BMC Urol 2024; 24:118. [PMID: 38858691 PMCID: PMC11163719 DOI: 10.1186/s12894-024-01509-5] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/10/2024] [Accepted: 06/04/2024] [Indexed: 06/12/2024] Open
Abstract
PURPOSE To present the experience of ileal ureter with ileocystoplasty (IUC), and compare the outcomes of IUC in minimally invasive procedures to open procedures. PATIENTS AND METHODS From December 2017 to April 2023, twenty patients underwent IUC in open or minimally invasive (including laparoscopic and robotic) procedures. The baseline characteristics, perioperative data and follow-up outcomes were collected. Success was defined as relief of clinical symptoms, stable postoperative serum creatine and absence of radiographic obstruction. The perioperative and follow-up outcomes of open procedures and minimally invasive procedures were compared. RESULTS The etiology included pelvic irradiation (14/20), urinary tuberculosis (3/20) and surgical injury (3/20). Bilateral ureter strictures were repaired in 15 cases. The surgeries conducted consisted of open procedures in 9 patients and minimally invasive procedures in 11 patients. Compared to open procedures, minimally invasive surgeries had less median estimated blood loss (EBL) (100 ml vs. 300 min, p = 0.010) and shorter postoperative hospitalization (27 d vs. 13 d, p = 0.004). Two patients in the open group experienced grade 3 complications (sigmoid fistula and acute cholecystitis in one patient, and pulmonary embolism in another patient). Over a median follow-up period of 20.1 months, the median bladder functional capacity was 300 ml, with a 100% success rate of IUC. CONCLUSION IUC is feasible in both open and minimally invasive procedures, with acceptable complications and a high success rate. Minimally invasive procedures can have less EBL and shorter postoperative hospitalization than open procedure. However, prospective studies with larger groups and longer follow-up are needed.

Int Urol Nephrol 2024; 56:1817-1824. [PMID: 38285099 DOI: 10.1007/s11255-023-03927-0] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/29/2023] [Accepted: 12/17/2023] [Indexed: 01/30/2024]
Abstract
PURPOSE To explore the role of the Whitaker test in evaluating the postoperative outcome of upper urinary tract reconstruction surgery in patients carrying a nephrostomy tube after surgery. PATIENTS AND METHODS This was a prospective observational study performed in 42 patients with nephrostomy tube undergoing the Whitaker test after upper urinary tract reconstruction surgery between January 2020 and December 2021. Data on clinical information, the Whitaker test and surgical procedure were collected prospectively, and the long-term follow-up results were analysed retrospectively. RESULTS The 46 ureters of 42 patients (right 16, left 22, bilateral 4) underwent six common upper urinary tract surgical reconstruction procedures and one combined procedure, including pyeloplasty, ureteroureterostomy, lingual mucosal onlay graft, appendiceal onlay flap, ureteral reimplantation, Boari flap, and ipsilateral lingual mucosal onlay graft combined ureteral reimplantation. All patients underwent the Whitaker test successfully without any discomfort after examination. The postoperative Whitaker test showed 43 kidneys without obstruction and 3 kidneys with obstruction. At a median follow-up of 18 months (range 13-31), the follow-up results showed that the overall success rate of the surgery was 100% (46/46). Concerning the concordance Whitaker test and follow-up results, the observed proportion of agreement was 93.5% (43/46). CONCLUSION The Whitaker test can achieve similar consistency with the long-term follow-up results after upper urinary tract reconstruction surgery and can be used as a tool to evaluate the surgical efficacy of upper urinary tract reconstruction surgery, which can provide a prognostic efficacy evaluation for patients carrying a nephrostomy tube after surgery.

