RESUMO

Although the Boari flap technique is commonly described in the literature as a method for primarily distal and middle ureteral injuries, it can also be used for reconstructing the proximal segment of the ureter. In this case study, we present a patient who underwent gynecological surgery with subsequent damage to the proximal ureter, and who underwent ureteral reconstruction using methods such as kidney mobilization, Boari flap, and psoas hitch. The postoperative period was uncomplicated, and after a six-month follow-up, the reconstructed ureter is functioning well, and the patient is in good health.

RESUMO

Objective: To present an alternative technique called pseudo-flap for reconstructing long ureteral defects as an alternative to Boari flap. Despite being used for more than 70 years by urologists for tension-free reconstruction of distal and mid-ureteral defects, the Boari flap exhibits high complication rates, with an average of 27% (range 5.5%-30.4%). These complications arise from compromised blood supply, attributed to incisions made on all three sides of the flap and dependence on the flap base as the sole source of blood supply. Methods: We retrospectively reviewed patients who underwent our modified technique by a single surgeon between 2008 and 2021. We used a semi-oblique cystotomy on the lowest part of the anterior and contralateral aspects of the bladder after complete release from adhesions and sacrificing the superior vesical pedicle, if necessary. The innovative part of the technique involved making short relaxing incisions at different levels on both sides of a pseudo-flap while pushing the bladder dome upward to reach the healthy ureter in a tension-free manner, followed by anastomosis with a non-refluxing or refluxing technique. Results: Fifteen patients underwent the pseudo-flap technique with a mean follow-up of 16.9 months. Four had prior radiation, three had hyperthermic intraperitoneal chemotherapy (HIPEC) for peritoneal carcinomatosis, and one had a ureteral stricture in a transplanted kidney. Eight procedures were performed during intraoperative consultations.Only one patient (7%) developed a major complication (Clavien-Dindo grade ≥2). This patient developed postoperative leak, and none developed obstructive hydronephrosis, suggesting stricture or flap ischemia. The mean length of the flap was 9.3 cm. Conclusion: Our pseudo-flap technique has lower complication rates than the traditional Boari flap. It is not technically challenging, minimally compromises blood supply and is thus especially suitable for complex, highly morbid patients with decreased tissue vascularity, such as those with prior radiation and peritoneal carcinomatosis.

RESUMO

OBJECTIVES: The objective is to discover the etiopathogenesis of benign lower ureteric stricture in Eastern India and compare the outcome of open versus laparoscopic ureteroneocystostomy. MATERIALS AND METHODS: Retrospectively 52 patients who underwent laparoscopic (n = 28) or open ureteroneocystostomy (n = 24) for lower ureteral stricture between January 2018and December 2021 were included. The demography, aetiology, radiologic imaging, intraoperative & postoperative outcomes and follow-up data were collected and analysed. RESULTS: The mean duration of follow up was 14.3 months. Lower ureteric stricture were common in females. The most common cause of the stricture was iatrogenic injury (42%). Other causes were tuberculosis, post-endourological surgery, obstructing mega ureter, endometriosis and idiopathic. Laparoscopic surgery had longer mean operative time (228 vs 171 min), less blood loss (166 vs 246 ml), lower VAS score (6.1 vs 7.22) and less need of post-operative analgesia (1.86 vs 2.36 days). The hospital stay (5.36 vs 6.77 days) and post-operative complications (none vs 3) were also significantly lower in laparoscopic group. Open surgery and laparoscopic surgery had success rate of 100% and 96.6% each. CONCLUSIONS: Iatrogenic injury are the most common cause of ureteric stricture followed by tuberculosis. Laparoscopic approach is a feasible option in treatment of lower ureteric stricture as it offer comparable outcome to open procedure while offering the advantage of a minimal invasive technique. Stricture secondary to iatrogenic injury poses a different challenge due to presence of hard dense fibrosis. This is a complex reconstructive procedure and has a steep learning curve and demands high level of laparoscopic skill.

