinsic, extrinsic due to CV, extrinsic due to adhesions, and mixed or cicatricial (postoperative). The concordance was calculated by means of the Cohen's kappa coefficient. RESULTS The observed agreement between fMRU and surgical findings regarding the etiology and the presence of CV were 83.2% and 89.4%, respectively (with substantial Cohen's kappa coefficient). The sensitivity and specificity of fMRU were 0.84 and 0.93, respectively; the positive predictive value (PPV) and negative predictive value (NPV) were 0.889 and 0.897, respectively. The observed agreement regarding the type of vessel was 88.3% with a Cohen's kappa coefficient of 0.787 (substantial). DISCUSSION In children with hydronephrosis, it is very important for the surgeon to quantify the extent of dilation, define the etiology of the obstruction, and the presence or absence of CVs. fMRU is a 'one-stop-shop' technique which provides both anatomical and functional information showing a high concordance with surgical findings, avoiding radiation exposure. CONCLUSIONS fMRU should be considered a valid imaging technique in the study of pediatric UPJO, as it provides the surgeon with important information regarding the etiology of the obstruction for the preoperative planning.