[PMID: 37828507 PMCID: PMC10571485 DOI: 10.1186/s12894-023-01333-3] [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: 04/06/2023] [Accepted: 10/03/2023] [Indexed: 10/14/2023] Open
Abstract
BACKGROUND To summarize the efficacy of combined robot-assisted laparoscopy and ureteroscopy in treating complex ureteral strictures. METHODS Eleven patients underwent combined robot-assisted laparoscopy and ureteroscopy for ureteral strictures between January 2020 and August 2022. Preoperative B-ultrasound, glomerular filtration rate measurement, and intravenous pyelography showed different degrees of hydronephrosis in the affected kidney and moderate to severe stenosis in the corresponding part of the ureter. During the operation, stricture segment resection and end-to-end anastomosis were performed using the da Vinci robot to find the stricture point under the guidance of a ureteroscopic light source in the lateral or supine lithotomy position. RESULTS All the patients underwent robot-assisted laparoscopy and ureteroscopy combined with end-to-end ureterostenosis. There were no conversions to open surgery or intraoperative complications. Significant ureteral stricture segments were found in all patients intraoperatively; however, stricture length was not significantly different from the imaging findings. Patients were followed up for 3-27 months. Two months postoperatively, the double-J stent was removed, a ureteroscopy was performed, the ureteral mucosa at the end-to-end anastomosis grew well, and the lumen was patent in all patients. Furthermore, imaging examination showed that hydronephrosis was significantly improved in all patients, with grade I hydronephrosis in three cases and grade 0 hydronephrosis in eight cases. No recurrence of ureteral stricture was observed in patients followed up for > 1 year. CONCLUSION Robot-assisted laparoscopy combined with ureteroscopy is an effective method for treating complex ureteral strictures and can achieve accurate localization of the structured segment.

Abstract
INTRODUCTION Robotic ureteral reconstruction (RUR) has been widely used to treat ureteral diseases. To summarize the surgical techniques, complications, and outcomes following RUR, as well as to compare data on RUR with open and laparoscopic ureteral reconstruction. METHODS Our systematic review was registered on the PROSPERO (CRD42022309364) database. The PubMed, Cochrane and Embase databases were searched for publications in English on 06-Feb-2022. Randomised-controlled trials (RCTs) or non-randomised cohort studies with sample size ≥ 10 cases were included. RESULTS A total of 23 studies were included involving 996 patients and 1004 ureters from 13 non-comparative, and 10 retrospective comparative studies. No RCT study of RUR was reported. The success rate was reported ≥ 90% in 15 studies. Four studies reported 85-90% success rate. Meta-analyses for comparative studies showed that RUR had significantly lower estimated blood loss (EBL) (P = 0.006) and shorter length of stay (LOS) (P < 0.001) than the open approach. RUR had shorter operative time than laparoscopic surgery (P < 0.001). CONCLUSIONS RUR is associated with lower EBL and shorter LOS than the open approach, and shorter operative time than the laparoscopic approach for the treatment of benign ureteral strictures. However, further studies and more evidence are needed to determine whether RUR is more superior.

Robotic versus laparoscopic ureteroplasty with a lingual mucosa graft for complex ureteral stricture. Int Urol Nephrol 2023; 55:597-604. [PMID: 36327006 DOI: 10.1007/s11255-022-03385-0] [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: 08/18/2022] [Accepted: 09/29/2022] [Indexed: 11/06/2022]
Abstract
PURPOSE Ureteroplasty with a lingual mucosa graft (LMG) for complex ureteral stricture was reported promising. We aimed to compare outcomes of robotic versus laparoscopic ureteroplasty using a LMG (RU-LMG vs. LU-LMG, respectively). METHODS From October 2018 to January 2021, 32 ureteroplasties using LMGs were performed by one experienced surgeon, including 16 robotic and laparoscopic procedures each. Patient demographics and peri-operative, post-operative, and follow-up data were prospectively collected and compared. RESULTS The robotic group had a higher rate of previous reconstruction than the laparoscopic group (62.50% vs. 18.75%; p = 0.012). The stricture length was significantly longer in the robotic group (4.8 ± 1.2 cm) than the laparoscopic group (3.7 ± 1.2 cm; p = 0.013). All procedures were completed successfully without open conversion. The operative time was shorter in the robotic group (192 ± 54 min) than the laparoscopic group (254 ± 46 min; p = 0.001). The robotic group had a shorter length of post-operative stay (6.1 ± 2.4 d vs. 8.9 ± 4.3 d; p = 0.033) but a higher hospital cost (76,801 ± 17,974 vs. 42,214 ± 15,757 RMB; p < 0.001) than the laparoscopic group. The mean follow-up time was 21 ± 7 months for the robotic group and 29 ± 9 months for the laparoscopic group respectively (p = 0.014). No difference was detected in the success rate (93.75% and 100%, respectively; p = 0.309) and complication rate (18.75% and 31.25%, respectively; p = 0.414) between the robotic and laparoscopic groups. CONCLUSION Both RU-LMG and LU-LMG are feasible, effective, and safe for repair of complex ureteral strictures. RU-LMG had a shorter operative time and a shorter length of post-operative stay but a higher hospital cost.