RESUMO

OBJECTIVE: To investigate the feasibility and the efficacy of laparoscopic ureteroneocystostomy with round ligament bladder hitching. METHODS: This is a monocentric retrospective study. Enrolled patients affected by deep endometriosis underwent laparoscopic nerve-sparing parametrectomy and monolateral ureteroneocystostomy with bladder suspension to the round ligament. Perioperative and postoperative outcomes were collected, as well as urinary and pain symptoms before and after surgery. RESULTS: Laparoscopic ureteroneocystostomy with round ligament bladder hitching was performed in nine women. The most frequent postoperative complication was post-voiding urinary retention (22.2%). No ureteral fistula or stenosis of the anastomosis was reported. CONCLUSION: In selected cases of ureteral resection and reimplantation, performing a round ligament bladder hitching allowed us to overcome the ureteral gap. This is a safe and feasible procedure to ensure stability of the anastomosis and avoid the possible disadvantages of the "standard" psoas hitch procedure.

RESUMO

STUDY OBJECTIVE: To investigate the short-term outcomes of laparoscopic ureteroneocystostomy in patients with ureteral endometriosis (UE). DESIGN: Retrospective cohort study of consecutive patients who underwent surgery for the ureter endometriosis with hydronephrosis. SETTING: A private hospital that provide primary, secondary and tertiary care. PATIENTS: 30 consecutive patients with UE who underwent laparoscopic ureteroneocystostomy at our institution between May 2008 and April 2020. INTERVENTIONS: Laparoscopic ureteroneocystostomy, if necessary, hysterectomy, salpingo-oophorectomy, cystectomy, partial bladder resection, or partial bowel resection were performed. MEASUREMENTS AND MAIN RESULTS: The most common chief complaint was pelvic pain (40%). Endometriosis affected only the left ureter in 56.7% of patients, only the right ureter in 33.3%, and both ureters in 6.7%. Involvement of the ipsilateral ovary was confirmed in 64.3%. The most frequent location of UE was 1-3 cm above the UVJ (46.7%). A psoas hitch was performed in 7 patients (23.3%), and the Boari flap was used in 9 patients (30%). Hysterectomy was performed in 12 patients (40%), and 6 of them had a concomitant bilateral salpingo-oophorectomy (20%). In addition, 3 patients (10%) underwent partial bowel resection, and 2 patients (6.7%) underwent partial bladder resection. After surgery, 24 of 27 patients (80.0%) were free of sever hydronephrosis after surgery. Hydronephrosis recurred in a single patient (3.3%), but the grade of hydronephrosis improved significantly after surgery (P < 0.001). At 6 months of follow up, 4 patients (13.3%) experienced urinary tract infections and 2 patients (6.7%) reported dysuria. Patients reported a regression of dysmenorrhea symptoms (P < 0.001). CONCLUSION: This study shows that ureteroneocystostomy provides good results in terms of relapses and symptom control in patients with ureteral endometriosis.

RESUMO

Purpose: Although robot-assisted laparoscopic ureter reimplantation (RALUR) is a recognized alternative to open and laparoscopic ureter reimplantation in treating distal ureteral obstruction, there are limited data on long-term efficacy and safety outcomes of non-antireflux RALUR. We assessed patients undergoing RALUR, evaluating operative, functional, and safety determinants. Materials and Methods: All consecutive patients undergoing non-antireflux RALUR between April 2015 and January 2020 were included in this retrospective cohort study. The primary outcome endpoint was recurrent distal ureteral obstruction. Results: Mean follow-up was 41.3 months (95% confidence interval, 33.3-49.2; range 2-82). Among the 26 included patients, none developed recurrent distal ureteral obstruction. Kidney function in terms of serum creatinine level (72.0 µmol/L vs 71.0 µmol/L, p = 0.988) and glomerular filtration rate (92.0 mL/min vs 91.0 mL/min, p = 0.831) was stable between the preoperative period and the last follow-up. Renal pelvis dilatation decreased significantly postoperatively, from grade 2 to grade 0 (p < 0.001). Most patients (73.1%) remained free from any clinical symptoms of reflux during the follow-up. No recurring urinary tract infections were reported. The rate of postoperative complications (Clavien-Dindo grade ≥II) was 23.1%. All complications resolved without sequelae. Conclusions: Non-antireflux RALUR appears to be safe and effective in the management of distal ureteral obstruction. There was no recurrent ureteral obstruction after RALUR in our cohort during a mean follow-up of more than 3 years. Non-antireflux reimplantation did not seem to have any notable impact on renal function during the follow-up period.

