Nerve-Sparing Radical Cystectomy and Orthotopic Bladder Replacement in Female Patients

Functional Outcomes of Orthotopic Neobladder in Women

PURPOSE OF REVIEW

This review paper summarizes the available literature on the evolution of surgical approach to radical cystectomy in female bladder cancer patients and its impact on functional outcomes in orthotopic neobladder.

RECENT FINDINGS

Traditionally, radical cystectomy in female bladder cancer patients has been maximally extirpative with pelvic exenteration. Recently, new techniques which include pelvic organ-sparing, nerve-sparing and vaginal-sparing have demonstrated improved rates of urinary incontinence and retention. Additional techniques include prophylactic apical suspension which reduces the likelihood of pelvic organ prolapse, a risk factor for voiding dysfunction in the setting of orthotopic neobladder. Surgical management of bladder cancer in female patients has evolved to include surgical approaches which center quality of life and functional outcomes that are unique to female patients who have undergone radical cystectomy with ileal neobladder and can be optimized based on considerations regarding an approach that limits pelvic floor and pelvic nerve disruption.

Robot-assisted radical cystectomy with neobladder diversion in females: Safety profile and functional outcomes

Objective

Radical cystectomy (RC) is a standard treatment for localized muscle invasive bladder cancer and high-risk or very high-risk non-muscle invasive bladder cancer not responding to adequate endovesical therapy. In women, traditionally RC is performed with hystero-adnexectomy and resection of the anterior vaginal wall, often resulting in sexual disorders. Vaginal-sparing techniques have been developed to improve functional outcomes. The present study explores the safety and the functional outcome of vaginal-sparing techniques.

Methods

We retrospectively analyzed all consecutive female patients undergoing robot-assisted RC (RARC) with neobladder diversion between October 2017 and February 2022. The indications for vaginal-sparing RC were absence of tumor on bladder neck or urethra and no sign of infiltration of posterior bladder wall at the preoperative MRI. Functional results were evaluated with the aid of five questions out of the Bladder Cancer Index questionnaire. Complications were reported according to the Clavien-Dindo classification and cancer control was evaluated by recurrence-free and cancer-specific survival.

Results

A total of 22 female patients underwent RARC with neobladder diversion. Neoadjuvant chemotherapy was given in 17 (77%) cases. Clavien-Dindo grades III-IV complications occurred in four (18%) cases. After a mean follow-up of 29 (interquartile range 16-44) months, six (27.3%) patients developed distant metastases, and one (4.5%) woman loco-regional relapse. Sexual-sparing surgery was performed in 19 (86%) patients, and in the others the anterior vaginal wall was resected, but neobladder was still performed. During daytime, no patients reported total incontinence and 73% (11/15) reported total continence or only occasional leaks. Sexual results showed that seven of 15 (47%) women regained sexual activity after surgery, with a quality reported as "good" or "very good" in 40% of all 19 cases.

Conclusion

RARC in female with anterior vaginal wall preservation is feasible. The approach showed a good safety profile, with satisfying results on continence and sexual activity. Sexual-sparing approaches should be carried out after correct patient selection.

Comparative evaluation of reproductive organ-preserving versus standard radical cystectomy in female: a meta-analysis and systematic review of perioperative, oncological, and functional outcomes

BACKGROUND

To evaluate the perioperative, oncological, and functional outcomes of reproductive organ-preserving radical cystectomy (ROPRC) compared to standard radical cystectomy (SRC) in the treatment of female bladder cancer.

METHODS

A systematic search was conducted in November 2023 across several scientific databases. We executed a systematic review and cumulative meta-analysis of the primary outcomes of interest, adhering to the PRISMA and AMSTAR guidelines. The study was registered in PROSPERO (CRD42024501522).

RESULTS

The meta-analysis included 10 studies with a total of 2015 participants. ROPRC showed a significant reduction in operative time and postoperative fasting period compared to SRC (MD - 45.69, 95% CI - 78.91 ~ - 12.47, p = 0.007, and MD - 0.69, 95% CI - 1.25 ~ - 0.13, p = 0.02, respectively). Functional outcomes, both daytime continence rate (OR 4.94, 95% CI 1.53 ~ 15.91, p = 0.008) and nighttime continence rate (OR 5.91, 95% CI 1.94 ~ 18.01, p = 0.002), and sexual function measured by the Female Sexual Function Index (MD 5.72, 95% CI 0.19 ~ 11.26, p = 0.04), were significantly improved in the ROPRC group. There were no significant differences between ROPRC and SRC in terms of estimated blood loss, length of hospital stay, overall postoperative complications, minor complications or major complications. Oncologically, both procedures showed comparable outcomes with no significant differences in positive surgical margins, tumor recurrence rates, overall survival, cancer-specific survival, recurrence-free survival, or progression-free survival.

CONCLUSIONS

ROPRC is a viable and effective alternative to SRC in female bladder cancer patients, offering enhanced functional outcomes and similar oncological safety. These findings suggest that ROPRC can improve the quality of life in female bladder cancer patients without compromising the efficacy of cancer treatment.

Long-term survival after female pelvic organ-sparing radical cystectomy versus standard radical cystectomy: a multi-institutional propensity score-matched analysis

BACKGROUND

The application of pelvic organ preserving-radical cystectomy (POPRC) in female patients with bladder cancer has attracted more and more attention in recent years. In the current study, the authors aim to compare the long-term oncological outcomes of POPRC versus standard radical cystectomy (SRC) in a large multicenter retrospective cohort.

