Introduction

Pelvic organ prolapse (POP) is a growing clinical problem in gynecology. The most common risk factors for this disorder include multiparity, history of vaginal delivery, older age and obesity [1, 2]. The incidence of POP increases with age, with especially high rates after the menopause, due to tissue atrophy induced by hypoestrogenism [1]. In 1996, the International Continence Society (ICS) published a unified classification of POP (Pelvic Organ Prolapse – Quantification; POP-Q) which enables the clinician to precisely and objectively assess the degree of the prolapse, solely on the basis of clinical examination [3]. Available data show that approximately 46% of women aged 15-96 years have experienced some degree of POP [4].
Female genital prolapse is not only an anatomical disorder. It is also associated with functional problems regarding miction, defecation and sexual activity. It may also cause chronic pelvic pain [5, 6]. Consequently, POP may cause significant deterioration of the quality of life resulting in gradual professional, social and familial isolation. Therefore, the goal of surgical treatment of this condition is not only to restore adequate anatomy, but also to improve functionality.
Among various surgical techniques and their modifications, the abdominal sacropexy, described in 1962 by F. Lane is characterized by good and durable results [7]. Numerous authors emphasize the long-lasting effect of this surgery with regard to the restoration of normal anatomy. This issue becomes particularly important while considering the results of a cohort study which showed high reoperation rates (reaching 30%) after surgical treatment of incontinence and genital prolapse [8].
In the literature, the reports concerning the subjective assessment of quality of life of women who underwent abdominal cervicosacropexy are scarce.
The aim of this study was to perform a complex analysis of treatment effects, particularly the subjective assessment of quality of life in women who underwent cervicosacropexy via laparotomy for POP correction.

Material and methods

The study group comprised 40 patients who were operated for POP in the 1st Department of Obstetrics and Gynecology, Medical University of Warsaw, from April 2012 to June 2013. The degree of the prolapse was evaluated using an international unified classification of POP. The study group consisted of women diagnosed with POPQ stage IV and POPQ stage IIIc. They were all scheduled for abdominal cervicosacropexy (supracervical hysterectomy without ovaries and cervicosacropexy with polypropylene mesh). Before the surgery, all patients were interviewed. Information concerning their obstetric history, hormonal status and any previous procedures performed for the prolapse was obtained. All women filled in a questionnaire regarding the subjective evaluation of quality of life before and 6 months after the surgery. It comprised questions about the general quality of life with POP and the quality of sexual life, both rated using a 10-point analogue scale. Moreover, information on the frequency of accompanying conditions, such as stress urinary incontinence (SUI), overactive bladder (OAB), urinary retention (post void residual volume > 100 ml, measured using transabdominal ultrasound), defecation disorders and pelvic pain was obtained. Stress urinary incontinence was diagnosed in all cases on the basis of caught test and 1 hour pad test. Overactive bladder was diagnosed on the basis of urinary diary and urodynamic tests. The effect of the operation was evaluated using the POPQ system. When the patient was diagnosed with POPQ stage II or greater, the treatment was considered a failure.

Surgical technique

Laparotomy via suprapubic transverse incision was performed. In the event of an intact uterus, the supracervical hysterectomy was performed. Subsequently, the parietal peritoneum at the level of promontory was incised and the anterior longitudinal ligament was exposed. The incision was extended to the level of the cul-de-sac. A polypropylene mesh was then fixed to the cervical stump and the promontory with non-absorbable sutures. The mesh was covered with peritoneum and thus located extraperitoneally. Perioperative antibiotic prophylaxis was administered in all cases. The effect of procedure was assessed during the control visits in the Urogynecological Outpatient Clinic at 4 weeks, 6 months and 18 months after the surgery. T-test for mean in paired samples and Wilcoxon sign rank test for paired observations were used for statistical analysis.

Results

The characteristics of the study group are shown in Table I. An accurate correction of the prolapse was achieved in all patients and no recurrence was observed in any of the patients during 18 months of follow-up. Among the disorders accompanying the prolapse, statistically significant differences were observed with regard to symptoms of OAB (urgency, pollakiuria and nocturia): 50% prior vs. 17.65% after operation, p = 0.016, as well as urinary retention: 32.36% before the procedure and 2.5% post-surgery, p = 0.0067. In 42% of patients, SUI occurred pre surgery. After the surgery, SUI was diagnosed in 38.24% of women. The difference was not statistically significant. De novo SUI occurred in 3 (7.3%) patients. Constipation was reported by 25% of patients before operation and 27% post-surgery. Two patients were re-operated due to mechanical ileus: one after 5 months, the other – 10 days post-surgery. In both cases, intraperitoneal adhesions were the cause of the ileus. One patient was re-operated because of hematoma of the rectus abdominis muscle diagnosed in the early post-surgery period. The mean overall subjective assessment of the quality of life in relation to pelvic organ prolapse was 2.77 (SD 2.39, 95% CI: 1.87-8.64), post operation: 9.03 (SD 1.08, 95% CI: 8.66-9.43). The difference was highly statistically significant – p < 0.001 (Fig. 1). Fifty-three percent of women were sexually active pre surgery, whereas after the operation – 47%. The average subjective evaluation of the quality of sexual life before surgery was 5.75 (SD 2.52, 95% CI: 4.41-7.1), post-surgery: 7.93 (SD 1.77, 95% CI: 6.9-8.95), p = 0.0017 (Fig. 2).