RESUMO

INTRODUCTION AND HYPOTHESIS: Describe the surgical technique of laparoscopic ureterovesical reimplantation applying the modified psoas hitch with Lich-Gregoire onlay technique to manage a distal ureteral fistula after a hysterectomy for a gynecologic malignancy. MATERIALS AND METHODS: This video illustrates the surgical technique of laparoscopic ureteral reimplantation applying the modified psoas hitch with Lich-Gregoire onlay technique in a ten-step surgical video. RESULTS: Step 1: closure of the caudal ureter.Step 2: Ureter mobilization. Step 3: Ureter spatulation. Step 4: Bladder mobilization. Step 5: Detrusor muscle incision. Step 6: Bladder suspension. Step 7: Mucosal incision. Step 8: Ureterovesical anastomosis. Step 9: JJ stent insertion. Step 10: Detrusor muscle closure. CONCLUSION: Intraoperative identification of ureteral injury and prompt repair are recommended. Ureteral repair technique depends on the ureteral injury site. Distal ureteral injuries (UIs) might require either uretero-ureterostomy or ureteral reimplant with or without a psoas hitch. The Lich-Gregoir is one of the two most frequently used anti-vesicoureteral reflux techniques and has acceptable complication rates.

RESUMO

Background: Aim of this study was to report a single-center experience with robot-assisted ureteral reimplantation (RAUR) and to compare its outcomes with those of open ureteral reimplantation (OUR). Materials and Methods: Patients who underwent RAUR or OUR for ureteral disease between 2016 and 2020 were identified. Data collected included baseline, pathologic, perioperative, and postoperative features. The RAUR outcomes were compared with those of OUR. Results: Overall, 21 (42.8%) patients underwent RAUR, and 28 (57.2%) underwent OUR. The two groups were similar in terms of baseline and pathologic characteristics. There was a statistically significant difference in favor of RAUR for median operative time (216 vs 317 minutes, p = 0.01) and median blood loss (35 vs 175 mL, p = 0.001). No difference was observed in overall complication rate (33.3% vs 46.4%, p = 0.9), as well as major complications (Clavien-Dindo≥III grade) rate between RAUR and OUR groups. Median length of stay was shorter for RAUR (2 vs 6 days; p = 0.001), as well as median catheterization time (16 vs 28 days; p = 0.005). Conclusions: RAUR is a safe and effective minimally invasive surgical procedure for the management of mid to distal ureteral strictures. It can recapitulate the success rate of the gold standard OUR while offering a benefit in terms of lower surgical morbidity and faster postoperative recovery.

RESUMO

OBJECTIVE: To describe step-by-step surgical techniques and report outcomes of the largest single-centre series of patients with distal ureteric disease exclusively treated with robot-assisted ureteric reimplantation with Boari flap (RABFUR) and psoas hitch (RAPHUR), with a minimum follow-up of 1 year and complete postoperative data. PATIENTS AND METHODS: A total of 37 patients with distal ureteric disease were treated between 2010 and 2018. Of these, 81% and 19% underwent RAPHUR and RABFUR, respectively. Intra-, peri- and postoperative outcomes were assessed. The 90-day postoperative complications were reported according to the standardised methodology proposed by the European Association of Urology Ad Hoc Panel. Functional outcomes (creatinine, estimated glomerular filtration rate [eGFR]) and postoperative symptoms (visual analogue pain scale) were assessed. RESULTS: The median operating time and blood loss were 180 min and 100 mL, respectively. There were no conversions to open surgery and no intraoperative transfusions. The median length of stay, bladder catheter indwelling time and stent removal were 4, 7 and 30 days, respectively. The median follow-up was 24 months. Overall, 10 patients (27%) had postoperative complications and of these, eight (22%) and two (5.4%) were Clavien-Dindo Grade I-II and III, respectively. At the last follow-up, the median postoperative creatinine level and eGFR were 0.9 mg/dL and 73.5 mL/min/1.73 m2 , respectively. At the last follow-up, five (13.5%) and three (8%) patients had Grade 1 hydronephrosis and mild urinary symptoms, respectively. The study limitations include its retrospective nature. CONCLUSION: In the present study, we present our RABFUR and RAPHUR techniques. We confirm the feasibility and safety profile of both approaches in patients with distal ureteric disease relying on the largest single-centre series with ≥1 year of follow-up.

