Impact of intra-abdominal pressure on early kidney transplant outcomes. Sci Rep 2022; 12:2257. [PMID: 35145181 PMCID: PMC8831606 DOI: 10.1038/s41598-022-06268-7] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/18/2021] [Accepted: 01/06/2022] [Indexed: 12/13/2022] Open
Abstract
Increased intra-abdominal pressure (IAP) is common among post-surgical patients and may cause organ dysfunction. However, its impact after kidney transplantation on early postoperative complications and graft recovery remains unclear. We designed a prospective, observational cohort study to describe the prevalence and determinants of IAP, as well as its effect on delayed graft function, postoperative complications, and graft recovery. IAP was measured in 205 kidney transplant recipients every 8 h during the first 72 h after surgery using the urinary bladder technique. Intra-abdominal hypertension was defined as IAP ≥ 12 mmHg. Patients were followed for 6 months or until graft failure/death. Mean IAP was 12 ± 3.3 mmHg within the first 24 h. 78% of subjects presented with intra-abdominal hypertension during the first 72 h. Increased IAP was associated with higher renal resistive index [r = 0.213; P = 0.003] and lower urine output [r = - 0.237; P < 0.001]. 72 h mean IAP was an independent risk factor for delayed graft function [OR: 1.31; 95% CI: 1.13-1.51], postoperative complications [OR: 1.17; 95% CI: 1.03-1.33], and absence of graft function recovery [HR for graft function recovery: 0.94; 95% CI: 0.88-0.99]. Increased IAP was highly prevalent after transplantation and was independently associated with delayed graft function, postoperative complications, and absence of graft function recovery. Routine IAP monitoring should be considered post-transplantation to facilitate early recognition of relevant complications.

Urology 2022; 165:336-342. [PMID: 35065141 DOI: 10.1016/j.urology.2022.01.014] [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: 11/07/2021] [Revised: 01/09/2022] [Accepted: 01/09/2022] [Indexed: 11/26/2022]
Abstract
OBJECTIVES To describe a stentless modified Lich-Gregoir technique (mLG) for ureteroneocystostomy in renal transplantation (RT), with early bladder catheter (BC) removal (under 48 hours), and compare the postoperative results with those of the traditional technique (LG) with routine bladder catheter removal (4 to 5 days). The modification consists of maintaining a thin layer of detrusor fibers covering the bladder mucosa during dissection, which is incorporated into the anastomosis to reinforce the ureteroneocystostomy. MATERIALS AND METHODS This retrospective cohort study compared the postoperative outcomes of 100 consecutive patients who underwent mLG with early removal of BC between October 2018 to November 2019 with those of a historical cohort of 165 consecutive patients transplanted using stentless LG and routine removal of BC, who underwent surgery between July 2017 and September 2018. All transplants were performed by the same surgeon. Follow-up was 6 months. RESULTS Demographic characteristics were comparable, although patients in the mLG group had a higher mean preoperative urine volume (911±753.8mL vs. 629±638.6mL, p=0.016). Patients in the mLG group successfully underwent early BC removal (2.2±0.9 vs. 4.8±4.8 days, p<0.001), with no differences in the incidence of surgical or clinical complications, including urine leaks (1 vs. 3%, p=0.284). In addition, mLG patients presented a shorter mean length of hospital stay (6.5±5.0 vs. 7.1±6.2 days, p=0.023). CONCLUSION This stentless modified Lich-Gregoir technique enables safe early bladder catheter removal and is associated with reduced hospital length of stay.

Abstract
Due to atrophic bladder, patients undergoing long-term dialysis experience vesicoureteral reflux and complicated urinary tract infections after kidney transplantation. A 58-year-old woman underwent living donor kidney transplantation after 41 years of dialysis. She had no contraindications, with good cardiac function and minimal artery calcification despite the long history of hemodialysis. Immunosuppression was initiated with tacrolimus, mycophenolate mofetil, prednisolone, and basiliximab. Ureteroneocystostomy with an antireflux technique was carefully conducted as her bladder volume was 15 mL. The postoperative clinical course was uneventful with immediate graft function. The bladder volume gradually increased to 81 mL at discharge, 3 weeks postoperatively. The patient was initially depressed due to frequent urination early post-transplant but recovered soon after as the bladder volume gradually increased to 400 mL. The patient has not yet reported a urinary tract infection episode. This case highlights living donor kidney transplantation-induced recovery of bladder function with careful ureteroneocystostomy, despite the long dialysis history.

