Sexual function after pelvic organ prolapse surgery: a systematic review comparing different approaches to pelvic floor repair.

OBJECTIVE: Women consider preservation of sexual activity and improvement of sexual function as important goals after pelvic organ prolapse surgery. This systematic review aimed to compare sexual activity and function before and after prolapse surgery among specific approaches to pelvic organ prolapse surgery including native tissue repairs, transvaginal synthetic mesh, biologic grafts, and sacrocolpopexy. DATA SOURCES: MEDLINE, Embase, and ClinicalTrials.gov databases were searched from inception to March 2021. STUDY ELIGIBILITY CRITERIA: Prospective comparative cohort and randomized studies of pelvic organ prolapse surgeries were included that reported the following specific sexual function outcomes: baseline and postoperative sexual activity, dyspareunia, and validated sexual function questionnaire scores. Notably, the following 4 comparisons were made: transvaginal synthetic mesh vs native tissue repairs, sacrocolpopexy vs native tissue repairs, transvaginal synthetic mesh vs sacrocolpopexy, and biologic graft vs native tissue repairs. METHODS: Studies were double screened for inclusion and extracted for population characteristics, sexual function outcomes, and methodological quality. Evidence profiles were generated for each surgery comparison by grading quality of evidence for each outcome across studies using a modified Grading of Recommendations Assessment, Development and Evaluation (GRADE) system. RESULTS: Screening of 3651 abstracts was performed and identified 77 original studies. The overall quality of evidence was moderate to high. There were 26 studies comparing transvaginal synthetic mesh with native tissue repairs, 5 comparing sacrocolpopexy with native tissue repairs, 5 comparing transvaginal synthetic mesh with sacrocolpopexy, and 7 comparing biologic graft with native tissue repairs. For transvaginal synthetic mesh vs native tissue repairs, no statistical differences were found in baseline or postoperative sexual activity, baseline or postoperative total dyspareunia, persistent dyspareunia, and de novo dyspareunia. Pelvic Organ Prolapse/Urinary Incontinence Sexual Questionnaire short form change scores were not different between transvaginal synthetic mesh and native tissue repairs (net difference, -0.3; 95% confidence interval, -1.4 to 0.8). For sacrocolpopexy vs native tissue repairs, baseline or postoperative sexual activity, baseline or postoperative total dyspareunia, de novo dyspareunia, and Pelvic Organ Prolapse/Urinary Incontinence Sexual Questionnaire short form score differences were not different. For biologic graft vs native tissue repairs, baseline or postoperative sexual activity, baseline or postoperative total dyspareunia, and Pelvic Organ Prolapse/Urinary Incontinence Sexual Questionnaire short form changes were also not different. For transvaginal synthetic mesh vs sacrocolpopexy, there was no difference in sexual activity and sexual function score change. Based on 2 studies, postoperative total dyspareunia was more common in transvaginal synthetic mesh than sacrocolpopexy (27.5% vs 12.2%; odds ratio, 2.72; 95% confidence interval, 1.33-5.58). The prevalence of postoperative dyspareunia was lower than preoperative dyspareunia after all surgery types. CONCLUSION: Sexual function comparisons are most robust between transvaginal synthetic mesh and native tissue repairs and show similar prevalence of sexual activity, de novo dyspareunia, and sexual function scores. Total dyspareunia is higher after transvaginal synthetic mesh than sacrocolpopexy. Although sexual function data are sparse in the other comparisons, no other differences in sexual activity, dyspareunia, and sexual function score change were found.

Changes in Sexual Activity and Function After Pelvic Organ Prolapse Surgery: A Systematic Review.