RESUMO

INTRODUCTION AND HYPOTHESIS: Ureteral injury during gynecological surgery can be managed in a variety of ways, from endoscopic stent placement to ureteroneocystotomy with accompanying psoas hitch and/or Boari flap. The majority of these occur during hysterectomy; therefore, gynecologic surgeons may not be as familiar with repair in women with intact uteri. Herein we present our technique for delayed robotic-assisted ureteral reimplant and psoas hitch in a woman with a ureteral injury sustained during cesarean section, which initially presented as a uretero-cervical fistula. METHODS: In this video, we describe the evaluation and surgical management of a patient with delayed recognition of a left distal ureteral injury sustained during cesarean section. We present necessary modifications to robotic-assisted laparoscopic ureteroneocystostomy and psoas hitch to accommodate an intact uterus including the need for uterine manipulation, division of the round ligament, bladder mobilization from the lower uterine segment and development of the retropubic space, reimplantation steps, and psoas hitch. CONCLUSIONS: Simple modifications to a traditional technique of robotic-assisted ureteroneocystotomy effectively compensate for the presence of a uterus. Obstetricians should maintain a high index of suspicion for ureteral injury in women with new-onset severe urinary leakage post-cesarean section.

RESUMO

Objectives: To present the short-term and long-term outcomes of the psoas hitch procedure in a large cohort with long-term follow-up. Patients and methods: A multicenter, retrospective cohort study was conducted. Patients were included if they had undergone an open psoas hitch procedure with ureteral reimplantation for different types of distal ureteral pathology between 1993 and 2017. Clinical failure was defined as radiologically-proven obstruction of the ureteroneocystostomy and/or post-operative complaints requiring additional surgery. Pre-operative demographic data and post-operative radiological imaging were collected. Complications were categorized as peri-operative, acute (<30 days), and long-term complications. Results: A total of 166 patients had undergone a psoas hitch procedure, with a median follow-up of 15 months (IQR 6-45). Indications for the procedure included intra-operative injury of the ureter during gynecological, urological or general surgery, transitional cell carcinoma of the distal ureter, fistulae, (radiation) fibrosis, and trauma. There was no significant difference in pre- and post-operative estimated glomerular filtration rate. Post-operative complications included urinary leakage, recurrent urinary tract symptoms, recurrent malignancy, and kidney failure. Postoperative imaging was available in 143 patients. Failure of the psoas hitch procedure was seen in 8% (11/143) of the patients. In 55% (6/11) of these patients, radiation fibrosis was the indication for the psoas hitch procedure. Conclusion: This study provides greater insight into the long-term complications of the open psoas hitch procedure in adults. The psoas hitch procedure can be considered a safe procedure for restoring the continuity of the ureter for different types of ureteral pathologies in adult patients. However, patients with a history of radiation therapy causing retroperitoneal fibrosis might be more prone to failure after the procedure.

