The impact of a modified ileal neobladder on the lifestyle and voiding patterns in Asian patients

Impact of complications and bladder cancer stage on quality of life in patients with different types of urinary diversions

GOAL

Determine correlation between complications and stage of the disease and their impact on quality of life in patients with different types of ileal urinary derivation after radical cystectomy, and upon estimation of acquired results, to suggest the most acceptable type of urinary diversion.

PATIENTS AND METHODS

In five year period a prospective clinical study was performed on 106 patients, to whom a radical cystectomy was performed due to bladder cancer. Patients were divided into two groups, 66 patients with ileal conduit derivation and 40 patients with orthotopic derivation, whereby in each group a comparison between reflux and anti-reflux technique of orthotopic bladder was made. All patients from both groups filled the Sickness Impact Profile score six months after the operation. All patients had CT urography or Intravenous urography performed, as well as standard laboratory, vitamin B12 blood values, in order to evaluate early (ileus or subileus, wound dehiscence, bladder fistula, rupture of orthotopic bladder, urine extravazation) and late complications (VUR, urethral stricture, ureter stenosis, metabolic acidosis, mineral dis-balance, hypovitaminosis of vitamin B12, increased resorption of bone calcium, urinary infection, kidney damage, relapse of primary disease), so as disease stage and it's impact on quality of life.

RESULTS

From gained results we observe that each category of SIP score correlates with different rate of correlation with the type of operation, group, T, N, and R grade, except work category. Average value of SIP score rises depending on the type of operation and T stage. It is notable that there is no difference in T1 stage, no matter the type of operation. So the average value of SIP score in T1 stage for conduit was 20.3, for Abol-Enein and Ghoneim 17.25 and Hautmann 18.75 respectively. Average value of SIP score in T2 stage for conduit was 31, for Abol-Enein and Ghoneim 19.1 and Hautmann 17.8. Average value of SIP score in T3 stage for conduit was 38.03, for Abol-Enein and Ghoneim 18.75 and Hautmann 19.5. SIP score for T4 was present only in patients with conduit performed and average value od SIP score was 40.42. There is a high level of correlation of late complications and psychosocial and physical dimension with their parameters, while for an independent dimension of correlation is not significant. Early complications have insignificant correlation in all categories of SIP score.

CONCLUSION

Upon analyzing quality of life and morbidity, significant advantage is given to orthotopic derivations, especially Hautmann derivation with Chimney modification, unless there are no absolute contraindications for performing this type of operation. Factors which mostly influence quality of life are cancer stage, type of derivation, late complications and patient age. SIP score, as a well validated questionnaire, are applicable in this kind of research.

Sickness Impact Profile (SIP) Score, a Good Alternative Instrument for Measuring Quality of Life in Patients with Ileal Urinary Diversions

Objective:

To determine the effectiveness of the use of the SIP score and the quality of life impairment in patients with ileal conduit and orthotropic ileal derivations by Hautmann and AbolEnein/Ghoneim.

Methods:

Prospectively evaluated 146 patients in different age groups. In 66 patients ileal conduit derivation was performed, in 20 patients orthotropic derivation using Hautman technique was recorded and in 20 of them AbolEnein/Ghoneim was used. Prior to examining patients with urinary diversions, 40 patients with minor urological symptoms not requiring any active treatment, were surveyed in order to validate SIP score. Six months after the operation, all patients with urinary diversions filled the SIP score questionnaire.

Results:

Using Crombach’s Alpha equation the high reliability of SIP questionnaire was proven. Average scale value was 0,93. Using descriptive statistics mean values of all categories and dimensions of the SIP questionnaire of examined patients were determined, calculated according to the questionnaire manual being converted to percentage. Total value of SIP score for the ileal conduit group was 34,76% and in orthotropic derivation 18,52% respectively. For Hautmann procedure total SIP score was 18,35% and for AbolEnein/Ghoneim 18,7%. In the control group total SIP score was 9%. The most influential dimensions on the total score of ileal conduit were physical and psycho-social, while independent dimension did not significantly influent total SIP score.

