Laparoscopic pyeloplasty: the updated McMaster University experience

Objective: The open Anderson–Hynes procedure has an overall success rate of 90% for ureteropelvic junction obstruction. Laparoscopic pyeloplasty (LP) was developed to reduce morbidity and hospital stay while preserving the excellent results. We report on the results of our experience with laparoscopic pyeloplasty.Methods: Between January 2001 and May 2006, 77 consecutive patients underwent LP performed by one of 4 surgeons at our institution. Patients were reassessed with ultrasound (U/S) or intravenous pyelogram (IVP) at 6 weeks. Diuretic renal scan and U/S or IVP were performed at 6 months, and subsequent follow-up included a U/S or IVP as well as clinical assessment. Patients were assessed for pain and hydronephrosis on radiologic imaging, clearance on diuretic renal scan (T1/2) and differential renal function.Results: We evaluated 73 patients. The mean patient age was 38 years (range 16–71 yr), the mean operating time was 218 minutes (range 110–409 min), and the mean blood loss was 57 mL (range 25–250 mL). Mean hospital stay was 3.0 days (range 2–7 d). The success rate was 90.4%, and failures were mainly due to poor function after surgery (3 patients). Pyelolithotomy was performed concomitantly on 6 patients, which on average extended operative time by 36 minutes.Conclusion: Our success rates are consistent with the LP experience of other centres and are comparable with rates for the open technique. Patients had short hospital stays, and complications were negligible. With experienced surgeons, LP should be the first-line treatment for ureteropelvic junction obstruction.

Objective: The aim of the objective was to present our initial experience and evaluate the feasibility of the novel comprehensive modified laparoscopic pyeloplasty (CMLP) technique based on membrane anatomy. Materials and Methods: Forty-eight patients underwent CMLP from February 2016 to October 2020. CMLP involves the following: dissection of the ureter was based on the fascia or fusion fascia formed by embryonic development. The ureter was separated from the ureteral sheath, and the pelvis and ureter were incised with incomplete amputation. The first stitch was placed between the lower point of the spatulated ureter and the lowest corner of the renal pelvis to ensure correct orientation of the anastomosis; anastomosis of the renal pelvis and ureter was performed using the touchless technique. Results: All CMLPs were completed successfully without conversion. The mean overall operating time was 230.96 min. The median estimated blood loss was 50.00 (interquartile range 20.00–57.50) mL. The average postoperative hospital stay was 9.31 days. The average follow-up time was 24.73 months. No major complications occurred. In 1 case, revision laparoscopic pyeloplasty was performed, but the obstruction persisted after double J stent removal, so ultimately, the double J stent required regular replacement. Another asymptomatic patient with hydronephrosis experienced failed treatment and is still under follow-up. The overall success rate was 95.83% (46/48). The success rate in patients with recurrent ureteropelvic junction obstruction (UPJO) was 87.5% (7/8). Conclusions: CMLP is a practical and effective treatment option for UPJO with a high success rate. An advantage of CMLP is the clear surgical field.

Open Pyeloplasty

INTRODUCTION Over the last 20 years, the surgical management of ureteropelvic junction obstruction (UPJO) has been revolutionised by the development of endourological instrumentation and several minimally invasive procedures including: antegrade or retrograde endopyelotomy, retrograde balloon dilatation, and laparoscopic pyeloplasty. Currently, in our department, we offer percutaneous antegrade endopyelotomy (PAE) as primary treatment of UPJO in adults, believing it offers less morbidity, better cosmetic results, and quicker operating time compared with open pyeloplasty. PATIENTS AND METHODS We performed a retrospective audit of our results for the 14 patients who underwent percutaneous antegrade endopyelotomy between January 2000 and May 2004. RESULTS Mean operative time was 53 min (range, 30–80 min), mean in-patient stay was 3.8 days (range, 2–7 days), and there were no major postoperative complications for this series with mean follow-up of 31.8 months (range, 12–52 months). Eleven out of the 14 patients (79%) showed radiological improvement on their 3-month MAG 3 (mercaptoacetyl-triglycyl) renogram, and 13 out of the 14 (93%) patients reported significant reduction or resolution of pain, compared with their preoperative state. CONCLUSIONS The majority of urologists still offer open pyeloplasty as primary treatment for UPJO with laparoscopic pyeloplasty currently an evolving procedure in the UK. Our series reports comparable success rates for PAE compared to other series. Despite these results, we feel that the future role of percutaneous endopyelotomy will be as a salvage procedure following failed open or laparoscopic surgery. However, in patients with concurrent stone disease or requiring antegrade ureteric access, percutaneous endopyelotomy would be suitable as a primary treatment option.