Abstract
INTRODUCTION Ureteric implantation of the transplanted ureter into native urinary bladder tissue in kidney transplantation recipients is essential for post-operative kidney function. We aimed to determine the effects of Taguchi versus Lich-Grégoir extravesical ureteroneocystostomy in kidney transplantation. METHODS We searched multiple databases (MEDLINE, Cochrane Library, and Web of Science), trial registries, and conference proceedings until March 2021. We included prospective studies comparing Taguchi and Lich-Grégoir ureteroneocystostomy in kidney transplantation. Two review authors independently screened the identified records, extracted data, evaluated the risk of bias using ROBINS-I, and assessed the certainty of evidence according to GRADE. RESULTS We identified 3 prospective studies with serious or critical risk of bias, leading to low-certainty evidence. We downgraded the risk of bias due to study limitations. Assessment and/or reporting of baseline imbalances, co-interventions, and confounding factors was insufficient in all included studies. The effect of Taguchi ureteroneocystostomy remains unclear. CONCLUSION Currently available evidence is not useful to determine the effect of Taguchi versus Lich-Grégoir ureteroneocystostomy in kidney transplantation. There is a need for methodologically better designed and executed studies, such as randomized controlled trials with long-term follow-up reporting baseline imbalances, co-interventions, and confounding factors.

Results of a previously unreported extravesical ureteroneocystostomy technique without ureteral stenting in 500 consecutive kidney transplant recipients. PLoS One 2021; 16:e0244248. [PMID: 33428659 PMCID: PMC7799771 DOI: 10.1371/journal.pone.0244248] [Citation(s) in RCA: 13] [Impact Index Per Article: 4.3] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/18/2020] [Accepted: 12/07/2020] [Indexed: 12/22/2022] Open
Abstract
Urologic complications can still occur following kidney transplantation, sometimes requiring multiple radiological and/or surgical procedures to fully correct the problem. Previously proposed extravesical ureteral reimplantation techniques still carry non-negligible risks of the patient developing urologic complications. About 10 years ago, a new set of modifications to the Lich-Gregoir technique was developed at our center, with the goal of further minimizing the occurrence of urologic complications, and without the need for initial ureteral stent placement. It was believed that an improvement in the surgical technique to minimize the risk of developing urologic complications was possible without the need for stent placement at the time of transplant. In this report, we describe the advantages of this technique (i.e., mobilized bladder, longer spatulation of the ureter, inclusion of bladder mucosa with detrusor muscle layer in the ureteral anastomosis, and use of a right angle clamp in the ureteral orifice to ensure that it does not become stenosed). We also retrospectively report our experience in using this technique among 500 consecutive (prospectively followed) kidney transplant recipients transplanted at our center since 2014. During the first 12mo post-transplant, only 1.4%(7/500) of patients developed a urologic complication; additionally, only 1.0%(5/500) required surgical repair of their original ureteroneocystostomy. Five patients(1.0%) developed a urinary leak, with 3/5 having distal ureteral necrosis, and 1/5 subsequently developing a ureteral stricture. Two other patients developed ureteral stenosis, one due to stricture and one due to ureteral stones. These overall results are excellent when compared with other reports in the literature, especially those in which routine stenting was performed. In summary, we believe that the advantages in using this modified extravesical ureteroneocystostomy technique clearly help in lowering the early post-transplant risk of developing urologic complications. Importantly, these results were achieved without the need for ureteral stent placement at the time of transplant.

Abstract
Abstract
Purpose of Review
In the setting of kidney transplantation, the ureter is a common source for complications. As a result, prevention of ureteral complications and their management is of crucial importance. In this context, the purpose of this review is to summarize recent literature on the ureter in the kidney transplant setting with a special focus on new findings. We conducted a PubMed and Medline search over the last 10 years to identify all new publications related to ureteroneoimplantations, stents and management of complications in the kidney transplant setting.
Recent Findings
Performance of the “Lich-Gregoir” technique for ureteroneocystostomy seems to be favourable in regard to postoperative complications when compared with other methods described in the literature. Moreover, major urologic complications can be further reduced by ureteral stenting.
Summary
A new approach for management of ureteral strictures in renal transplants is presented. We discussed the usage of a ureteral stent covered with a biostable polymer aiming to prevent tissue ingrowth into the lumen as a new option for management of ureteral stricture in the kidney transplant setting.

