[Innovative prolapse surgery without mesh implants]. / Innovative Deszensuschirurgie ohne Gewebeersatz.

BACKGROUND: In many countries, such as France, England, USA, Canada, Australia, and New Zealand, alloplastic material in prolapse surgery has been paused due to the US Food and Drug Administration (FDA) warning, and restricted in other countries like the Netherlands and Sweden. For Europe and thus Germany, the SCENIHR report allows alloplastic material to be used for prolapse repair after recurrence and in other special situations. QUESTION: Which established and innovative prolapse surgeries without alloplastic material are currently available? METHODS: A literature search was carried out on established, guideline-compliant pelvic floor surgeries without alloplastic material as well as innovative new approaches. RESULTS: An established procedure for a defect in the anterior compartment is anterior colporrhaphy, which is associated with a high recurrence rate. The double-layered anterior colporrhaphy is a new approach and so far is associated with an improved 19-month outcome. Apical pelvic organ prolapse can be corrected by sacrouterine ligament fixation and vaginal sacrospinous fixation. New innovative techniques include laparoscopic unilateral pectineal suspension and the use of the semitendinosus tendon autograft to perform pectopexy or sacropexy. However, long-term data are still pending. In case of a posterior vaginal wall prolapse, posterior colporrhaphy is the therapy of choice and is associated with good success rates. CONCLUSION: Well-known surgical procedures with native tissue are experiencing a renaissance and new, innovative surgical approaches with good postoperative results are being developed. However, long-term studies are still necessary.

Double-layered anterior colporrhaphy (DAC)-video and mid-term follow-up of 60 patients.

INTRODUCTION AND HYPOTHESIS: Anterior colporrhaphy (AC) exhibits high recurrence rates, and this issue is not appropriately addressed by alloplastic material, which often necessitates reoperation. Aiming to improve the anatomical cure rate, we implemented double-layered anterior colporrhaphy (DAC). With a retrospective investigation, precise description and video of the surgical technique, we want to contribute to the development of native tissue anterior repair. METHODS: Women treated by DAC and vaginal hysterectomy were included. Primary outcome was anatomic cure defined as prolapse < stage 2. Secondary outcomes were complication rate, resolution of postvoid residual urine, reoperation for prolapse and patient satisfaction. Follow-up encompassed a clinical gynecologic examination, the German Pelvic Floor Questionnaire and a response scale for postoperative quality of life (QoL). The key difference between DAC and AC is the continuous suture followed by the traditional interrupted sutures. RESULTS: One hundred one patients were eligible, and 60 patients attended follow-up. Cure was achieved in 49 cases (81.7%) of cystocele with a median follow-up of 19.3 months. Fifty-five patients (91.7%) indicated an improvement in QoL. CONCLUSIONS: We observed high anatomic cure rate and satisfaction after DAC. With description and video of the technique, it is reproducible and comparable to other methods. Randomized controlled trials should follow.

Clinical relevance of neurological evaluation in patients suffering urinary retention in the absence of subvesical obstruction.

PURPOSE: Clinical relevance of neurological evaluation in patients suffered urinary retention in the absence of subvesical obstruction. Determining whether (1) women complaining residual bladder volume without prolapse and obstruction always suffer pudendal nerve damage; (2) neurogenic damage can be linked to patients history/clinical examination; (3) therapy alters regarding to neurological findings; and (4) electromyography (EMG) of musculus sphincter ani externus (MSAE) can be omitted with electronically stimulated pudendal nerve latency (ESPL) as the standard investigation. METHODS: Women with urinary retention without ≥stage 2 prolapse or obstruction have neurological investigation including vaginally and anally pudendal terminal nerve latency (PTNL) (>2.4 ms considered abnormal) and EMG seen 7/2005-04/2010. RESULTS: (1) 148/180 (82.2%) suffered at least moderate neurogenic damage and (2) severe neurogenic damage occurs with urge odds ratio (OR) = 3.1 or age (OR = 3.2). Correlations: spasticity with therapy changes (OR = 11.1), latencies. (a) Anally: (i) right and peripheral neuropathy (PNP) (OR = 2.5), chemotherapy (OR = 5.0); (ii) left and PNP (OR = 3.9), chemotherapy (OR = 4.8); (iii) left or right with PNP (OR = 3.9), chemotherapy (OR = 6.8); and (iv) left and right with chemotherapy (OR = 5.0). (b) Vaginally: (i) right with age >60 (OR = 3.2), radical operation (OR = 10.6); (ii) left with diabetes mellitus (OR = 2.5); and (iii) left or right with age (OR = 3.3), radical operation (OR = 8.7). (3) 19.6% therapy changes (36 patients). (4) Neither EMG nor ESPL can be replaced one by another (p = 0.12 anal, p = 0.05 vaginal). CONCLUSION: Red flags are neurogenic damage, age >60, chemotherapy, PNP, radical operation or diabetes. In unclear situations, EMG and ESPL need to be performed to gain relevant information.