PATIENTS AND METHODS

Data on female patients with bladder cancer who underwent POPRC or SRC in January 2006 and April 2018 were included from three Chinese urological centers. The primary outcome was overall survival (OS). Secondary outcomes were cancer-specific survival and recurrence-free survival. To decrease the effect of unmeasured confounders associated with treatment selection, 1:1 propensity score matching was performed.

RESULTS

Among the 273 enrolled patients, 158 underwent POPRC (57.9%), and 115 underwent SRC (42.1%). The median follow-up time was 38.6 (15.9-62.5) months. After propensity score matching, each cohort included 99 matched patients. The OS ( P =0.940), cancer-specific survival ( P =0.957), and recurrence-free survival ( P =0.476) did not differ significantly from the two matched cohorts. Subgroup analysis confirmed that the OS was similar between the patients treated with POPRC and SRC across all subgroups examined (all P > 0.05). In multivariable analysis, the surgical method (SRC vs. POPRC) was not an independent risk factor for OS (Hazard ratio 0.874, 95% CI 0.592-1.290; P =0.498).

CONCLUSIONS

The results showed that no significant difference in long-term survival was determined between female patients undergoing SRC and those undergoing POPRC.

Practice Patterns Regarding Female Reproductive Organ-Sparing and Nerve-Sparing Radical Cystectomy Among Urologic Oncologists in the United States

BACKGROUND

Female reproductive organ-sparing (ROS) and nerve-sparing radical cystectomy (RC) techniques have been shown to be oncologically safe and to improve sexual function outcomes among select patients with organ-confined disease. We sought to characterize practice patterns regarding female ROS and nerve-sparing RC among US urologists.

PATIENTS AND METHODS

We conducted a cross-sectional survey of members of the Society of Urologic Oncology to assess provider-reported frequency of ROS and nerve-sparing RC in premenopausal and postmenopausal patients with non-muscle-invasive bladder cancer that failed intravesical therapy or clinically localized muscle-invasive bladder cancer.

RESULTS

Among 101 urologists, 80 (79.2%) reported that they routinely resect the uterus/cervix, 68 (67.3%) the neurovascular bundle, 49 (48.5%) the ovaries, and 19 (18.8%) a portion of the vagina when performing RC in premenopausal patients with organ-confined disease. When asked about changes to approach in postmenopausal patients, 71 participants (70.3%) reported that they were less likely to spare the uterus/cervix, 44 (43.6%) were less likely to spare the neurovascular bundle, 70 (69.3%) were less likely to spare the ovaries, and 23 (22.8%) were less likely to spare a portion of the vagina.

CONCLUSION

We identified significant gaps in adoption of female ROS and nerve-sparing RC techniques for patients with organ-confined disease, despite evidence that ROS and nerve-sparing techniques are oncologically safe and can optimize functional outcomes in select patients. Future efforts should improve provider training in and education about ROS and nerve-sparing RC to improve postoperative outcomes among female patients.

Pregnancy after sexuality preserving cystectomy with urinary diversion for bladder cancer: case report and review of the literature

Background

Radical cystectomy for bladder cancer represents a high demolitive surgical procedure with a significative impact on quality of life. Sexuality preserving techniques have been proposed in order to improve functional outcomes. Although sex-sparing techniques would provide women with the chance of having pregnancy, experience is still limited when malignant conditions are considered. We report the outcomes of pregnancy and delivery in a 43-year-old woman with a Padua ileal orthotopic neobladder after robot-assisted sexuality preserving cystectomy for muscle-invasive urothelial bladder cancer performed four years earlier, at age 39.

Case presentation

Since pregnancy was confirmed, the patient had been under close urological and gynecological observation. Hydronephrosis and voiding-relating complications were reported and treated by inserting a nephrostomy tubes and indwelling bladder catheter. At the time of delivery, elective caesarian section was performed without complications.

Conclusions

Sexuality preserving cystectomy could be an option in selected and highly motivated young patients with diagnosis of bladder cancer. A multidisciplinary team of experts included gynecologists, urologists, radiologists, anesthesiologists and neonatologists is required for the optimal management of pregnancy and peripartum care in women with urinary diversion.

Cystectomy for Benign Indications

PURPOSE OF REVIEW

This article evaluates the historical influences, current use, surgical techniques, and recent evidence on outcomes for cystectomy performed for benign indications.

RECENT FINDINGS

At the population level, cystectomy for benign indications has similar perioperative morbidity to radical cystectomy for cancer. Postoperative patient satisfaction is high and functional outcomes appear good, including sexual function. Patient regret about diversion choice is low provided decisions are well informed. Cystectomy is important both as a primary procedure for benign disease and as an adjunct to primary urinary diversion. Early morbidity remains high but long-term results are encouraging. Further studies are needed to guide patient decision-making, to help inform diversion choice, and to understand the long-term impact of surgery and diversion choice on quality of life.

Radical cystectomy and women's sexual health - can we do better?

PURPOSE OF REVIEW

Female sexual function after radical cystectomy is a crucial, but historically overlooked component of bladder cancer survivorship. This review focuses on recent studies, which have investigated pelvic health and sexual function after radical cystectomy. We discuss modifiable factors, which may contribute to decreased sexual function after radical cystectomy and techniques, which may lead to improved outcomes.

RECENT FINDINGS

Sexual function is important to women and there is a significant desire (and unmet need) for more perioperative counseling and discussion regarding sexual function changes and quality of life impacts. Sexual function may be altered due to a combination of hormonal changes from ovarian removal, anatomic changes from vaginal alteration, and sensation changes due to damage to the neurovascular bundle. Techniques to preserve these structures have been developed.