RESUMO

Introduction: Ureteral reimplantation is indicated for patients with congenital distal ureteral strictures, for iatrogenic intraoperative distal ureteral injuries, and for those who require distal ureterectomy for transitional cell carcinoma. Methods: Using the da Vinci system from Intuitive, we demonstrate distal ureterectomy with reimplantation. Both a refluxing extravesical reimplant and nonrefluxing extravesical reimplant are shown. We also demonstrate modifications, including psoas hitch and Boari flap. Results: Robotic ureteral reimplantation with psoas hitch and Boari flap are demonstrated in a reproducible manner. Additional topics covered include the delineation of diseased ureter vs healthy ureter, the applications of indocyanine green, and the use of interoperative ureteral stents. Conclusions: Robotic ureteral reimplantation is safe and feasible when performed with proper technique. Ureteroscopy and near-infrared fluorescence technology facilitate improved detection of diseased ureteral segments. Key points include the maintenance of principles of open surgery such as a tension-free, watertight, and stented anastomosis.

RESUMO

INTRODUCTION: Describing the surgical and oncological outcome of bladder-preserving ureter reconstruction (BPUR) with segmental ureteral resection after major gynecologic surgery. MATHERIALS AND METHODS: Patients with BPUR admitted at a single institution between March 2012 and July 2018 were retrospectively analyzed. Surgical and oncological data were assessed. RESULTS: Forty-six women with gynecologic tumors involving the ureter were treated with BPUR. R0 resection was achieved in 40/46 patients (86.9%), while pathologic margins were microscopically positive in 6 women (13.1%). Overall, 12 women (26.0%) received radiotherapy before surgery: among them, 8 patients received neoadjuvant chemoradiotherapy. Twenty-six women underwent BPUR during primary surgery, whereas 20 (43.4%) required BPUR upon recurrence. Twenty-six patients (56.2%) were found to have hydronephrosis at pre-operative workup. The psoas bladder hitch was the most common procedure performed for urinary reconstruction (63%) with respect to direct reimplantation (37%). Fourteen patients (14/46 = 30.4%) experienced urological complications. Urinary leakage occurred in 9 patients (19.5%), specifically: 5 uretero-vaginal fistula, 3 uroperitoneum, 1 uretero-enteral fistula. There were 3 cases (6.5%) of hydronephrosis at the side of ureteroneocystostomy and 2 cases (4.3%) of unilateral renal impairment requiring nephrectomy. At multivariate analysis only pre-operative radiotherapy (p = 0.047) and a history of pelvic irradiation (p = 0.025) were independently associated with an increased risk of developing severe urinary complications. CONCLUSIONS: BPUR is feasible in gynecologic cancer with invasion of the urinary tract. However, since a slight increase of post-operative urological complications was observed in the previously irradiated fields, a personalized surgical planning is recommended for these women in the next future.

RESUMO

OBJECTIVE: To present our experience and technique with robot-assisted ureteroneocystostomy (RAUN) procedure in adults. METHODS: Between February 2015 and August 2018, a total of 30 (34 ureters) patients who underwent RAUN surgery under a single surgeon were retrospectively reviewed. Perioperative data such as age, sex, body mass index (BMI), American society of anesthesiologists score, estimated blood loss, surgical technique, operative time, complications, length of hospital stay, and stent removal time were recorded. During the follow-up, patients underwent renal function test, urinalysis, and renal ultrasound examination for evaluation. Success was defined as symptomatic and radiologic relieve. Lastly, a literature search was conducted to review all published articles regarding RAUN surgery in adults. RESULTS: The patients' mean age, BMI, EBL, operative time, and follow-up period were 45.4 years, 23.1 kg/m2, 65.6 mL, 182.9 min, and 21.3 months, respectively. The two most common indications for the surgery were benign ureteral strictures and ureteric injuries secondary to a previous radical hysterectomy. Of the 34 cases, 26 (76.5%) and 8 (23.5%) patients received primary RAUN and RAUN with psoas hitch technique, respectively. Refluxing RAUN method was performed in all cases. No intraoperative complications were found. Two patients had a radiologic and symptomatic recurrence; one was managed with a repeat surgery while the other received ureteral dilatation treatment. CONCLUSION: Both our study and the published literature showed that RAUN is a safe, less invasive, and effective surgical technique that can easily replicate the open ureteroneocystostomy for managing lower ureteral diseases.

