Abstract
Detailed extraparenhymal renal hilar dissection was performed on 110 fixed cadaveric kidneys (60 from male cadavers and 50 from female cadavers). We analyzed the number of renal arteries, angles between renal arteries and abdominal aorta, length and diameter of the renal arteries. Multiple renal arteries were present in 20.9% of cases, with a slightly higher incidence on the right side (21.8%: 20.0%). The angle between the aorta and the RRA varied from 30° to 100° with a mean of 64.1°, while the angle between the abdominal aorta and the LRA was 40° to 115°, with a mean of 67.3°. The external caliber of the RRA at the point of origin from the abdominal aorta was 5 mm to 9.1 mm, with a mean of 6.8 mm. The same caliber of the LRA was 3.7 to 9.6 mm with a mean of 7.0 mm. The average length of the renal artery from the point of origin from the abdominal aorta to the branching point was 36.2 mm for the right renal artery and 30.7 mm for the left renal artery. The average length of the renal artery from the point of origin from the abdominal aorta to the renal hilum was 65.1 mm for the right one and 54.7 mm for the left one. Knowledge of the number of renal arteries, their mode of entry into the kidney, the angles they build with the abdominal aorta, their diameter and length has practical applications in interventional radiology and surgery of the kidney and its environment.

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
OBJECTIVE It was intended to demonstrate the update report of our experience with laparoscopic management of ureteropelvic junction obstruction by division of the aberrant vein and cephalad relocation of the crossing artery in a large group of patients with long-term follow-up. PATIENTS AND METHODS Three hundred and twenty-nine patients were candidate to undergo laparoscopic transperitoneal ureteropelvic junction obstruction management from June 2001 to March 2009. Intraoperatively, lower pole crossing vessels were identified in 117 patients (35.5%). After division of the aberrant vein, the crossing artery was relocated cephalad and fixed to peripelvic tissue. Renal pelvic emptying with proper pyeloureteral peristalsis was considered in 71 patients, so neither pyeloplasty nor Double-J stent was fixed for them. Postoperative outcomes were assessed with intravenous urography and/or diethylene triamine pentaacetic acid-diuretic renal scan. RESULTS Of the 71 patients who underwent this laparoscopic approach, 42 were completely followed over a long-term period. The mean age of patients was 27 (7-69) years. The mean operative duration was 133 (55-185) minutes and blood loss was negligible. The mean hospital stay was 2.8 (1-7) days and mean follow-up was 29 (3-84) months. Overall success rate was 90% and recurrence of obstruction was noted in two patients. No significant complications were observed. CONCLUSION Cephalad relocation of the lower pole crossing artery after division of the crossing vein in selected cases could be an ideal alternative for dismembered pyeloplasty with noticeable outcomes in long-term follow-up.

Abstract
AIMS The standard treatment for pelviureteric junction obstruction (PUJO) has been dismembered pyeloplasty. The open surgical, Hellström procedure in which crossing polar vessels are relocated, has been an option in adult urological practice. We present our experience with laparoscopic vascular relocation in children. METHODS Data were retrospectively gathered on all patients who underwent laparoscopic relocation of lower pole vessels (LRLPV) at our institution between July 2004 and March 2008. Follow-up ultrasounds and MAG3 were obtained. RESULTS LRLPV was performed in 10 boys and 9 girls. Patients were between 5.8 and 15.25 years (median 9.9 years). They presented with recurrent abdominal pain (n = 17), urinary tract infections (n = 7) and haematuria (n = 3). On ultrasound, MAG3 and retrograde studies they had hydronephrosis, obstructed drainage and a normal calibre ureter with a sharp cut-off. They were further assessed at laparoscopy and were found to have aberrant lower pole crossing vessels. All underwent laparoscopic mobilization of the lower pole vessels from the region of the PUJ thereby freeing the junction and relocating them superiorly onto the anterior wall of the pelvis. The median operating time was 120 min (range 60-240 min). The median hospital stay was 2 days (range 1-3 days). They were followed up for a median period of 12 months (range 6-36 months). All patients have remained asymptomatic. Ultrasound done at 6 months showed decreased hydronephrosis. MAG3 study showed improved drainage in 17, while 1 had poor drainage. This patient remains symptom free and is under regular follow up. CONCLUSION Laparoscopic vascular relocation is an unconventional technique in carefully selected patients with PUJO. It obviates disrupting an intrinsically normal PU junction and treats the cause rather than the effect. Our intermediate-term results are encouraging and further long-term assessment is needed.