SUMMARY

Sexual function is an important component of survivorship and increasing attention is being focused on this area. Long term studies with objective measures are needed for to compare various techniques and ensure oncologic safety. Ovarian preservation, anterior vaginal wall preservation, and vaginal estrogen replacement should be carefully considered for most patients.

Gender-related outcomes in robot-assisted radical cystectomy: A multi-institutional study

PURPOSE

Robot-assisted radical cystectomy (RARC) optimizes patient recovery and has outcomes comparable with those of open surgery. This study aimed to compare the perioperative and oncologic outcomes of RARC in female and male patients.

MATERIALS AND METHODS

A retrospective cohort study of the Korean Robot-Assisted Radical Cystectomy Study Group database from 2007 to 2019 identified 749 patients (111 females and 638 males). Female were matched 1:1 to male by propensity score matching using a logistic regression. We compared perioperative outcomes, oncologic outcomes, and complications between the two groups.

RESULTS

The female group had comparable perioperative outcomes to the male group in terms of operation time, lymph node yield, positive surgical margin, blood transfusion rate, and hospitalization days. Complication rate and grade were not significantly different between the two groups. The most common complication was infection in female and gastrointestinal complications in male. We compared the 5-year overall, disease-specific, and recurrence-free survival of female and male: 58.2% vs. 68.0% (p=0.495), 75.7% vs. 79.3% (p=0.645), and 40.8% vs. 53.5% (p=0.913), respectively. On multivariable analysis, T stage (>T2), postoperative complications, and positive surgical margin were prognostic factors of poor outcome. Sex was not an independent predictor of the three survivals.

CONCLUSIONS

The current study suggests that RARC in female has comparable perioperative and oncologic outcomes to those in male. The complication rate of RARC in female was comparable to that in male, but the type of complications differed by sex.

Safety and Efficacy of Reproductive Organ-Sparing Radical Cystectomy in Women With Variant Histology and Advanced Stage

PURPOSE

Muscle invasive bladder cancer surgical management has been historically a radical cystoprostatectomy in males and an anterior exenteration in females. Uterine, ovarian, and vaginal preservation are utilized, but raise concerns regarding risk to oncologic control, especially in variant histopathology or advanced stage.

MATERIALS AND METHODS

A retrospective single institutional analysis identified radical cystectomies performed in women, including those with variant histology, which were defined as reproductive organ sparing (uterine, vaginal, and ovary sparing) or nonorgan sparing. The Kaplan-Meier method was used for recurrence-free survival (RFS), cancer-specific survival (CSS), and overall survival (OS) in patients with advanced disease.

RESULTS

From 2000 to 2020, 289 women were identified, 188 underwent reproductive organ-sparing cystectomy. No statistical differences were noted for clinical parameters or presence of variant histology for organ-sparing (ROS) and nonorgan-sparing (non-ROS). Positive margin rates did not differ for ROS and non-ROS; 4.3% vs. 7.9%, P = .19, respectively. Median RFS was not statistically significantly different for ROS vs. non-ROS (26.1 vs. 15.3 months) P = .937 hazard ratio (HR) 1.024. CSS was not statistically different for ROS vs. non-ROS (36.3 vs. 28.6 months), P = .755 HR 0.9. OS was not statistically different for ROS vs. non-ROS (25.8 vs. 23.8 months), P = .5 HR = 1.178. Variant histology did not change survival (HR 1.1, P = .643).

CONCLUSION

In this analysis, ROS in women with advanced disease did not increase positive margin rates or decrease RFS, CSS, or OS compared to non-ROS. Variant histology did not decrease survival odds. Based on preoperative assessment and intraoperative findings, ROS in patients with variant histology and advanced disease should be considered.

Perioperative and Pathological Outcome of Nerve-Sparing Radical Cystectomy With Ileal Neobladder

Purpose: So far, it has not been described whether the perioperative course and the pathologic outcome of patients who undergo radical cystectomy (RC) with orthotopic bladder substitution differs if nerve sparing (NS) is performed or not. Material and Methods: In all, there were 472 patients who underwent RC between 2012 and 2019 at our department. We performed a retrospective analysis of 116 patients who underwent RC with ileal neobladder. We analyzed perioperative complications according to the Clavien-Dindo classification system, as well as the pathological outcome. Results: Of 116 patients, 68 (58.6%) underwent RC, and 48 (41.4%) underwent NS RC. Clavien-Dindo complications ≥3b occurred in 15 (12.9%) of all patients. Only infectious complications differed among the groups [NS RC: 25 patients (52.1%) vs. RC: 20 patients (29.4%); p = 0.02]. There was no significant difference concerning tumor stage. Concomitant Cis was present in 24 patients (35.3%) of the RC group and in 27 patients (56.3%) of the NS RC group (p = 0.036). Nodal status and positive surgical margin status of the bladder tumor did not differ among the groups. In all, 42 of all male patients (45.7%) had an incidental prostatic carcinoma. Positive surgical margins concerning the prostate carcinoma occurred in six patients, with all cases in the RC group (p = 0.029). Conclusions: Our data suggest that performing NS during RC in carefully selected patients is a safe procedure and does not impair perioperative outcome. Pathological outcome of NS RC is comparable as well.