Diagnosis and Therapy of Female Pelvic Organ Prolapse. Guideline of the DGGG, SGGG and OEGGG (S2e-Level, AWMF Registry Number 015/006, April 2016).

Aims: The aim was to establish an official interdisciplinary guideline, published and coordinated by the German Society of Gynecology and Obstetrics (DGGG). The guideline was developed for use in German-speaking countries. In addition to the Germany Society of Gynecology and Obstetrics, the guideline has also been approved by the Swiss Society of Gynecology and Obstetrics (SGGG) and the Austrian Society of Gynecology and Obstetrics (OEGGG). This is a guideline published and coordinated by the DGGG. The aim is to provide evidence-based recommendations obtained by evaluating the relevant literature for the diagnostic, conservative and surgical treatment of women with female pelvic organ prolapse with or without stress incontinence. Methods: We conducted a systematic review together with a synthesis of data and meta-analyses, where feasible. MEDLINE, Embase, Cinahl, Pedro and the Cochrane Register were searched for relevant articles. Reference lists were hand-searched, as were the abstracts of the Annual Meetings of the International Continence Society and the International Urogynecological Association. We included only abstracts of randomized controlled trials that were presented and discussed in podium sessions. We assessed original data on surgical procedures published since 2008 with a minimum follow-up time of at least 12 months. If the studies included descriptions of perioperative complications, this minimum follow-up period did not apply. Recommendations: The guideline encompasses recommendations for the diagnosis and treatment of female pelvic organ prolapse. Recommendations for anterior, posterior and apical pelvic organ prolapse with or without concomitant stress urinary incontinence, uterine preservation options, and the pros and cons of mesh placements during surgery for pelvic organ prolapse are presented. The recommendations are based on an extensive and systematic review and evaluation of the current literature and include the experiences and specific conditions in Germany, Austria and Switzerland.

Vaginal Revision of a Haematoma after Placement of Retropubic Tapes in Two Cases.

Formation of a haematoma after placement of retropubic tapes for stress incontinence is a rare but typical complication potentially requiring a subsequent operation. Under certain circumstances, haematoma removal by a vaginal approach represents a milder alternative to the subperitoneal laparotomy approach under general anaesthesia. We present two cases of vaginal haematoma revision after placement of retropubic tapes. By means of this gentle alternative to the standard laparotomy approach we could avoid general anaesthesia in one case and perform the operation under analgosedative local anaesthesia. In the second case, use of the vaginal approach enabled us to avoid a laparotomy in this obese patient with a superinfected haematoma that could have led to a possible secondary wound healing problem.

Transvaginal single-incision mesh reconstruction for recurrent or advanced anterior vaginal wall prolapse.

AIMS: Single-incision transvaginal mesh for reconstruction of Level I and II prolapses in women with recurrent or advanced prolapse. We evaluated functional, anatomical, sonomorphological and quality-of-life outcome. METHODS: Data were collected retrospectively for preoperative parameters and at follow-up visits. Anatomical cure was assessed with vaginal examination using the ICS-POP-Q system; introital-ultrasound scan for postvoidal residual and description of mesh characteristics was performed. We applied a visual analogue scale (VAS) and the German Pelvic Floor Questionnaire to assess quality-of-life. RESULTS: Seventy women with cystocele (III: 61.3%/IV: 16%), all post-hysterectomy and in majority (81.4%) after previous cystocele repair, were operated using a single-incision transvaginal technique. Overall anatomical success rate was 95.7% with significant improvement in quality-of-life (p < 0.0001). Mesh erosion occurred in 5.7%, one patient presented symptomatic vaginal vault prolapse. Postvoidal residual declined significantly (58 vs. 2.9%). Sonographic mesh length was 55.7% of implanted mesh with a wide range of mesh position, but no signs of mesh dislocation. There was no de novo dyspareunia reported, one case of preoperative existing dyspareunia worsened. No severe adverse event was observed. CONCLUSIONS: We hereby present a trial of a high-risk group of patients requiring reconstruction of anterior and apical vaginal wall in mostly recurrent prolapse situation. Our data support the hypothesis of improved anatomical and functional results and less mesh shrinkage caused by the single-incision technique with fixation in sacrospinous ligament in combination with modification in mesh quality compared to former multi-incision techniques.