Discussion

Pelvic organ prolapse and the accompanying functional disorders are a growing clinical problem of current gynecology. Among various surgical techniques, abdominal cervicosacropexy and colposacropexy are considered one of the most effective techniques, with the effect persisting in 95% of women for 3 years post-surgery and in 80-90% for longer than 5 years [9-12]. Several-year observations proved long-term effects of the procedure in 74% of patients.
A randomized prospective study comparing the results of sacrocolpopexy with the effects of fixation of the vagina to the sacro-spinal ligament (SSLF) showed that the former operation was more effective. After 5 years, the optimal correction was achieved in 58% of the women, compared to only 29% of women who underwent SSLF. Reoperation was necessary in 33% of women [8].
In an analysis published in 2004, the effectiveness of SSLF was proved to be similar to that of cervicosacropexy (76% vs. 69%). However, the cumulative rate of recurrence of prolapse of the anterior vaginal wall and vaginal fornix was higher in the SSLF group (45% vs. 13%). Moreover, SUI occurred more often in these patients (33% vs. 9%) [13]. In the current study no POP recurrence was reported.
Stress urinary incontinence occurred with an equal frequency before and after the surgery. Three patients suffered from de novo SUI post-surgery. Lack of reduction in the incidence of SUI as well as the occurrence of de novo SUI was confirmed by other researchers. Reddy et al. observed de novo SUI in 50% of the operated women [14]. Both Hilger et al. and Joen et al., who analyzed the effects of abdominal sacrocolpopexy, diagnosed this disorder in more than half of the operated patients [15, 16]. In a study performed by Lefranc et al., 67% of the 85 analyzed patients suffered from SUI pre surgery. In those women, Burch colposuspension or a sling procedure (Goebbel-Stockel) was performed simultaneously with sacrofixation. Still, the recurrence was observed in 40% of women [12]. Podratz et al. reported persistence of SUI in 5 out of 6 women in whom sacrofixation was performed simultaneously with retropubic urethropexy [11]. Stress urinary incontinence usually appears during the first three months post operation, when the patient resumes her normal activity. Various factors contribute to this complication, including loss of the support that is normally provided by the uterus and vagina to the urethra, increased urethrovesical angle and surgical hypercorrection of the anterior vaginal wall, particularly in women with low-pressure urethra. The above mentioned studies also show low effectiveness of concurrent prolapse correction and anti-incontinence surgery. The opposing forces that result from abdominal sacropexy and Burch colposuspension are responsible for non-optimal results of colposuspension [11].
At our unit, we perform a cough stress test with full bladder, with the cervix and/or anterior vaginal wall replaced with a speculum, in all patients scheduled for prolapse correction. Thus, most cases of occult SUI are diagnosed and the affected patients are aware of the high probability of incontinence occurring as a complication of prolapse correction.
All women who suffered from persistent or de novo SUI post-surgery were offered an anti-continence operation or non-surgical treatment for the disorder (depending on the indications). The procedure was performed at least 3 months post prolapse correction. It should be underlined that stress urinary incontinence occurrence after POP repair should be always taken into consideration as it may be a serious clinical problem. In the present study, the authors did not notice the difference of the SUI incidence after the surgery, but it is very much probable that it is connected with a small sample size.
Surgical correction of prolapse was associated with a significant reduction in the rates of urinary retention and symptoms of overactive bladder. This was probably the result of accurate restoration of anatomy. No changes in the functioning of the lower digestive tract were observed. This may be caused by the fact that rectocele is the only one of many factors influencing the pathology of intestines. The occurrence of constipation after cervicosacropexy was more prevalent in women who had suffered from this disorder already before the surgery. This proves the multifactorial etiology of this problem.
Few studies raise the issue of sexual activity of women before and after the prolapse correction. The data concerning sexual life of women who underwent abdominal cervicosacropexy that can be found in the literature are retrospective and often unclear due to a variety of confounding factors, such as age, coexisting diseases and medications, as well as hormonal therapy. In the current study, the rate of women who were sexually active pre and post-surgery did not vary significantly. However, among those women who were sexually active, the quality of their sexual life improved. In a research study conducted by Jeon et al., 65% of women were not sexually active before the surgery and the rate did not change after the prolapse correction, but this resulted mainly from lack of a sexual partner, partner’s disease preventing intercourse or lack of sexual drive [16]. Virtanen et al. analyzed the results of a questionnaire filled by 16 sexually active women 3 years post sacrocolpopexy. Forty-three percent of those patients suffered from dyspareunia and 69% had lowered libido [17]. Baessler and Pilsgard obtained results contrary to the above mentioned studies but in accordance with our findings. Nearly 90% of women with dyspareunia reported resolution of the symptom after prolapse correction [18, 19].
In the literature concerning results of surgical correction of POP, little attention is given to the general assessment of quality of life of patients who undergo these surgeries. In fact, the improvement of the quality of life is the primary goal of prolapse correction. Explaining to the patient the possibility of the occurrence of urinary incontinence after surgical correction of POP and presenting a plan to correct it warrants that the woman will not be disappointed with the effects of the surgery. The reported great improvement in the general assessment of the quality of life after surgical treatment of POP shows the importance of this clinical problem and the role of adequate correction in achieving self-acceptance. Among the variety of methods used for POP correction – from pessary treatment, LeFort colpocleisis offered to selected elderly, not sexually active patients, sacrospinal colpopexy, to laparoscopic techniques, abdominal sacrofixation seems to be effective, eliminating also the functional disorders and, what is particularly significant, ensuring an anatomical effect lasting for many years.
Till now the procedure has been performed in more than one hundred women, therefore the final results of self-evaluation of the patients is still being completed.

Conclusions

Cervicosacropexy via laparotomy is an effective method to treat pelvic organ prolapse. It is well accepted by patients and, apart from an objective correction of the prolapse, it is also associated with a significant improvement of the quality of life.