Functional outcomes after robot-assisted radical cystectomy: A review of literature

Robot-assisted radical cystectomy has steadily gained wider acceptance among urologists compared with open and laparoscopic approaches. Robot-assisted radical cystectomy has shown comparable perioperative and oncologic outcomes compared with open radical cystectomy. Nevertheless, data about the functional outcomes and quality of life after robot-assisted radical cystectomy remain limited. We sought to review the literature and describe urinary, sexual and bowel functions after robot-assisted radical cystectomy in addition to mental health and health-related quality of life. Despite limitations of the available literature, data suggests that functional outcomes after robot-assisted radical cystectomy are comparable to open radical cystectomy. However, more studies utilizing standardized definitions are required.

Histologic Investigation of the Female Vesicourethral Junction and Adjacent Tissues for Nerve-sparing Radical Cystectomy

OBJECTIVE

To understand the structures around the vesicourethral junction and to improve functional outcomes after nerve-sparing radical cystectomy with orthotopic urinary diversion for female patients, we histologically elucidated the fibromuscular construction and nerve distribution around the vesicourethral junction.

METHODS

Pelvic specimens containing all the pelvic viscera were obtained from 33 donated female cadavers. Macroslices that included the urethra, the anterior wall of the vagina, and the inferomedial edge of the levator ani muscle were made and performed elastica Masson and immunohistochemical staining. The intraoperative findings were collected in 3 female patients undergoing nerve-sparing radical cystectomy.

RESULTS

In 18 out of the 33 cadavers, smooth muscle mass occupied a space between the urethra and the inferomedial edge of the levator ani muscle and covered the inferior margin of the bladder detrusor. We termed this mass the hiatal smooth muscle. The detrusor nerves entered the bladder, and the cavernous and sphincter nerves ran between the hiatal smooth muscle and vesicourethral junction. The boundary between hiatal smooth muscle and urethral smooth muscle was easily distinguished intraoperatively during dissection of the vesicourethral junction.

CONCLUSION

We found that more than half of elderly women have hiatal smooth muscle between the urethra and inferior edge of the levator ani. Autonomic nerve fibers innervating the urethral sphincter, run between the hiatal smooth muscle and vesicourethral junction in female cadavers with hiatal smooth muscle. When performing female radical cystectomy before neobladder reconstruction, nerve sparing can be reliably performed using the hiatal smooth muscle as a landmark.

Round ligament suspending treatment in orthotopic ileal-neobladder after radical cystectomy in women: a single-centre prospective randomised trial

OBJECTIVES

To compare the occurrence of emptying dysfunction between surgical techniques for orthotopic neobladder suspended with round ligament (rONB) and the standard procedure (sONB).

PATIENTS AND METHODS

A prospective randomised controlled trial was performed in a single centre of female patients undergoing creation of an ONB using rONB or sONB. Patients were followed for ≥24 months after ONB. The primary endpoints were significant post-void residual urine volume (sPVR) and need for clean intermittent catheterisation (CIC) at 24 months postoperatively. The secondary endpoints included early and late complications, urodynamic profile, and ONB continence.

RESULTS

Between January 2011 and October 2017, the trial enrolled 85 patients, of whom 82 were randomised. A total of 41 patients had a rONB and 41 a sONB. At 24 months, 17 of the 37 patients with a sONB and nine of the 39 patients with a rONB had a sPVR. The cumulative risk of a sPVR was significantly lower in the rONB group (23.1%) vs the sONB group (45.9%) (hazard ratio [HR] 0.43, 95% confidence interval [CI], 0.19-0.96; P = 0.040). In all, 15 of the 37 patients with a sONB and four of the 39 patients with a rONB needed CIC. The cumulative risk of requiring CIC was significantly lower in the rONB group (10.3%) vs the sONB group (40.5%) (HR 0.22, 95% CI 0.07-0.67; P = 0.008) at 24 months. Multivariable Cox regression analysis also showed that the rONB type was an independently protective factor for sPVR and CIC. The rates of early (0-90 days) and late complication (>90 days) were 54.1% and 13.5% in the sONB group, and 64.1% and 10.3% in the rONB group, respectively. There were no significant differences in complications, urodynamic profile or ONB continence. A major limitation is the small sample size at a single centre.

CONCLUSION

Posterior support with round ligament for an ONB significantly improved the emptying of the ONB and resulted in a reduced need for CIC. The surgical modification is a feasible and safe technique without additional complication-related surgeries.

Sex-Sparing Robot-Assisted Radical Cystectomy with Intracorporeal Padua Ileal Neobladder in Female: Surgical Technique, Perioperative, Oncologic and Functional Outcomes

Our aim was to illustrate our technique of sex-sparing (SS)-robot-assisted radical cystectomy (RARC) in female patients receiving an intracorporeal neobladder (iN). From January 2013 to June 2018, 11 female patients underwent SS-RARC-iN at a single tertiary referral center. Inclusion criteria were a cT ≤ 2 N0 M0 bladder tumor at baseline imaging (CT or MRI) and an absence of tumors in the bladder neck, trigone and urethra at TURB. Baseline, perioperative, and outcomes at one year were reported. The median operative time was 255 min and the median hospital stay was seven days. Low-grade Clavien complications occurred in four patients (36.3%), while high-grade complications were not observed in any. Seven patients (63.7%) had an organ-confined disease at the pathologic specimen; nodal involvement and positive surgical margins were not detected in any of the cases. At a median follow-up of 28 months (IQR 14–51), no patients developed new onset of chronic kidney disease stage 3b. After one year, daytime and nighttime continence rates were 90.9% and 86.4% respectively. Quality of life as well as physical and emotional functioning improved significantly over time (all p ≤ 0.04), while urinary symptoms and sexual function worsened at three months with a significant recovery taking place at one year (all p ≤ 0.04). Overall, 8 out of 11 patients (72.7%) were sexually active at the 12-month evaluation. In select female patients, SS-RARC-iN is an oncologically sound procedure associated with favorable perioperative and functional outcomes.