Open Pyeloplasty

Background: Historically open pyeloplasty has been regarded as the gold standard for the surgical management of ureteropelvic junction obstruction (UPJO). The treatment of this condition has evolved considerably over the past two decades resulting in new surgical approaches. One of these approaches is laparoscopic pyeloplasty,this technique aimed to achieve the same results as open surgery,with lower rates of morbidity and complications. Aim of the study: To compare the operative time,hospital stay,analgesic use,perioperative complications,and success rate between laparoscopic and open pyeloplasty in Al Diwaniya Teaching Hospital. Patients & Methods: From October 2014 to October 2016,40 patients (26 males and 14 females) with Ureteropelvic junction obstruction who had been admitted to the urology unit of Al Diwaniya Teaching Hospital were enrolled in this study. Their ages ranged from 10 to 44 years with a mean age of 24 years. The patients were selected on the basis of standard indications for PUJO repair. The patients were assigned into two groups. Twenty patients underwent transperitoneal laparoscopic pyeloplasty and 20 patients underwent open surgery. The choice between the two types of operation was selected according to surgeon's preference (only surgeon who has enough experience with laparoscopic surgeries perform laparoscopic pyeloplasty,while the other performed open surgery). Preoperative evaluations were done using abdominal ultrasound and IVP. Laboratory tests included urinalysis,urine culture,blood urea,and serum creatinine. Blood group was determined. We compared the operative time,complications rates,hospital stay and success rate of the two groups.Mean operative time was 2 hours and 3 hours in open and laparoscopic pyeloplasty groups,respectively. Mean hospital stay was shorter (24 hours) in the laparoscopic group and (48 hours) in open group. Mean follow-up period was 9 months. Postoperative complication rates were 20 % and 30 % in laparoscopic and open pyeloplasty groups,respectively. Success rates were 95% and 90 % for open and laparoscopic pyeloplasty groups,respectively. Repeated surgery was performed in 2 patients of laparoscopy and 1 of open pyeloplasty groups due to recurrence of stricture.The safety and efficacy of laparoscopic pyeloplasty is comparable to that of open pyeloplasty,with better cosmetic results and shorter hospital stay,therefore laparoscopic pyeloplasty can replace open surgery and may be considered the gold standard technique for the treatment of ureteropelvic junction obstruction in expert hands.

Introduction: We report our experience with laparoscopic management of ureteropelvic junction obstruction in horseshoe kidneys.Methods: Between February 2004 and March 2014, 15 patients with horseshoe kidneys and symptomatic ureteropelvic junction obstruction underwent laparoscopic management at our national referral centre. Depending on the anatomy and presence of obtrusive vessels or isthmus, we performed either dismembered, Scardino or Foley YV pyeloplasty, or Hellstrom vessel transposition. Patients were initially evaluated by ultrasonography, then diuretic scintiscan at 4 to 6 months, and followed by yearly clinical and sonographic exams.Results: This study included 11 male and 4 female patients between the ages of 4 to 51 year (average 17.7). The left kidney was involved in 12 patients (80%). Operation time was 129 minutes (range: 90–186), and patients were discharged within 2.8 days (range: 1–6). Although 8 (53.3%) patients had crossing vessels, of which 6 required transposing, the Hellstrom technique was solely used in 3 cases, of which notably 1 case failed to resolve and required laparoscopic Hynes within the next year. Eight cases underwent dismembered pyeloplasty, 2 Foley YV, 1 Scardino flap and 1 required isthmectomy and vessel suspension. At the mean follow-up of 60 (range: 18–120) months, the overall success rate was 93.3%.Conclusions: To our knowledge, this represents the largest report on laparoscopic pyeloplasty for horseshoe kidneys, providing the longest follow-up. Our findings confirm prior reports supporting laparoscopy and furthermore show that despite the prevalence of crossing vessels, transposition alone is seldom sufficient.

Introduction Surgery for ureteropelvic junction obstruction (UPJO) is performed by both pediatric surgeons (PS) and urologists (URO). The aim of this study was to analyze treatment modalities for UPJO and results in relation to the surgical technique and the operating discipline in Germany. Materials and Methods Data of patients aged 0 to 18 years were extracted from a major public health insurance (covering ∼5.7 million clients) during 2009 to 2016 and were analyzed for sociodemographic variables, surgical technique, and treating discipline. Logistic regression analysis was performed for the risk of a complication within the first postoperative year. Results A total of 229 children (31.0% female) were included. Laparoscopic pyeloplasty (LP) was performed in 58 (25.3%) patients (8.6 ± 6.4 years), and open pyeloplasty (OP) was applied in 171 (74.7%; 4.6 ± 5.9 years). LP was the dominant technique in females (p < 0.02); males preferentially underwent OP (p < 0.02). Length of hospital stay was 4.3 days (p = 0.0005) shorter in LP compared with that in OP, especially in children ≤ 2 years (6.7 days, p = 0.007). PS operated on 162 children (70.7%), and URO performed surgery on 67 patients (29.3%). The mean age of children operated by PS (3.5 ± 4.7 years) was significantly younger compared with that operated by URO (10.8 ± 6.5 years, p < 0.0001). Complication rates were independent of surgical technique or treating specialty. Conclusion In Germany, UPJO was treated by LP in 25.3% of patients, which was associated with a shorter length of stay, especially in children ≤ 2 years. Complication rates were independent of the operating specialty and surgical technique. Therefore, LP should be further promoted for the treatment of UPJO in small children.