Rupture of the Left Renal Fornix after Vaginal Repair of Postpartum Vesicovaginal Fistula.

Surgical repair of vesicovaginal fistulas carries a risk of postoperative obstruction of the upper urinary tract. In the case described here, a postoperative intramural edema led to urinary retention and subsequent rupture of the renal pelvis. This is a rare but typical urological emergency. If patients complain postoperatively of flank pain, ultrasound should be carried out promptly. If the findings are unclear (no urinary retention despite clinical symptoms), additional computed tomography should be performed to determine whether rupture of the fornix has occurred.

Impact of Retropubic vs. Transobturator Slings for Urinary Incontinence on Myofascial Structures of the Pelvic Floor, Adductor and Abdominal Muscles.

Suburethral tension-free slings (tapes or bands) are an essential component in the operative treatment of urinary incontinence. In the present contribution the influence of the type of suburethral sling (retropubic vs. transobturator) on the myofascial structures of the abdominal, adductor and pelvic floor muscles is examined. For this purpose, 70 patients were prospectively observed clinically and physiotherapeutically. Significant differences were seen in the improvement of the pelvic floor musculature (strength, endurance, speed) after placement of a suburethral sling, irrespective of whether it was of the retropubic or the transobturator type. Thus, after surgical treatment patients should be encouraged to undertake further pelvic floor exercising or this should be prescribed for them. There were no significant changes in the abdominal and adductor muscles but there were slight increases with regard to pain level, pain on palpation, and trigger points after placement of both types of sling; thus this is not a criterion in the decision as to which type of sling to use.

Ca(2+) signals, NAADP and two-pore channels: role in cellular differentiation.

Ca(2+) signals regulate a wide range of physiological processes. Intracellular Ca(2+) stores can be mobilized in response to extracellular stimuli via a range of signal transduction mechanisms, often involving recruitment of diffusible second messenger molecules. The Ca(2+) -mobilizing messengers InsP3 and cADPR release Ca(2+) from the endoplasmic reticulum via the InsP3 and ryanodine receptors, respectively, while a third messenger, NAADP, releases Ca(2+) from acidic endosomes and lysosomes. Bidirectional communication between the endoplasmic reticulum (ER) and acidic organelles may have functional relevance for endolysosomal function as well as for the generation of Ca(2+) signals. The two-pore channels (TPCs) are currently strong candidates for being key components of NAADP-regulated Ca(2+) channels. Ca(2+) signals have been shown to play important roles in differentiation; however, much remains to be established about the exact signalling mechanisms involved. The investigation of the role of NAADP and TPCs in differentiation is still at an early stage, but recent studies have suggested that they are important mediators of differentiation of neurones, skeletal muscle cells and osteoclasts. NAADP signals and TPCs have also been implicated in autophagy, an important process in differentiation. Further studies will be required to identify the precise mechanism of TPC action and their link with NAADP signalling, as well as relating this to their roles in differentiation and other key processes in the cell and organism.

Vaginal Vault Suspension at Hysterectomy for Prolapse - Myths and Facts, Anatomical Requirements, Fixation Techniques, Documentation and Cost Accounting.

Vaginal vault suspension during hysterectomy for prolapse is both a therapy for apical insufficiency and helps prevent recurrence. Numerous techniques exist, with different anatomical results and differing complications. The description of the different approaches together with a description of the vaginal vault suspension technique used at the Department for Urogynaecology at St. Hedwig Hospital could serve as a basis for reassessment and for recommendations by scientific associations regarding general standards.

Normal Pressure Hydrocephalus as Cause of Urinary Incontinence - A Shunt for Incontinence.

Normal pressure hydrocephalus is a frequently missed clinical entity with the typical symptom triad of gait disturbance, urinary incontinence and dementia (Hakim's triad) and occurs mostly from the 6th decade of life onwards. Early therapy can lead to a complete reversal of the symptoms. The present case report is intended to draw attention to the clinical entity normal pressure hydrocephalus (NPH) since the afflicted patients often primarily consult a gynaecologist on account of the urinary bladder disorders.