OBJECTIVE: We aimed to systematically review the literature to describe sexual activity and function before and after prolapse surgery. DATA SOURCES: We searched MEDLINE, EMBASE, and ClinicalTrials.gov databases from inception to April 2018. METHODS OF STUDY SELECTION: Prospective, comparative studies of reconstructive pelvic organ prolapse (POP) surgeries that reported sexual function outcomes were included. Studies were extracted for population characteristics, sexual function outcomes, and methodologic quality. Data collected included baseline and postoperative sexual activity, dyspareunia, and validated sexual function questionnaire scores. Change in validated scores were used to categorize overall sexual function as improved, unchanged, or worsened after surgery. TABULATION, INTEGRATION, AND RESULTS: The search revealed 3,124 abstracts and identified 74 articles representing 67 original studies. The overall quality of evidence was moderate to high. Studies reporting postoperative results found higher rates of sexual activity than studies reporting preoperative sexual activity in all POP surgeries except sacrospinous suspension, transvaginal mesh, and sacrocolpopexy. The prevalence of dyspareunia decreased after all prolapse surgery types. The risk of de novo dyspareunia ranged from 0% to 9% for all POP surgeries except posterior repair, which lacked sufficient data. Overall sexual function based on PISQ-12 (Pelvic Organ Prolapse/Incontinence Sexual Questionnaire-12) scores improved for mixed native tissue repairs, anterior repairs, uterosacral suspensions, sacrospinous suspensions, and sacrocolpopexy; scores were similar for posterior repairs, transvaginal mesh, and biologic grafts. Sexual function did not worsen after any POP surgeries. CONCLUSION: Sexual function improves or remains unchanged after all types of reconstructive POP surgeries and does not worsen for any surgery type. Prevalence of total dyspareunia was lower after all POP surgery types, and de novo dyspareunia was low ranging 0-9%. This information can help surgeons counsel patients preoperatively.

Frequency of the Original Kidney Disease and Its Effect on the Outcome of Kidney Transplant in the Urology-Nephrology Center Mansoura University.

OBJECTIVES: Renal allograft function and graft survival depends on many factors, including the source of the graft, immunologic matching between donor and recipient, incidence of acute rejection, and recurrence of the original kidney disease. This work aimed to evaluate the effects of the original kidney disease on patient and graft survival. MATERIALS AND METHODS: This was a retrospective, single-center study that included 2189 kidney transplant recipients who were transplanted at The Urology and Nephrology Centre, Mansoura University, between 1976 and 2010. Of 2189 recipients, 1350 patients with unknown original kidney disease were excluded, with the remaining 839 patients divided into 4 groups according to their original kidney disease. RESULTS: We found pretransplant dialysis and blood transfusion to be statistically significant among the 4 groups. Regarding induction immunosuppressive therapy, a statistical significance was found between the 4 groups regarding the presence and type of induction therapy, with no statistical significance regarding the type of maintenance immunosuppression. There was no statistical significance between the 4 groups regarding the incidence of acute and chronic rejection. We also found recurrence of original kidney disease to be statistically significant in the 4 groups, particularly in the group that included patients with glomerular disease, where the highest rate of recurrence was reported in patients with focal segmental glomerulosclerosis and membranoproliferative glomerulonephritis, and patient and graft survival was also statistically significant. CONCLUSIONS: The original kidney disease has an effect on renal allograft function and graft and patient survival.

Preemptive living-donor kidney transplantation: clinical course and outcome.

BACKGROUND: Dialysis is not only associated with morbidity, it is also expensive. In developing countries, preemptive renal transplantation (Tx) may be a cost-effective option, offering an additional benefit to conventional renal Tx. MATERIALS: Between March 1976 and March 2001, 1,279 first living-donor Txs were performed in our center. The 82 patients (6.4%) who underwent Tx without prior dialysis were compared with 1,197 patients who had been dialyzed before Tx. RESULTS: The dialysis-dependent group received more blood transfusions (65% vs. 30%) before Tx. Actuarial graft and patient survival at 5 years was comparable in both groups (P =0.2 and P =0.8, respectively). The incidence of acute and chronic rejection was not different between the two groups. Mortality rate was also similar in the two groups. The main cause of death with a functioning graft was cardiovascular in the preemptive Tx group and chronic liver disease and infection in the control group. CONCLUSION: In the context of a developing country, preemptive Tx offers comparable patient and graft survival to conventional renal Tx and eliminates the complications, inconvenience, and cost of dialysis.