Abstract
Urological complications, especially urine leaks, remain the most common type of surgical complication in the early post-transplant period. Despite major advances in the field of transplantation, a small minority of kidney transplants are still being lost due to urological problems. Many of these complications can be traced back to the time of retrieval and implantation. Serial ultrasound examination of the transplanted graft in the early post-operative period is of key importance for early detection. The prognosis is generally excellent if recognized and managed in a timely fashion. The purpose of this narrative review is to discuss the different presentations, compare various ureterovesical anastomosis techniques and provide a basic overview for the management of post-transplant urological complications.

Abstract
BACKGROUND Renal transplantation is the treatment of choice for patients with stage V chronic kidney disease, which does not have contraindications to the procedure and is more cost-effective than dialysis treatments and provides better survival and quality of life. OBJECTIVE The objective of this study was to evaluate the incidence of postoperative complications in kidney transplant recipients in a reference hospital. METHODOLOGY This was a descriptive and retrospective study involving the analysis of patient records during hospitalization and outpatient treatment. We analyzed the demographics, clinical indicators, surgical techniques, and postoperative complications. RESULTS In the analysis of 147 transplantations, there was a higher incidence of transplantation in female recipients, average age of 37 years with a predominance of cadaveric transplantation. Of all pretransplantation comorbidities, hypertension was the most frequent. The overall incidence of surgical complications was 29.9%, with an incidence of vascular complications of 12.7%, 13.4% of surgical site complications, 8.2% of urologic complications, and 3% of hemorrhagic complications. DISCUSSION Vascular complications are serious complications and are associated with increased risk of graft loss (relative risk, 8.4), particularly arterial thrombosis. Patients with ureteral anastomosis using Lich-Gregoir technique showed lower urologic complications compared with patients with anastomosis by Leadbetter-Politano technique. CONCLUSION Surgical complications have different clinical effects, depending on their category. The vascular complications are associated with graft lost.

Abstract
BACKGROUND The incidence of urologic complications after kidney transplantation remains high despite improvements in diagnosis and operative techniques. Urinary tract reconstruction is usually done by ureteroneocystostomy (UCNS), and several techniques are available. In this study, we evaluated the outcomes of 2 different UCNS techniques performed in our department, the transvesical Leadbetter-Politano (L-P) and the extravesical Lich-Gregoire (L-G) technique. MATERIAL AND METHODS We evaluated the outcomes of 2 different UCNS techniques, L-P versus L-G, performed in our department between July 1, 2006, and December 31, 2011. During this period, we performed 524 consecutive renal transplantations-264 cases using the L-P technique (50.3%) and 260 cases with L-G technique (49.7%). Renal grafts were obtained from cadaveric donors in 146 cases (27.86%) and from living-related donors in 378 cases (72.14%). Recipient mean age was 35.64 years and the male to female ratio was 1.63:1. RESULTS Urologic complications after kidney transplantation occurred in 22 cases in the L-P UCNS group (8.33%). The most common complications were ureteral stenosis (3.41%) and leakage (2.65%). Other complications recorded were lymphoceles (1.89%) and hematoma with secondary ureteral obstruction (0.38%). Compared with the L-P UCNS technique, the L-G technique was associated with fewer overall complications (6.15% vs 8.33%; P = .06), a lesser rate of ureteral stenosis (2.31% vs 3.41%; P = .08), and a similar rate of leakage. However, statistical analysis revealed no differences between the 2 techniques (P = .06). In addition, we did not note any differences in graft and patient survival between the 2 groups. CONCLUSIONS In our study, the extravesical L-G technique has a lower complication rate compared with transvesical L-P procedure, but without statistical differences. Furthermore, the L-G technique is easier and faster to perform, it avoids a separate cystotomy, and requires a shorter ureteral length. In conclusion, we recommend L-G technique as technique of choice in kidney transplantation.

Abstract
OBJECTIVE To compare the outcomes of standard Lich-Gregoir technique and a modified one-stitch technique of ureteroneocystostomy in renal transplantation. PATIENTS AND METHODS Data from 645 transplant recipients by two different ureteroneocystostomy techniques were retrospectively reviewed at the first Affiliated Hospital, Medical College of Xi'an Jiaotong University, between January 2002 and December 2007. RESULTS There were 418 recipients in the Lich-Gregoir group and 227 in new one-stitch group. The overall ureteral complication rate for new one-stitch technique was 19.8 % (n = 45) as opposed to 15.79 % (n = 66) for the Lich-Gregoir technique. No significantly different rate of ureteral complications occurred in two groups (P > 0.05). In comparison, there was a higher proportion of hematuria at the limit of statistical significance in new one-stitch group (P < 0.05). Average operative time for the modified one-stitch and Lich-Gregoir techniques was 8.8 ± 1.4 and 21.9 ± 6.1 min, respectively (P < 0.05). Urinary tract infections, delayed graft function and rejection rates were not significantly different between the two groups (P > 0.05). CONCLUSION Although the modified one-stitch technique may predispose patients to higher rates of hematuria, it has no significant difference in ureteral complications compared with the Lich-Gregoir group. Based on this large series and data analyses, we believe that this new technique will become one of our multiple choices in our setting.