Abstract
OBJECTIVE Ureteropelvic junction obstruction (UPJ) can be caused by intrinsic disorganization or extrinsic compression from crossing vessels (CV). What is not clear is whether there is also intrinsic UPJ pathology in patients with CV. Recent surgeries, such as the Hellström vascular hitch procedure, move the CV cephalad without resecting the UPJ, which presumes no intrinsic narrowing. Our aim was to determine whether the histologic features of the 2 types of UPJ obstruction are distinct enough to enable a blinded pathologist to histologically identify the cause of obstruction. METHODS We reviewed all patients undergoing pyeloplasties from 2000 to 2006. All CV cases with available pathology were selected. A random selection of intrinsic cases was used as controls. One blinded pathologist reviewed the histology, specifically scoring muscle and collagen density. RESULTS Sixteen patients were reviewed. Seven had CV and 9 had intrinsic obstruction. Muscle density was different between the 2 groups with CV denser compared with intrinsic (P = .005). The pathologist correctly assigned the cause of obstruction in 5/7 (71%) of CV and 7/9 (78%) of intrinsic cases (P = .039). CONCLUSIONS Identification of a significant CV intraoperatively does translate to a discernible appearance histologically.

Abstract
OBJECTIVE To demonstrate the role of the laparoscopic approach for management of primary ureteropelvic junction obstruction (UPJO) using two different techniques in the pediatric age group. MATERIAL AND METHODS From April 2005 to October 2008, 63 pediatric patients underwent treatment of primary UPJO via a laparoscopic approach. Dismembered pyeloplasty was elected in 56 renal units while nine patients were managed by upward transposition of accessory renal artery after division of accessory renal vein. No JJ stent was required in these nine patients. RESULTS Mean age of patients was 61 (2-180) months. Mean operative time was significantly lower in those managed by transposition of aberrant vessels compared with dismembered pyeloplasty. The mean hospital stay was 6.4 (2-14) days for the dismembered technique and 2.1 (1-4) days for the vascular transposition approach. Significant improvement of obstruction was achieved in all of the patients who underwent the modified Hellstrom technique and in 92.81% of the renal units undergoing dismembered pyeloplasty. CONCLUSION The technique of laparoscopic transposition of crossing renal artery without violating collecting system may have a role in minimally invasive management of UPJO in selected pediatric patients. Further research with larger samples and a longer follow-up period is required.

Abstract
PURPOSE To evaluate the results of a sequence of 47 laparoscopic Anderson-Hynes pyeloplasties for the treatment of patients with ureteropelvic junction obstruction, independently of the etiology. MATERIALS AND METHODS Twenty male and 27 female patients diagnosed with ureteropelvic junction obstruction were treated by Anderson-Hynes transperitoneal laparoscopic dismembered pyeloplasty from April 2002 to January 2006. The age of the patients ranged from four to 75 years, with a mean age of 32.3 years. The follow-up ranged between six and 30 months, with a mean follow-up time of 24 months. The outcomes were evaluated through the assessment of symptoms and imaging studies. RESULTS In 44 (93.6%) of the 47 patients, resolution of the pain and a reduction in ureteropelvic dilation were observed. The mean operative time was 157 minutes (ranging from 90 to 270 minutes). Neither blood transfusion nor conversion to open surgery was required. The mean hospital stay was 2.2 days. The presence of crossing vessels over the ureteropelvic junction was verified in 26 patients (55%), and vessel transposition in relation to the urinary tract was performed in 25 of these cases. In one patient, the crossing vessel was mobilized out of the ureteropelvic junction with a perivascular suture to the renal capsule associated with the pyeloplasty. CONCLUSIONS The outcome of transperitoneal Anderson-Hynes laparoscopic pyeloplasty used for different causes of pyeloureteral obstruction presented a success rate similar to a previously-published open procedure, with the advantage of being less invasive. This procedure may be considered the first option for the treatment of ureteropelvic junction obstruction.