Radical Cystectomy in Female Patients - Improving Outcomes

PURPOSE OF REVIEW

To review the methods of improving surgical, oncological, and functional outcomes in women with bladder cancer treated with radical cystectomy.

RECENT FINDINGS

Οrthotopic urinary diversion (ONB) is a safe option for well-selected women as it combines high rates of daytime and nighttime continence with exceptional oncologic outcomes. It is considered safe even for patients with limited lymph node disease and trigone involvement, as long as a preoperative biopsy of the bladder neck or an intraoperative frozen section analysis of distal urethral margin rules out malignant disease. Nerve-sparing techniques have shown promising results. For well-selected patients with early invasive disease, sparing of internal genitalia has proven to be oncologically safe. Yet, generally accepted and evidence-based oncological and functional follow-up schemes for women after radical cystectomy are still lacking. Properly designed prospective studies are needed with adequate number of participants in order to safely conclude about a broader use of pelvic organ-sparing cystectomy.

Oncologic, Perioperative Outcomes of Female Radical Cystectomy: Results from a Multicenter Study in Korea

PURPOSE

The lower incidence of bladder cancer among women has led to a lack of information on female radical cystectomy (RC). This study aimed to analyze the characteristics related with female RC in a cohort from multiple academic institutions.

MATERIALS AND METHODS

This was a retrospective review of 384 female patients who underwent RC for bladder cancer. Epidemiologic, perioperative variables including urologic referral periodwith consequent pathologic stage distributions were assessed. The changes in surgical techniques over time were illustrated. Also, we evaluated recurrence-free survival (RFS) at 2 and 5 years and overall survival (OS) at 5 years with stage-specific analyses using the Kaplan-Meier method.

RESULTS

The mean follow-up time was 35 months (interquartile rage [IQR], 9 to 55). The average time to urologic referral with initial symptoms was 5.5 (IQR, 1 to 6) months and over 20% of patients visited clinics after 6 months. In subsequent stage distributions according to referral period, T2 or higher stage distributions were abruptly increased after 1 year. Overall 2-year/5-year RFS rates were 0.72/0.57 and 5-year OS was 0.61. Notable surgical descriptions were as follows: 91% of patients underwent open RC; 80% of patients underwent an ileal conduit; and 83% of patients received anterior exenteration. However, the proportions of robotic surgery, orthotopic neobladder and organ sparing cystectomy have increased recen-tly.

CONCLUSION

We identified the general characteristics and changes in pattern of female RC. Our results also suggest that women are susceptible to delays in referral to an urologist and are at greater risk for worse prognosis.

The Comprehensive Complication Index CCI: A proposed modification to optimize short-term complication reporting after cystectomy and urinary diversion

OBJECTIVE

To optimize complication reporting in patients undergoing cystectomy and urinary diversion (UD) using the Comprehensive Complication Index (CCI). The original CCI ranging from 0 (no complications) to 100 (death) integrates all complications weighted by severity over time in a single formula. However, due to the large number of complications after cystectomy and UD, the CCI may exceed the upper limit.

METHODS

In an observational single-center cohort, 90-day postoperative complications in 1,313 consecutive patients undergoing cystectomy and UD from 2000 to 2017 were evaluated. Prospectively collected complications were graded according to the Clavien-Dindo classification (CDC). A modified Berne CCI was developed using an exponential function, which transforms the sum of the weights into a value between 0 and 100. The correlation between the Berne and original CCI values was depicted graphically. Finally, original CCI and Berne CCI values for each patient were extracted and compared. Predictive values of CCI scores for mortality or severe complications (CDC ≥IV) within 1 year postoperatively were investigated by use of multiple logistic regression analyses.

RESULTS

Overall complication rate was 82%, with CDC grade I to II in 56% and CDC grade IIIa to V in 27% respectively. Applying the original CCI, the upper limit was exceeded in 8 patients, with a maximal value of 119.1 (median 25.7 [interquartile range: 20.9-37.2]). The maximal value of the Berne CCI was 99.4 (21.2 [14.6-39.3]) for nondeath cases. The Berne CCI predicted the onset of death and severe complications between postoperative day 91 and 365 (both P <0.0001), whereas the original CCI was only predictive in interaction with other variables but not alone (P = 0.2772 and P = 0.0862, respectively).

CONCLUSION

The optimized Berne CCI depicts postoperative morbidity and burden within 90 days after cystectomy and UD without exceeding the upper index limit. It is specifically suited for longitudinal assessment of complications after cystectomy and UD taking into consideration every single complication and corresponding treatment. As the Berne CCI well predicted the onset of mortality and severe complications within 1 year postoperatively, this may allow a better preoperative patient counselling. It therefore warrants consideration for standardized reporting of complications after cystectomy and UD.