Abstract
BACKGROUND Major urological complications (MUCs) after kidney transplantation contribute to patient morbidity and compromise graft function. The majority arise from the vesicoureteric anastomosis and present early after transplantation. Ureteric stents have been successfully used to treat such complications. A number of centres have adopted a policy of universal prophylactic stenting, at the time of graft implantation, to reduce the incidence of urine leaks and ureteric stenosis. Stents are associated with specific complications and some centres advocate a policy of only stenting selected anastomoses. OBJECTIVES To examine the benefits and harms of routine ureteric stenting to prevent urological complications in kidney transplant recipients. SEARCH METHODS We searched the Cochrane Renal Group's Specialised Register (up to 8 January 2013) through contact with the Trials' Search Co-ordinator using search terms relevant to this review. SELECTION CRITERIA All RCTs and quasi-RCTs were included in our meta-analysis. DATA COLLECTION AND ANALYSIS Four reviewers assessed the studies for quality against four criteria (allocation concealment, blinding, intention-to-treat and completeness of follow-up). The primary outcome was the incidence of MUCs. Further outcomes of interest were graft and patient survival and the incidence of adverse events (urinary tract infection (UTI), haematuria, irritative symptoms, pain and stent migration). Statistical analyses were performed using the random effects model and the results expressed as relative risk (RR) with 95% confidence intervals (CI). MAIN RESULTS Seven RCTs (1154 patients) of low or moderate quality were identified. The incidence of MUCs was significantly reduced (RR 0.24, 95% CI 0.07 to 0.77, P = 0.02, NNT 13) by universal prophylactic stenting. This was dependent on whether the same surgeon performed, or was in attendance, during the operations. Two patients lost their grafts to infective urinary tract complications in the stented group. UTIs, in general, were more common in stented patients (RR 1.49, 95% CI 1.04 to 2.15) unless the patients were prescribed cotrimoxazole 480 mg/d: in which case the incidence was equivalent (RR 0.97, 95% CI 0.71 to 1.33). Stents appeared generally well tolerated, although studies using longer stents (≥ 20 cm) for longer periods (> 6 weeks) had more problems with encrustation and migration. AUTHORS' CONCLUSIONS Routine prophylactic stenting reduces the incidence of MUCs. Studies comparing selective stenting and universal prophylactic stenting, whilst difficult to design and analyse, would address the unresolved quality of life and economic issues.

Abstract
AIM The incidence of urologic complications after renal transplantation has been reported to be between 2.5% and 27%. The aim of this study was to evaluate urologic complications of and their surgical treatment in our series of renal transplantations. MATERIALS AND METHODS We retrospectively evaluated urologic complications among 395 renal transplant recipients in our institute. RESULTS The urologic complications were ureteral leakage (n = 8), stricture of ureteral anastomosis (n = 3), hydronephrosis secondary to stone (n = 2) and bladder outlet obstruction (n = 2), recurrent urinary infection because of vesicoureteral reflux to native kidney (n = 2), renal tumor in native kidney (n = 1), hydroceles (n = 3), technical complications (n = 2), and clot retention (n = 1). CONCLUSION Major urologic complications following renal transplantation are ureteral leakage and stricture resulting from disrupture of the distal ureteral blood supply during the donor operation. Extravesical ureteroneocystostomy over a JJ stent seems feasible to minimize urologic complication. Early diagnosis and endourologic techniques are the mainstays of treatment.