Laparoscopic ureteroplasty with oral mucosal graft for ureteral stricture: Initial experience of eighteen patients. Asian J Surg 2023; 46:751-755. [PMID: 35835671 DOI: 10.1016/j.asjsur.2022.06.156] [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: 01/06/2022] [Revised: 06/12/2022] [Accepted: 06/30/2022] [Indexed: 02/08/2023] Open
Abstract
OBJECTIVE To investigate the feasibility and clinical efficacy of laparoscopic ureteroplasty with oral mucosal graft for ureteral stricture and describe the initial experience of eighteen operations. METHODS A retrospective analysis was performed on the clinical data of 18 patients who underwent laparoscopic ureteroplasty with oral mucosal graft for long segment or complex ureteral stricture admitted to the Second Affiliated Hospital of Anhui Medical University from July 2018 to June 2021. After the stricture ureter segment was freed during the operation, the ureteral stenosis segment was longitudinally cut. The required oral mucosa is removed according to the length of the stenosis. Oral mucosal grafts were harvested and placed in the ureter as an anterior onlay with omental wrapping. RESULTS Ureteral repair was performed laparoscopically in all cases, with no conversion to open surgery and no serious complications. The median length of ureteral stenosis was 3 cm (range, 2-7 cm), the mean operative time was 205.8 ± 33.4 min, indwelling time of the drainage tube was 4.9 ± 1.6 days, and the median length of postoperative stay was 7 days (range, 4-14 days). The double J tube was removed three to six weeks postoperatively. One of the eighteen patients had restenosis after surgery, and the other patients showed no deterioration of the severity of the obstructive uropathy after follow-up imaging examination. CONCLUSION Laparosopic ureteroplasty with oral mucosal graft is a simple, safe and efficient option for the treatment of ureteral stricture. Although the results of the initial experience are encouraging, a large cohort study with longer follow-up period is need to be done.

Abstract
BACKGROUND Complete intracorporal robotic ileal ureteric replacement is challenging. We aimed to present the surgical technique of robotic ileal ureter replacement with extracorporeal ileal segment preparation for long ureteral strictures. METHODS From March 2019 to March 2021, 18 patients underwent robotic ileal ureter replacement with extracorporeal ileal segment preparation by one experienced surgeon. The demographic, perioperative, and follow-up data were recorded. Success was defined as the resolution of the presenting symptom, a stable estimated glomerular filtration rate and unobstructive drainage on imaging examination. RESULTS All 18 surgeries were successfully completed without conversion. The median length of the intestinal tube used was 20 (12-30) cm. The median operative time was 248 (170-450) min, the median estimated blood loss was 50 (10-200) ml, and the median postoperative hospital stay was 7 (5-27) days. At a median follow-up of 16 (13-28) months, all patients were symptom-free. No or mild hydronephrosis was confirmed in 17 patients; 1 patient had moderate hydronephrosis without peristalsis of the ileal ureter. The renal function was stable in all patients. The overall success rate was 100%. Postoperative complications, including 4 cases of urinary infections (Grade I), 1 case of an incision hernia (Grade I), 4 cases of kidney stone formation (Grade I), 6 cases of metabolic acidosis (Grade I), 4 cases of incomplete ileus (Grade II), and 1 case of an incision infection (Grade IIIb). CONCLUSIONS Robot-assisted laparoscopic ileal ureter replacement with extracorporeal ileal segment preparation is safe, feasible, and effective for the treatment of long ureteral strictures, especially in high-volume tertiary referral centers with extensive robotic surgery experience capable of managing severe peri-operative complications.