Characteristics of long-term live-donor pediatric renal transplant survivors: a single-center experience.

OBJECTIVES: To study the characteristics and the predictors of survival observed in our pediatric live-donor renal transplant recipients with an allograft that functioned for more than 10 yr. METHODS: One hundred fifteen children underwent renal transplantation between 1976 and 1995. Of these, 30 had functioning allografts for more than 10 yr (range, 11-18). The patients included 18 males and 12 females, with a mean age at transplantation of 13 yr (range, 5-18). Characteristics of the patients, data on graft survival, and determinants of outcome were obtained by reviewing all medical charts. RESULTS: At most recent follow-up (January 2005), the mean daily dose of azathioprine was 1.2 mg/kg (range, 1-2) and that of prednisone was 0.16 mg/kg (range, 0.1-0.2). Mean creatinine clearance was 72 mL/min per 1.73 m(2) (range, 45-112). Acute rejection occurred in 14 (47%) patients. Seven patients had one episode, five had two episodes, and two had three episodes of acute rejection. Three patients (10%) developed malignancy. A substantial proportion of patients (44%) were short, with a height standard deviation score (SDS) less than -1.88, which is below the third percentile for age and gender. One quarter of the patients, more commonly the females, were obese. Other complications included osteoporosis in 16 (53%) patients, avascular bone necrosis in four (13%), post-transplantation diabetes mellitus in three (10%), and hypertension in 18 (60%). Twelve (40%) patients were married and 27% had children post-transplantation. The independent determinants of long-term graft survival were acute rejection and post-transplant hypertension. CONCLUSION: Despite good renal function, long-term pediatric renal transplant survivors are at risk of significant morbidity. The determinants of long-term graft survival are acute rejection and post-transplant hypertension.

Pediatric live-donor kidney transplantation in Mansoura Urology & Nephrology Center: a 28-year perspective.

Our objective was to evaluate our overall experience in pediatric renal transplantation. Between March 1976 and March 2004, 1,600 live-donor kidney transplantations were carried out in our center; 216 of the patients were 18 years old or younger (mean age 12.9 years). There were 136 male patients and 80 female patients. The commonest causes of end-stage renal disease (ESRD) were renal dysplasia (22%), nephrotic syndrome (20%), hereditary nephritis (16%), and obstructive uropathy (16%). Of the donors, 94% were one-haplotype matched and the rest were identical. Pre-emptive transplantation was performed in 51 (23%) patients. Triple-therapy immunosuppression (prednisone + cyclosporine + azathioprine) was used in 78.2% of transplants. Rejection-free recipients constituted 47.7%. Hypertension (62%) was the commonest complication. A substantial proportion of patients (48%) were short, with height standard deviation score (SDS) less than -1.88. The overall infection rate was high, and the majority (53%) of infections were bacterial. The graft survival at 1 year, 5 years and 10 years were 93.4%, 73.3% and 48.2%, respectively, while the patients' survival at 1, 5 and 10 years were 97.6%, 87.8% and 75.3%, respectively. Despite long-term success results of pediatric renal transplantation in a developing country, there is a risk of significant morbidity.

Determinants of graft survival in pediatric and adolescent live donor kidney transplant recipients: a single center experience.