RESUMO

The experience with robotic reconstructive surgery has been reported previously. Many studies have demonstrated that the use of robotic surgery for those procedures is safe and effective. However, the characteristics related to those cases, make reconstructive surgery a very complex procedure that is usually managed in some referral centers only. Indocyanin green (ICG) is a substance that could be visualized using near-infrared fluorescence (NIRF). This fluorescence could help the surgeon for orientation and evaluation of viability of the tissues. OBJECTIVE: This article describes the literature and our experience using ICG for reconstructive surgery of the ureter. METHODS: We describe the literature and our approach for the evaluation and treatment of the ureteral stricture using ICG. CONCLUSION: The use of ICG has demonstrate to be safe, easy to perform and reproducible. In this article, we showed the ICG usefulness for complex reconstructive cases. Prospective studies with long follow up and bigger simple will permit a better evaluation of its results.


La experiencia con la cirugía reconstructiva asistida por robot ha sido reportada previamente. Dichos estudios han demostrado que el uso del robot en este tipo de procedimientos es seguro y eficaz. Sin embargo, las características de este tipo de casos hacen que la cirugía reconstructiva sea altamente compleja y por ende realizada solo en algunos centros de referencia. La ausencia de tacto durante la cirugía robótica hace que el cirujano dependa de ciertas claves visuales para su orientación. La indocianina verde (ICV) es un tinte que puede ser visualizado usando fluorescencia cercana a la luz infrarroja (FCLI). Dicha fluorescencia puede ser utilizada tanto para la orientación del cirujano como para la evaluación de la viabilidad de tejidos.OBJETIVO: En este artículo describimos el uso reportado en la literatura y nuestra experiencia utilizando ICV en cirugía reconstructiva, principalmente ureteral.MÉTODOS: Describimos nuestro abordaje en la evaluación y tratamiento de pacientes con estrechez ureteral usando ICV. A la vez, hacemos una revisión de los estudios previos realizados sobre este tema.CONCLUSIÓN: El uso de ICV ha demostrado ser seguro, fácil de realizar y repetir. La literatura y nuestra experiencia demuestra su utilidad en casos reconstructivos complejos. Estudios prospectivos a largo plazo y mayor escala permitirán evaluar mejor estos resultados.

RESUMO

Defects in ureteral continuity and function can originate from various etiologies such as stricture, radiotherapy, tuberculosis, tumor, trauma or perforation due to iatrogenic injury. The surgical options for the management of ureteral defects are complex and depend on the location of the defect. The aim of the surgical management of ureteral stricture is the reconstruction of an anti-refluxive and nonobstructive flow of urine to preserve kidney function. There are numerous possibilities for the reconstruction of ureteral defects ranging from ureteroneocystostomy with or without psoas-hitch- or Boari-flap to ileal ureteral replacement. Nearly all these techniques can either be done in open surgery or in a laparoscopically or robotic-assisted manner. The technique of robotic-assisted reconstruction of ureteral defects is challenging but offers a great opportunity. The aim of this article is to provide an overview of current surgical procedures in ureteric reconstruction.

RESUMO

OBJECTIVE: This paper describes our initial experience with laparoscopic ureteroneocystostomy in two patients with distal ureter lesions following gynaecological surgery (hysterectomy). Furthermore, we review the evidence on the incidence, prevention, and management of urinary tract injuries that occur during laparoscopic gynaecological surgery. METHOD: Two patients with iatrogenic lower ureteral injuries during hysterectomy leading to ureterovaginal fistula underwent laparoscopic ureteroneocystostomy with a psoas hitch. RESULTS: The procedures were successfully performed without any conversion. No intraoperative or postoperative complications were noted. Our minimally invasive approach has yielded successful results, similar to those achieved through open surgical repair. CONCLUSION: Laparoscopic ureteroneocystostomy with a psoas hitch for ureterovaginal fistula secondary to hysterectomy is a safe and feasible option for patients with gynecologic distal ureteral injury, with excellent results and low morbidity.