Lingual Mucosal Graft Ureteroplasty for Long Proximal Ureteral Stricture: 6 Years of Experience with 41 Cases. Eur Urol 2022; 82:193-200. [PMID: 35618522 DOI: 10.1016/j.eururo.2022.05.006] [Citation(s) in RCA: 13] [Impact Index Per Article: 6.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/01/2022] [Revised: 03/26/2022] [Accepted: 05/10/2022] [Indexed: 11/29/2022]
Abstract
BACKGROUND Management of a long proximal ureteral stricture is challenging. Lingual mucosal graft ureteroplasty (LMGU) is a novel minimally invasive technique for ureteral reconstruction that avoids the morbidity of bowel interposition or autotransplantation. OBJECTIVE To evaluate the long-term effectiveness of LMGU for managing long, complex proximal ureteral strictures in a multi-institutional cohort of patients. DESIGN, SETTING, AND PARTICIPANTS This retrospective study involved data for 41 patients treated with LMGU at three centers between June 2015 and January 2021. SURGICAL PROCEDURE LMGU was performed using either an onlay ureteroplasty in which the diseased ureter was incised ventrally and repaired with a lingual mucosal graft (LMG) to widen the ureteral lumen, or an augmented anastomotic technique in which the obliterated segment of the ureter was excised and reanastomosed primarily on dorsal side, and an LMG was placed on the ventral side. MEASUREMENTS Pre-, intra-, and postoperative variables and outcomes were assessed. A descriptive statistical analysis was performed. RESULTS AND LIMITATIONS Of 41patients, 40 were operated with laparoscopic procedures and one with a robot. Twenty-four (59%) patients underwent an onlay ureteroplasty, and 17 (41%) underwent an augmented anastomotic ureteroplasty. The reconstructed ureter was wrapped with omentum in 90% of cases. The median (range) stricture length was 4.8 cm (2.0-8.0), operative time was 166 min (98-306), and estimated blood loss was 65 ml (15-220). No open conversions and intraoperative complications occurred. At a median follow-up of 35 mo (range 13-80), the overall success rate was 97.6% (40/41). CONCLUSIONS LMGU is a safe, feasible, and effective long-term technique for managing long, complex proximal ureteral strictures. PATIENT SUMMARY We reported a novel technique for long proximal complex ureteral strictures using an onlay lingual mucosal graft (LMG). Our 6-yr outcomes demonstrate that onlay LMG ureteroplasty is a safe, feasible, and effective long-term procedure for ureteral reconstruction.

Abstract
BACKGROUND Robot-assisted autologous graft ureteroplasty provides another treatment option for complex ureteral strictures, circumventing ileal ureter or renal autotransplantation. OBJECTIVE To report the medium-term outcome of robotic ureteroplasty with a lingual mucosal graft (RU-LMG) for managing complex ureteral strictures. DESIGN, SETTING, AND PARTICIPANTS Between June 2019 and September 2020, 12 patients underwent RU-LMG. The perioperative variables were prospectively collected, and the outcomes were assessed. SURGICAL PROCEDURE After ureteral stricture dissection, the narrow segment was cut longitudinally, and a lingual mucosal graft (LMG) of the required length was harvested, followed by double-J stent placement and LMG ventral onlay anastomosis. If the diseased ureter required transection, posteriorly augmented ureteral anastomosis could be performed before LMG harvest. Finally, the anastomotic area was wrapped by the omental flap. MEASUREMENTS A descriptive statistical analysis was performed. The criteria for complete success included the absence of both clinical symptoms and obstruction on radiography. RESULTS AND LIMITATIONS Seven patients (58%) had a history of failed ureteral reconstruction. The mean (range) stricture length was 4.7 (3-6.5) cm, LMG length was 4.4 (3-7) cm, LMG width was 1.5 (1-2) cm, operative duration was 197.1 (130-346) min, estimated blood loss was 49.2 (10-200) ml, and the duration of postoperative hospitalization was 6 (4-14) d. No open conversions and intraoperative complications occurred. The median follow-up time was 15 mo (range: 13-27 mo). The overall success rate was 92% (11/12). CONCLUSIONS These medium-term follow-up results demonstrate that RU-LMG is a safe and feasible technique for repairing ureteral strictures. PATIENT SUMMARY Our study proves that robotic ureteroplasty with a lingual mucosal graft is a safe and feasible technique for ureteral reconstruction that can serve as another choice for managing long, complex ureteral strictures.

Abstract
OBJECTIVE The objective of this study is to introduce a novel technique of robotic-assisted laparoscopic pyeloplasty (RALP) for ureteropelvic junction obstruction (UPJO) with long proximal ureteral stricture in children. MATERIALS AND METHODS Clinical information on patients who underwent a modified RALP between July 2018 and May 2019 in our center was collected retrospectively. Our surgical modifications mainly include "double-flap" tailoring of the renal pelvis and anastomosis of spatulate ureter with the double-flap. Demographic, perioperative, postoperative, and follow-up information was recorded in detail. RESULTS A total of 13 patients were included in the study. All the patients underwent a modified RALP without conversion to open surgery. They were followed up with a median time of 36 months. The anteroposterior diameter of the renal pelvis was 1.19 ± 0.21 at 6 months after the surgery, which was significantly lower than that on admission (3.93 ± 0.79). The split renal function of the children was also significantly improved from 0.37 ± 0.05) to 0.46 ± 0.02 at 6 months after surgery (p < 0.05). The diuretic renography revealed that all the patients have a T1/2 time less than 20 min postoperatively. The children were in good condition during the follow-up period. CONCLUSIONS Modified RALP is an effective surgical treatment for children with UPJO with long proximal ureteral stricture. The success rate of this modification has been preliminarily confirmed.