Objective. Ureteropelvic junction obstruction (UPJO) is a common cause of symptomatic ureteral obstruction. The aim of this study is to assess the outcome of laparoscopic pyeloplasty in patients with UPJO. Patients and Methods. Medical reports of 47 UPJO patients treated with laparoscopic pyeloplasty were retrospectively analysed. All patients were recruited from our center in the period 2004–2011. Results. We evaluated 47 patients. Mean age was 36 years and mean hospital stay 3.6 days. 42 (79%) of the patients had pain and 46 (98%) were diagnosed with hydronephrosis. 19 patients (40%) had a renal function below 40% of the affected kidney and 49% had impaired renal scan drainage. Postoperative significant improvement in pain score and renal scan drainage was found in 92% and 47% of the patients, respectively. Improvement of renal function > 10% was found in 11 patients (23%); the function remained stable in 31 patients (66%) and deteriorated > 10% in 5 patients (11%). We found no correlation between sex or age and the outcome. Conclusion. Laparoscopic pyeloplasty for UPJO leads to relief of pain and preserved or improved renal function in the majority of the patients. Overall laparoscopic pyeloplasty is an efficient treatment for UPJO.

Purpose. To compare the operating time, amount of blood transfused, length of hospital stay, and early complications (within 6 months) between 2-week staged bilateral arthroplasties and matched randomised controls undergoing unilateral arthroplasties. Methods. From October 1992 to October 2000, 90 patients who underwent bilateral hip or knee arthroplasties with a 2-week interval were compared with matched randomised controls undergoing unilateral arthroplasties. A single surgeon performed all procedures. Results. After the match-up process, 30 pairs of patients were included in the analysis. There were no significant differences in the operating times, amount of blood transfused, and early complication rates. The mean difference in length of hospital stay was significant ( t= −3.552, df=29, p<0.001). Conclusion. Compared to staged procedures with an interval months apart, staged sequential arthroplasty with a 7- to 10-day interval during one hospital admission is more efficient, as it facilitates earlier rehabilitation without higher complication rates, and entails shorter hospital stays.

Abstract Background Multiple surgical treatment options are available for the treatment of ureteropelvic junction obstruction (UPJO). The aim of this study is to compare the most frequently used technics in a comprehensive network approach. Methods A systematic literature search of the EMBASE, MEDLINE and COCHRANE libraries was conducted in January 2018. Publications were included that evaluated at least two of the following surgical techniques: open pyeloplasty (OP), endopyelotomy (EP), laparoscopic (LP) and robot assisted pyeloplasty (RP). Main outcomes were operative success, complications, urinary leakage, re-operation, transfusion rate, operating time, and length of stay. Network meta-analyses with random effects models simultaneously assessed effectiveness of all surgical techniques. Results A total of 26 studies including 3143 patients were analyzed. Compared with RP, EP and LP showed lower operative success rates (EP: OR = 0.09, 95%CI:0.05–0.19; p < 0.001; LP: OR = 0.51, 95%CI:0.31–0.84; p = 0.008). Compared with OP, LP and RP had lower risk for complications (LP: OR = 0.62; 95%CI:0.41–0.95; p = 0.027; RP: OR = 0.41; 95%CI:0.22–0.79; p = 0.007). Compared with RP, no significant differences were detected for urinary leakage or re-operation, transfusion rates. Compared with EP, RP yielded longer operating time (mean = 102.87 min, 95%CI:41.79 min–163.95 min, p = < 0.001). Further significant differences in operating times were detected when comparing LP to EP (mean = 115.13 min, 95%CI:65.63 min–164.63 min, p = < 0.001) and OP to EP (mean = 91.96 min, 95%CI:32.33 min–151.58 min, p = 0.003). Conclusions Multiple surgical techniques are available for treatment of UPJO. RP has the highest rates of operative success and as well as LP lower complication rates than OP. Although surgical outcomes are worse for EP, its operating time is shorter than OP, RP, and LP. Surgeons should consider these findings when selecting the optimal treatment method for individual patients.