Precision surgery and genitourinary cancers

The landscape of the surgical management of urologic malignancies has dramatically changed over the past 20 years. On one side, better diagnostic and prognostic tools allowed better patient selection and more reliable surgical planning. On the other hand, the implementation of minimally invasive techniques and technologies, such as robot-assisted laparoscopy surgery and image-guided surgery, allowed minimizing surgical morbidity. Ultimately, these advances have translated into a more tailored approach to the management of urologic cancer patients. Following the paradigm of "precision medicine", contemporary urologic surgery has entered a technology-driven era of "precision surgery", which entails a range of surgical procedures tailored to combine maximal treatment efficacy with minimal impact on patient function and health related quality of life. Aim of this non-systematic review is to provide a critical analysis of the most recent advances in the field of surgical uro-oncology, and to define the current and future role of "precision surgery" in the management of genitourinary cancers.

Systematic review of the oncological and functional outcomes of pelvic organ-preserving radical cystectomy (RC) compared with standard RC in women who undergo curative surgery and orthotopic neobladder substitution for bladder cancer

CONTEXT

Pelvic organ-preserving radical cystectomy (POPRC) for women may improve postoperative sexual and urinary functions without compromising the oncological outcome compared with standard radical cystectomy (RC).

OBJECTIVE

To determine the effect of POPRC on sexual, oncological and urinary outcomes compared with RC in women who undergo standard curative surgery and orthotopic neobladder substitution for bladder cancer.

EVIDENCE ACQUISITION

Medline, Embase, Cochrane controlled trials databases and clinicaltrial.gov were systematically searched for all relevant publications. Women with bladder cancer who underwent POPRC or standard RC and orthotopic neobladder substitution with curative intent were included. Prospective and retrospective comparative studies and single-arm case series were included. The primary outcomes were sexual function at 6-12 months after surgery and oncological outcomes including disease recurrence and overall survival (OS) at >2 years. Secondary outcomes included urinary continence at 6-12 months. Risk of bias (RoB) assessment was performed using standard Cochrane review methodology including additional domains based on confounder assessment.

EVIDENCE SYNTHESIS

The searches yielded 11 941 discrete articles, of which 15 articles reporting on 15 studies recruiting a total of 874 patients were eligible for inclusion. Three papers had a matched-pair study design and the rest of the studies were mainly small, retrospective case series. Sexual outcomes were reported in seven studies with 167/194 patients (86%) having resumed sexual activity within 6 months postoperatively, with median (range) patients' sexual satisfaction score of 88.5 (80-100)%. Survival outcomes were reported in seven studies on 197 patients, with a mean follow-up of between 12 and 132 months. At 3 and 5 years, cancer-specific survival was 70-100% and OS was 65-100%. In all, 11 studies reported continence outcomes. Overall, the daytime and night-time continence rates were 58-100% and 42-100%, respectively. Overall, the self-catheterisation rate was 9.5-78%. Due to poor reporting and large heterogeneity between studies, instead of subgroup-analysis, a narrative synthesis approach was used. The overall RoB was high across all studies.

CONCLUSION

For well-selected patients, POPRC with orthotopic neobladder may potentially be comparable to standard RC for oncological outcomes, whilst improving sexual and urinary function outcomes. However, in women undergoing RC, oncological and functional data regarding POPRC remain immature and require further evaluation in a prospective comparative setting.

Management of Voiding Dysfunction After Female Neobladder Creation

PURPOSE OF REVIEW

Functional complications after orthotopic neobladder urinary diversion (ONB), including urinary incontinence and urinary retention, present unique challenges. The purpose of this review is to outline contemporary treatment options for voiding dysfunction after ONB in females.

RECENT FINDINGS

Meticulous surgical technique in the form of urethral nerve-sparing has been shown to play an important role in maintaining continence, as has sparing the uterus when possible. Data supporting the effectiveness of lifestyle measures, urethral bulking, pubovaginal slings, and transobturator slings in the treatment of urinary incontinence are widely variable and limited to case reports. Urinary retention is still most effectively managed with self-catheterization. Voiding dysfunction after ONB can be devastating. Recent advances focus on improving surgical techniques to decrease the risk of incontinence and retention, as post-operative management options are limited.

Treatment of Pelvic Floor Disorders Following Neobladder

Radical cystectomy remains the gold standard treatment for organ-confined high-grade recurrent or muscle-invasive bladder cancer. Orthotopic neobladder urinary diversion following cystectomy represents an option for patients wishing for continent urinary diversion. Female patients who undergo radical cystectomy with orthotopic bladder substitution are at risk for developing both common and neobladder-specific disorders of the pelvic floor, including urinary incontinence, hypercontinence, vaginal prolapse, and neobladder-vaginal fistula. Each of these sequelae can have significant impact on the patient's quality of life. Due to the increased frequency of orthotopic neobladder creation in women, subspecialty urologists are more likely to confront such pelvic floor disorders in bladder cancer survivors. This review presents the most current information on the treatment of pelvic floor disorders after orthotopic bladder substitution.

Impact of a Potassium-enriched, Chloride-depleted 5% Glucose Solution on Gastrointestinal Function after Major Abdominopelvic Surgery

Background

Gastrointestinal (GI) complications often delay recovery after radical cystectomy with urinary diversion. The authors investigated if perioperative administration of a potassium-enriched, chloride-depleted 5% glucose solution (G5K) accelerates recovery of GI function.

Methods

This randomized, parallel-group, single-center double-blind trial included 44 consecutive patients undergoing radical cystectomy and pelvic lymph node dissection with urinary diversion. Patients were randomized to receive either a G5K (G5K group) solution or a Ringer’s maleate solution (control group). Fluid management aimed for a zero fluid balance. Primary endpoint was time to first defecation. Secondary endpoints were time to normal GI function, need for electrolyte substitution, and renal dysfunction.