To study the independent determinants of graft survival among pediatric and adolescent live donor kidney transplant recipients. Between March 1976 and March 2004, 1600 live donor kidney transplants were carried out in our center. Of them 284 were 20 yr old or younger (mean age 13.1 yr, ranging from 5 to 20 yr). Evaluation of the possible variables that may affect graft survival were carried out using univariate and multivariate analyses. Studied factors included age, gender, relation between donor and recipient, original kidney disease, ABO blood group, pretransplant blood transfusion, human leukocyte antigen (HLA) matching, pretransplant dialysis, height standard deviation score (SDS), pretransplant hypertension, cold ischemia time, number of renal arteries, ureteral anastomosis, time to diuresis, time of transplantation, occurrence of acute tubular necrosis (ATN), primary and secondary immunosuppression, total dose of steroids in the first 3 months, development of acute rejection and post-transplant hypertension. Using univariate analysis, the significant predictors for graft survival were HLA matching, type of primary urinary recontinuity, time to diuresis, ATN, acute rejection and post-transplant hypertension. The multivariate analysis restricted the significance to acute rejection and post-transplant hypertension. The independent determinants of graft survival in live-donor pediatric and adolescent renal transplant recipients are acute rejection and post-transplant hypertension.

Effect of donor/recipient body weight mismatch on patient and graft outcome in living-donor kidney transplantation.

BACKGROUND/AIMS: There have been conflicting reports showing that kidneys from small donors may be at risk for graft loss if they are transplanted into large recipients. The aim of this work was to examine the donor/recipient body weight ratio (D/RBWR) on patient and graft outcome. METHODS: During the period from January 1990 to January 2002, 856 kidney transplants were performed. Of these, 776 kidney transplant recipients were selected after exclusion of pediatric, second transplant patients and those with a body mass index of 35. All patients achieved a minimum follow-up of 1-year. According to D/RBWR, patients were divided into 3 groups: low (0.9), medium (0.91-1.2) and high (1.2). Data were collected on graft function, acute and chronic rejection, post-transplant complications, and 1- and 5-year graft and patient survival. RESULTS: There was a statistically significant increase in the incidence of chronic rejection, post-transplant hypertension and diabetes mellitus in the low group. The incidence and frequency of acute rejection episodes were nearly the same in the 3 groups. Graft function, estimated by serum creatinine at 1 year, was significantly lower in the low group. The 5-year graft and patient survival was 71, 80, 88 and 81, 85 and 92%, in the low, medium and high groups, respectively. CONCLUSIONS: We conclude that a low D/RBWR may contribute to inferior long-term renal allograft survival. The hyperfiltration hypothesis due to low nephron mass in the low D/RBWR group may explain these findings.

Effect of angiotensin II receptor blocker on plasma levels of TGF-beta 1 and interstitial fibrosis in hypertensive kidney transplant patients.

BACKGROUND/AIM: Transforming growth factor-beta1 (TGF-beta 1) is involved in the pathogenesis of chronic allograft nephropathy after kidney transplantation. The aim of the study was to evaluate the effect of the angiotensin receptor blocker losartan on TGF-beta 1 plasma levels and proteinuria in hypertensive transplant recipients. METHODS: A total of 162 transplant recipients were included in the study. The patients were randomized into 3 groups: group 1 received losartan; group II received an angiotensin-converting enzyme inhibitor (captopril), and group III received a calcium channel blocker (amlodipine). All the parameters were recorded at the time of therapy initiation and at 1, 4 and 12 weeks and 12 months thereafter. Graft biopsy before the start and at the end of the study was done to evaluate histopathological progression. RESULTS: Blood pressure was controlled in the 3 groups; however, the need for other antihypertensive agents was significant in groups I and II. Treatment with losartan significantly decreased the plasma level of TGF-beta1, 24-hour urinary protein and serum uric acid (p < 0.05). No significant changes were seen in the hemoglobin or serum potassium levels. The rate of histopathological progression was significantly lower in the losartan group. No patient was discharged from the study due to side effects. CONCLUSIONS: After transplantation all drugs were able to control blood pressure with good safety and tolerability. The study demonstrates that ARB significantly decreases the plasma levels of TGF-beta1, proteinuria and uric acid. These results could play an important and decisive role in the treatment and prevention of chronic allograft nephropathy.