Conclusion:

Taking into consideration the lack of questionnaires on quality of life for urinary derivations, SIP score as a general disease influence to the quality of life questionnaire represents a reliable alternative for objectification and quantification of the quality of life upon urinary derivation. According to this instrument, orthotropic derivations provide significantly better quality of life compared to ileal conduit.

Urethra-sparing cystectomy and orthotopic urinary diversion in women with malignant pelvic tumors

BACKGROUND

To the authors' knowledge, few data exist regarding the functional and oncologic outcome of pelvic tumors in women with urethra-sparing cystectomy and orthotopic urinary diversion to the urethra.

PATIENTS AND METHODS

The combined data of 102 women age 28-79 (mean, 59 yrs) years who underwent a urethra-sparing cystectomy and orthotopic urinary diversion for either primary bladder cancer (96 patients), carcinoma of the uterine cervix (2 patients), carcinoma of the vagina (1 patient), primary fallopian tube carcinoma (1 patient), uterine sarcoma (1 patient), or rectal carcinoma (1 patient) were reviewed. The histology of the 96 primary bladder tumors was 81 transitional cell carcinomas (TCC), 8 adenocarcinomas, 5 squamous cell carcinomas, 1 small cell carcinoma, and 1 unclassified. Follow-up ranged from 1.5-100 months (mean, 26 mos; median, 24 mos). In all patients, the bladder neck and up to 1 cm in length of the adjacent urethra were removed with the bladder. An ileal orthotopic neobladder procedure was performed if staging biopsies of the bladder neck and intraoperative frozen section of the urethral margin revealed no tumor.

RESULTS

There was no perioperative mortality, and an early and late complication rate requiring secondary intervention in 5 (5%) and 12 (12%) patients. With 88 of 102 patients alive and 83 of 102 patients disease free, a disease-specific survival of 74% and a disease-free survival of 63% was estimated at 5 years. No pelvic recurrence was seen in 81 patients with TCC. Three pelvic recurrences occurred, two tumors of the inner genitalia and one adenocarcinoma of the bladder, none of them in the area of the urethra or its supplying autonomic nerves. Daytime continence was 82%; nocturnal continence was 72%. Twelve (12%) patients were unable to empty their bladders completely and needed some form of catheterization.

CONCLUSIONS

The functional and oncologic outcome of female patients with an orthotopic urinary diversion to a remnant urethra was found to be comparable to that found in large studies on males. An orthotopic neobladder proved to be an oncologically safe option for women with pelvic tumors and was found to provide quality of life when there was adherence to previously defined selection criteria.

Surgery for invasive bladder tumors: technique and outcome

The operative management of invasive transitional cell carcinoma has advanced significantly in the past year, particularly with respect to continent urinary diversion. The long term safety and efficacy of this form of urinary reconstruction is being established in terms of both operative and metabolic complications. The availability of continent diversion can decrease the interval to cystectomy and therefore may impact positively on survival. It has also been shown that continent diversion can safely be offered to patients at high risk for local recurrence. The importance of urethral sensory threshold on postoperative continence is being established. These findings and others continue to enhance the survival and quality of life of patients undergoing cystectomy for invasive bladder cancer.

Orthotopic bladder augmentation and substitution

Orthotopic bladder augmentation or substitution using intestinal segments has become a standard procedure for many disorders that cause a loss of functional or anatomical bladder capacity. From the technical point of view, reservoir configuration by detubularizing the intestinal segments is the general practice. Various techniques exist, depending which types of segments and which techniques of ureteral implantation are used. Common problems include urinary incontinence, retention, metabolic disorders, and the possibility of secondary malignancies. As a result, research has been conducted into utilizing tissues other than intestine for bladder augmentation or substitution.

Bladder substitution

Preliminary data have shown that composite reservoirs consisting of gastric segments in combination with ileum or colon may reduce metabolic problems. Orthotopic neobladders are the most natural way to reconstruct the urinary bladder and are a safe option in selected male and female patients. Experimental and preliminary clinical data about new methods using autologous muscle transfer and tissue engineering are promising.