Results

Time to first defecation was not significantly different between groups (G5K group, 93 h [19 to 168 h] and control group, 120 h [43 to 241 h]); estimator of the group difference, −16 (95% CI, −38 to 6); P = 0.173. Return of normal GI function occurred faster in the G5K group than in the control group (median, 138 h [range, 54 to 262 h] vs. 169 h [108 to 318 h]); estimator of the group difference, −38 (95% CI, −74 to −12); P = 0.004. Potassium and magnesium were less frequently substituted in the G5K group (13.6 vs. 54.5% [P = 0.010] and 18.2 vs. 77.3% [P &lt; 0.001]), respectively. The incidence of renal dysfunction (Risk, Injury, Failure, Loss and End-stage kidney disease stage “risk”) at discharge was 9.1% in the G5K group and 4.5% in the control group; P = 1.000.

Conclusions

Perioperative administration of a G5K did not enhance first defecation, but may accelerate recovery of normal GI function, and reduces potassium and magnesium substitution after radical cystectomy and urinary diversion.

Orthotopic genital sparing radical cystectomy in pre-menopausal women with muscle-invasive bladder carcinoma: A prospective study

INTRODUCTION

Invasive cancer bladder is a life-threatening disease that is best treated with radical cystectomy and a suitable urinary diversion. The aim of this study was to evaluate the oncological outcome, voiding and sexual functions after genital sparing radical cystectomy with orthotopic bladder reconstruction in pre-menopausal women with bladder cancer.

MATERIALS AND METHODS

18 pre-menopausal women who underwent radical cystectomy and orthotopic urinary diversion with preservation of genital organs were included for this study. The patients were followed-up clinically and radiologically to assess their oncological outcome in addition to their voiding and sexual function.

RESULTS

Mean age of the patients was 37.8 years, and the median follow-up after surgery was 70 months. One patient was lost to follow-up at 12 months post-operatively. The surgery was completed as planned in all patients, with a mean operative time of 290 min and an average blood loss of 750 mL. 14 patients were able to void satisfactorily, being continent day and night, while four patients needed clean intermittent catheterization. Sexual life remained unchanged in 15 cases, while three patients reported dysparunea. Till the last follow-up, there was no local recurrence while distant metastases were detected in three cases, two of whom died.

CONCLUSIONS

Genital sparing cystectomy is a valid option for managing carefully selected women with muscle-invasive bladder cancer with good functional and sexual outcomes.

Standard cystectomy fits all: truth or myth?

Radical cystectomy (RC) with pelvic lymph node dissection (PLND) followed by urinary diversion is the treatment of choice for muscle-invasive bladder cancer (BC) and non-invasive BC refractory to transurethral resection of the bladder (TUR-B) and/or intravesical instillation therapies. Since the morbidity and possible mortality of this surgery are relevant, care must be taken in the preoperative selection of patients for the various organ-sparing procedures (e.g., bladder-sparing, nerve sparing, seminal vesicle sparing) and various types of urinary diversion. The patient's performance status and comorbidities, along with individual tumor characteristics, determine possible surgical steps during RC. This individualized approach to RC in each patient can maximize oncological safety and minimize avoidable side effects, rendering 'standard' cystectomy a surgery of the past.

Evaluating sexual function in women after radical cystectomy as treatment for bladder cancer

OBJECTIVE

Sexual function remains a relatively unexplored field within urology, especially for female patients who have undergone radical cystectomy (RC). The aim of this study was to shed light on this area.

MATERIALS AND METHODS

The Female Sexual Function Index (FSFI) questionnaire and other selective questions regarding sexual function were sent to 71 women who had undergone RC and were alive 1 year postsurgery. Forty-one completed questionnaires were returned and analysed using simple descriptive statistical analysis, owing to the small sample size.

RESULTS

The median age of the patients was 67 years (range 39-91 years). Seventy-eight per cent reported being sexually active before surgery and 37% post-surgery. The median FSFI score postsurgery was 4.8 (range 1.2-32). The highest FSFI score was seen in the category of satisfaction, which consists of questions regarding closeness with partner, sexual relationship and overall sex life. Lowest FSFI scores were seen for lubrication, orgasm and pain. Twenty-seven per cent of patients wanted more information on the impact RC would have on their sex lives and many asked for information for their partners.

CONCLUSION

Despite being based on a limited number of patients, this study indicates a need for improvement within this field. Most patients scored below 26 on the FSFI questionnaire, the cut-off for sexual dysfunction. However, many reported being satisfied overall. Thus, the physician's main goal is to identify patients in need of more information and guidance before and after surgery.

Sacrocolpopexy with polypropylene tape as valuable surgical modification during cystectomy with orthotopic ileal bladder: functional results

Introduction. Urinary diversion is very often associated with urinary retention and urinary incontinence. In this study, a surgical modification during cystectomy with orthotopic ileal neobladder is presented. Material and Methods. Female patients enrolled in the study (n-24) were subjected to sacrocolpopexy during the operation. Apart from oncological control, the follow-up consisted of 1-hour inlay test and questionnaires (UDI-6 and IIQ-7) in the 3rd, 6th, and 12th month after the operation. In the 12th month after the surgery, the urodynamic pressure-flow test was performed. Outcomes were compared with the control group (n-18) in which sacrocolpopexy was not implemented. Results. The study group was characterised by reduced urinary retention and improved continence. Conclusion. Sacrocolpopexy during cystectomy with orthotopic ileal bladder is a valuable surgical method which provides patients with a better quality of life.