OBJETIVO: Presentamos nuestra experiencia inicial mediante ureteroneocistostomía laparoscópica en dos pacientes con lesión del uréter distal tras cirugía ginecológica (histerectomía). A su vez, se lleva a cabo una revisión de la literatura acerca de la incidencia, prevención y manejo de las lesiones urinarias secundarias a cirugía laparoscópica ginecológica.MÉTODO: Presentamos dos pacientes con fístula ureterovaginal tras lesión ureteral distal post-histerectomía, que son sometidos a ureteroneocistostomía por vía laparoscópica aplicando la técnica de vejiga psóica. RESULTADOS: Ambos procedimientos se realizaron con éxito sin necesidad de reconversión a cirugía abierta. No se objetivaron complicaciones intra ni postoperatorias. Nuestro enfoque mínimamente invasivo ofrece excelentes resultados, similares a los obtenidos en la reparación quirúrgica por vía abierta. CONCLUSIÓN: El tratamiento de la fístula ureterovaginal secundaria a lesión ureteral distal post-histerectomía, mediante ureteroneocistostomía laparoscópica aplicando técnica de vejiga psóica, es una técnica factible y segura, con buenos resultados y bajas tasas de morbilidad asociada.

RESUMO

PURPOSE: The purpose of this study is to evaluate our experience of laparoscopic ureteroneocystostomy for mid and lower ureteral stricture in a tertiary center in North India. MATERIALS AND METHODS: A total of 20 laparoscopic ureteroneocystostomy were performed with or without bladder flap procedures in 20 patients (13 females and 7 males) with various etiologies such as ureteric stricture, ureterovaginal fistula, endometriosis, and distal ureteric tumor at our hospital in a time frame from August 2013 to January 2017. Eight cases each presented after laparoscopic/open hysterectomy and postureterorenoscopic stone removal while two cases each presented secondary to endometriosis and distal ureteric tumor. Simple laparoscopic ureteroneocystostomy in 4, psoas hitch in 9, and Boari flap was done in 7 cases. RESULTS: The mean patient age was 44.2 years (range 19-65), mean surgical time was 184.25 min (115-250 min.), mean amount of bleeding was 153.25 mL (90-250 mL), and mean hospital stay was 3.05 days (2-7 days). Female-to-male ratio was 1.3:0.7. There was one conversion to open during laparoscopic Boari reimplant because of inadvertent injury to external iliac vein. The mean follow-up was 22.35 months (6-45). All the patients were asymptomatic with the resolution of hydronephrosis on ultrasound and without any significant obstruction on renal scan. CONCLUSIONS: Laparoscopic ureteroneocystostomy with or without bladder flap (Boari) provides good functional outcomes with excellent success rates and minimal morbidity comparable to open surgery in patients with ureteric stricture.

RESUMO

INTRODUCTION: The most important prognostic factor for oncological outcome of rectal cancer is radical surgical resection. In patients with locally advanced T4 rectal cancer (LARC) or locally recurrent rectal cancer (LRRC) (partial) resection of the urinary tract is frequently required to achieve radical resection. The psoas bladder hitch (PBH) technique is the first choice for reconstruction of the ureter after partial resection and this bladder-preserving technique should not influence the oncological outcome. METHODS: Demographic and clinical data were collected prospectively for all patients operated on for LARC or LRRC between 1996 and 2014 who also underwent a psoas hitch ureter reconstruction. Urological complications and oncological outcome were assessed. RESULTS: The sample comprised 70 patients, 30 with LARC and 40 with LRRC. The mean age was 62 years (range: 39-86). Postoperative complications occurred in 38.6% of patients, the most frequent were urinary leakage (22.9%), ureteral stricture with hydronephrosis (8.6%) and urosepsis (4.3%). Surgical re-intervention was required in 4 cases (5.7%), resulting in permanent loss of bladder function and construction of a ureter-ileo-cutaneostomy in 3 cases (4.3%). Oncological outcome was not influenced by postoperative complications. CONCLUSION: The rate of complications associated with the PBH procedure was higher in our sample than in previous samples with benign conditions, but most complications were temporary and did not require surgical intervention. We conclude that the bladder-sparing PBH technique of ureter reconstruction is feasible in locally advanced and recurrent rectal cancer with invasion of the urinary tract after pelvic radiotherapy.