Abstract
PURPOSE We compared the incidence of ureteral complications between the classic (Lich-Gregoir) technique and the recently popularized single stitch (Shanfield) technique in renal transplantation. MATERIALS AND METHODS The charts of 721 consecutive transplant recipients from May 1999 to July 2002 were retrospectively reviewed. Ureteral and nonureteral complications were reviewed at 3 to 5-year followup. RESULTS Of the 721 recipients evaluated 713 were included in the study. There were 360 recipients in the Lich-Gregoir group and 353 in the Shanfield group. A significantly higher rate of ureteral complications occurred in the Shanfield group compared to the Lich-Gregoir group (15.6% vs 3.9%, p <0.0001). The Shanfield group consisted of 20 patients with ureteral leakage, 21 with hematuria, 11 with strictures and 3 who had ureteral stones. The Lich-Gregoir group had 8 patients with ureteral leakage, 5 with hematuria and 1 with a stricture. In comparison, urinary tract infections, delayed graft function and rejection rates were not significantly different between the 2 groups (p = 0.76, 0.12 and 0.19, respectively). CONCLUSIONS In contrast to other reports, the Shanfield group had significantly more ureteral complications. In particular the Shanfield technique may predispose patients to higher rates of hematuria and stone formation. Based on this large series and published meta-analyses we believe that the stented Lich-Gregoir anastomosis is the superior ureteroneocystostomy technique in renal transplantation.

Abstract
Taguchi technique of ureteral implantation was used in 22 kidney transplant patients (group T). Group T was compared with 25 patients who were treated using Lich-Gregoir technique (group LG). Immunosuppression, incidence of biopsy evidenced acute cellular rejection (ACR), haematuria rate and ureteral complications (stricture, reflux) were assessed in both groups. The immunosuppression used was based on cyclosporin A (63.6%), tacrolimus (27.3%) and sirolimus (8.1%) in T group. Cyclosporin A(72%), tacrolimus (20%) and sirolimus (8%) were used in LG group. No induction was used. The incidence of ACR was similar in both groups--T resp. LG was 50% resp. 52%. Haematuria after operation was on average 4.0 days in the T group and on average 3.1 in the LG group. Ureteral complications were observed in 18.2% of cases in T group and in 16% of cases in LG group. No reflux was evidenced in any group. Taguchi technique is fast and very easy to do. A slightly higher incidence of ureteralcomplications and a longer period of postoperative haematuria were observed in T group. Taguchi technique is very easily performed with a shorter operating time. We advocate it as a method of ureteral implantation on the thin-wall urinary bladder. The results were very good in these cases.

Abstract
BACKGROUND Major urological complications (MUCs) after kidney transplantation contribute to patient morbidity and compromise graft function. The majority arise from the vesico-ureteric anastomosis and present early after transplantation. Ureteric stents have been successfully used to treat such complications. A number of centres have adopted a policy of universal prophylactic stenting, at the time of graft implantation, to reduce the incidence of urine leaks and ureteric stenosis. Stents are associated with specific complications and some centres advocate a policy of only stenting selected anastomoses. OBJECTIVES To examine the benefits and harms of routine ureteric stenting to prevent urological complications in kidney transplant recipients. SEARCH STRATEGY We searched the Cochrane Central Register of Controlled Trials (CENTRAL in The Cochrane Library), MEDLINE, EMBASE, reference lists of articles, books and abstracts and contacted companies, authors and experts to identify relevant randomised controlled trials (RCTs). SELECTION CRITERIA All RCTs and quasi-RCTs were included in our meta-analysis. DATA COLLECTION AND ANALYSIS Four reviewers assessed the trials for quality against four criteria (allocation concealment, blinding, intention-to-treat and completeness of follow-up). The primary outcome was the incidence of MUCs. Further outcomes of interest were graft and patient survival and the incidence of adverse events (urinary tract infection (UTI), haematuria, irritative symptoms, pain and stent migration). Statistical analyses were performed using the random effects model and the results expressed as relative risk (RR) with 95% confidence intervals (CI). MAIN RESULTS Seven RCTs (1154 patients) of low or moderate quality were identified. The incidence of MUCs was significantly reduced (RR 0.24, 95% CI 0.07 to 0.77, P = 0.02, NNT 13) by universal prophylactic stenting. This was dependent on whether the same surgeon performed, or was in attendance, during the operations. Two patients lost their grafts to infective urinary tract complications in the stented group. UTIs, in general, were more common in stented patients (RR 1.49, 95% CI 1.04 to 2.15) unless the patients were prescribed cotrimoxazole 480 mg/d: in which case the incidence was equivalent (RR 0.97, 95% CI 0.71 to 1.33). Stents appeared generally well tolerated, although trials using longer stents (>/= 20 cm) for longer periods (> 6 weeks) had more problems with encrustation and migration. AUTHORS' CONCLUSIONS Routine prophylactic stenting reduces the incidence of MUCs. Trials comparing selective stenting and universal prophylactic stenting, whilst difficult to design and analyse, would address the unresolved quality of life and economic issues.