Summary of the 8th Annual Bladder Cancer Think Tank: Collaborating to move research forward

OBJECTIVES

The 8th Annual Bladder Cancer Think Tank (BCAN-TT) brought together a multidisciplinary group of clinicians, researchers, and patient advocates in an effort to advance bladder cancer research.

METHODS AND MATERIALS

With the theme of "Collaborating to Move Research Forward," the meeting included three panel presentations and seven small working groups.

RESULTS

The panel presentations and interactive discussions focused on three main areas: gender disparities, sexual dysfunction, and targeting novel pathways in bladder cancer. Small working groups also met to identify projects for the upcoming year, including: (1) improving enrollment and quality of clinical trials; (2) collecting data from multiple institutions for future research; (3) evaluating patterns of care for non-muscle-invasive bladder cancer; (4) improving delivery of care for muscle-invasive disease; (5) improving quality of life for survivors; (6) addressing upper tract disease; and (7) examining the impact of health policy changes on research and treatment of bladder cancer.

CONCLUSIONS

The goal of the BCAN-TT is to advance the care of patients with bladder cancer and to promote collaborative research throughout the year. The meeting provided ample opportunities for collaboration among clinicians from multiple disciplines, patients and patient advocates, and industry representatives.

Urinary diversion: long-term functional aspects

Functional aspects and quality of life (QOL) of patients with a urinary diversion (UD) represent important issues in Urology. Any form of UD has its specific problems. In experienced hands and with regular long-term follow-up, serious complications can be avoided and excellent long-term results can be achieved. Thus, the selection of an appropriate UD is critical to patient's long-term satisfaction. Patients must be fully counseled in all types of UD and should have ready access to all options. There are 3 kinds of factors to be considered in the selection of UD: patient, physician, and general factors. In the pre-operative counseling, it is mandatory to explain all factors that over time may contribute to affect the patient's urinary tract function and QOL, mainly linked to long-term complications of UD. One of the most important requirements for any bladder substitution is that it should not jeopardize the renal function. There are many urological and non-urological potential reasons for deterioration in renal function following UD. Continence results after neobladder (NB) are difficult to compare between series published in the literature because of a lack of consensus of definitions, varied follow-up periods, and different mechanisms of data collection. In up to 22% of patients with NB, significant residual urine volumes were observed. The overall patients' QOL reported in most articles was good, irrespective of the type of UD. QOL of patients with a well functioning NB seems to be significantly better than other forms of diversion. Well-designed randomized prospective trials are warranted to render definitive conclusions.

Restrictive Deferred Hydration Combined with Preemptive Norepinephrine Infusion during Radical Cystectomy Reduces Postoperative Complications and Hospitalization Time

Background:

Anesthetics and neuraxial anesthesia commonly result in vasodilation/hypotension. Norepinephrine counteracts this effect and thus allows for decreased intraoperative hydration. The authors investigated whether this approach could result in reduced postoperative complication rate.

Methods:

In this single-center, double-blind, randomized, superiority trial, 166 patients undergoing radical cystectomy and urinary diversion were equally allocated to receive 1 ml·kg−1·h−1 of balanced Ringer’s solution until the end of cystectomy and then 3 ml·kg−1·h−1 until the end of surgery combined with preemptive norepinephrine infusion at an initial rate of 2 µg·kg−1·h−1 (low-volume group; n = 83) or 6 ml·kg−1·h−1 of balanced Ringer’s solution throughout surgery (control group; n = 83). Primary outcome was the in-hospital complication rate. Secondary outcomes were hospitalization time, and 90-day mortality.

Results:

In-hospital complications occurred in 43 of 83 patients (52%) in the low-volume group and in 61 of 83 (73%) in the control group (relative risk, 0.70; 95% CI, 0.55–0.88; P = 0.006). The rates of gastrointestinal and cardiac complications were lower in the low-volume group than in the control group (5 [6%] vs. 31 [37%]; relative risk, 0.16; 95% CI, 0.07–0.39; P &lt; 0.0001 and 17 [20%] vs. 39 [48%], relative risk, 0.43; 95% CI, 0.26–0.60; P = 0.0003, respectively). The median hospitalization time was 15 days [range, 11, 27d] in the low-volume group and 17 days [11, 95d] in the control group (P = 0.02). The 90-day mortality was 0% in the low-volume group and 4.8% in the control group (P = 0.12).

Conclusion:

A restrictive-deferred hydration combined with preemptive norepinephrine infusion during radical cystectomy and urinary diversion significantly reduced the postoperative complication rate and hospitalization time.

Primary and secondary malignant involvement of gynaecological organs at radical cystectomy for bladder cancer: review of literature and retrospective analysis of 360 cases

The pathological analysis of cystectomy specimens from 360 female patients who underwent radical cystectomy for bladder cancer was retrospectively reported. The uterus was not available in 29 specimens, while one ovary was absent in 18 specimens and the two ovaries were absent in 20 specimens. Uterine involvement was observed in one case of transitional cell carcinoma, and benign uterine pathology was detected in 37 cases. All patients had normal ovaries, while the vagina was involved in 13 cases. A total of 12% of the patients had urethral involvement. None of the 29 patients, in whom the internal genitalia were totally or partially preserved, had late ovarian, vaginal or uterine recurrence at the last follow-up. Thus, the preservation of female internal genitalia in young patients undergoing radical cystectomy should be considered under strict criteria (low-grade, low-stage tumours away from the bladder neck). This will improve the quality-of-life (QoL) and the functional outcome without compromising cancer control.