Should ureteroscopy be performed for patients after ureteral reconstruction with autologous onlay flap/graft? Transl Androl Urol 2021; 10:3737-3744. [PMID: 34804817 PMCID: PMC8575567 DOI: 10.21037/tau-21-583] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/02/2021] [Accepted: 08/26/2021] [Indexed: 11/06/2022] Open
Abstract
Background To analyze the safety and clinical significance of performing ureteroscopy after ureteral reconstruction with autologous onlay/graft. To describe the ureteroscopic appearances of the appendiceal onlay flap and lingual mucosa graft. Methods Beginning in August 2018, we conducted a prospective cohort study of autologous onlay/graft techniques to repair ureteral strictures. The perioperative data of 42 patients who had undergone surgery more than 6 months prior were collected prospectively. During the postoperative follow-up, ureteroscopy was performed in 27 patients (64.3%) after surgery (group A), and ureteroscopy was not performed in the other 15 patients (35.7%) (group B). We carried out a comparative study of these two groups of patients. Analyses were conducted mainly on complications related to ureteroscopy and the success rate of ureteral reconstruction surgery. Results There were no significant differences in patient demographic data or the length of ureteral reconstruction between the two groups (P>0.05). For the ureteroscopy group, the median time from repair surgery to ureteroscopy was 3 (range, 2-7) months, there was no poor healing of the anastomosis, and the ureteral lumen of all patients was unobstructed. Some expected observations can be found in the ureteral lumen, such as mucosa edema, stones, follicles and granulation tissue. Among the 27 patients, one patient (3.7%) developed bleeding intraoperatively and 7 patients (25.9%) were found to have low-grade (Clavien-Dindo I and II) postoperative complications, including 5 cases of fever and 2 cases of bleeding. The mean follow-up times of patients in group A and group B were 16.7±6.4 and 19.0±10.1 months, respectively. The objective success (imaging showed hydronephrosis ease) rate of the two groups was 100%. The subjective success (symptom relief) rates of group A and group B were 96.3% and 100%, respectively. Conclusions Patients after autologous onlay flap/graft ureteroplasty do not need to undergo routine ureteroscopy unless there is aggravation of hydronephrosis or other indications for ureteroscopy, such as stones.

A ureteral stricture disease score and classification system: correlation with upper urinary tract reconstructive surgery complexity. Transl Androl Urol 2021; 10:3745-3755. [PMID: 34804818 PMCID: PMC8575562 DOI: 10.21037/tau-21-575] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/30/2021] [Accepted: 09/02/2021] [Indexed: 11/15/2022] Open
Abstract
Background To develop an original and standardized ureteral stricture disease (USD) score and classification system for quantifying ureter stricture characteristics, assessing complexity of the minimally invasive upper urinary tract reconstructive (UUTR) surgical procedure, formulating preoperative plans, and offering objective comparisons of surgical techniques between different institutions and surgeons. Methods We retrospectively reviewed a test set of 64 patients and a validation set of 170 patients who underwent minimally invasive UUTR surgery from January 2018 to January 2021. Three factors were selected to be included in the USD score and classification system: (I) stricture etiology (E, 1–2 points); (II) stricture segment (S, 0–3 points); and (III) length of stricture (L, 1–5 points). The UUTR surgery involves low-complex surgeries (cystoscopy with ureteral dilation and stent placement, ureteropyeloplasty, end to end repair, ureteral reimplantation) and high-complex surgeries (onlay repair (buccal mucosae, lingual mucosae, appendix mucosae), Boari flap repair and ileal ureter replacement). Estimated blood loss and operative time were used as surrogate indicators of surgical complexity. Results The interrater reliability of the USD score and classification system was 0.908. A linear relationship between the USD score and estimated blood loss was observed (rs =0.676, P<0.001). The USD score was also correlated with operative time (rs =0.638, P<0.001). A significant difference in USD scores was found between the high and low complexity surgery groups (4 vs. 7, P<0.001). Variability of UUTR surgery is based on USD classification system, but with regularity to conform to. Conclusions The USD score and classification system is a concise, easily applicable, and validated scale to delineate the clinically significant features of ureter stricture that correlate with the complexity of the UUTR surgical procedure. The use of this score and classification system can facilitate preoperative plan and comparison of USD treatments in clinical practice and urological literature. Research with large sample is needed to further examine and modify the use of the system.