Obstetric levator ani muscle injuries: current status.

Levator ani muscle (LAM) injuries occur in 13-36% of women who have a vaginal delivery. Although these injuries were first described using magnetic resonance imaging, three-dimensional transperineal and endovaginal ultrasound has emerged as a more readily available and economic alternative to identify LAM morphology. Injury to the LAM is attributed to vaginal delivery resulting in reduced pelvic floor muscle strength, enlargement of the vaginal hiatus and pelvic organ prolapse. There is inconclusive evidence to support an association between LAM injuries and stress urinary incontinence and there seems to be a trend towards the development of fecal incontinence. Longitudinal studies with long-term follow-up assessing the LAM before and after childbirth are lacking. Furthermore, the consequence of LAM injuries on quality of life due to prolapse and/or urinary and fecal incontinence have not been evaluated using validated questionnaires. Direct comparative studies using the above-mentioned imaging modalities are needed to determine the true gold standard for the diagnosis of LAM injuries. This would enable consistency in definition and classification of LAM injuries. Only then could high-risk groups be identified and preventive strategies implemented in obstetric practice.

Electromotive drug administration for treatment of therapy-refractory overactive bladder.

PURPOSE: Evaluate the benefits of electromotive drug administration (EMDA) as an alternative technique in patients with chronic overactive bladder in terms of improvement of symptoms, quality of life, and sexuality. MATERIAL AND METHODS: A total of 72 patients with therapy-refractory overactive bladder according to the ICS (International Continence Society) definition, were treated by EMDA. The regimen consisted of three treatment cycles, each with 3 instillations at 2-week intervals. The solution instilled consisted of 100 mL 4% lidocaine, 100 mL distilled water, 40 mg dexamethasone, and 2 mL epinephrine. Peri-interventionally, a urine test and close circulatory monitoring were performed. All women underwent urodynamic testing and cystoscopy and kept a voiding diary. A comprehensive history was obtained, a quality of life questionnaire administered, and a gynecologic examination performed before initiation of therapy. The women underwent follow-up at 12 months after the end of therapy. RESULTS: The patients had a mean age of 63 (+/- 11.2) years. Bladder capacity improved significantly by 109 mL (+/- 55 mL) in 51 (71%) patients (p = 0.021). The number of micturitions/day decreased significantly to 7 (+/- 2) (p = 0.013). Quality of life was improved in 54 patients (75%); p = 0.024) and sexuality in 39 (54%); p = 0.020). CONCLUSIONS: The results suggest that EMDA can improve both quality of life and sexuality in patients with therapy-refractory chronic overactive bladder.

[External anal sphincter repair using the overlapping technique in patients with anal incontinence and concomitant pudendal nerve damage]. / Analsphinkter-repair mit einer überlappenden nahttechnik bei patientinnen mit analinkontinenz und nervus-pudendus-schaden.

BACKGROUND: No single surgical technique has so far emerged as the optimal approach to treat defects of the anal sphincter in patients with postpartum fecal incontinence. Our approach is to repair the external sphincter using the overlapping technique to optimize morphological and clinical outcome. The results were correlated with preoperatively determined pudendal nerve function. METHODS: Thirty-five patients were followed up for three years after repair of the external anal sphincter. The patients had grade 2 (n = 29) or grade 3 (n = 6) fecal incontinence. Nineteen (54 %) patients had a concomitant defect of the internal anal sphincter and 28 (80 %) had abnormal pelvic floor EMG findings. Before surgery, all patients underwent conservative treatment with biofeedback and electrostimulation. The muscle ends were overlapped with Vicryl 4-0 sutures. A standardized protocol was used for the perioperative management in all patients. RESULTS: Of the 35 patients who underwent overlapping repair of the external anal sphincter, 32 (91 %) had a satisfactory result at 3-year follow-up based on sonomorphological criteria. These 32 patients were continent for solid and liquid stools. Six of the 35 patients (17 %) continued to have flatus incontinence. Two (6 %) patients were improved and one patient (3 %) had unchanged incontinence. Pudendal nerve damage had no effect on the outcome of surgery. CONCLUSIONS: Our findings at 3-year follow-up show good results for the overlapping repair of the external anal sphincter in terms of morphology and clinical symptoms. This outcome depends on an adequate preoperative pelvic floor conditioning, optimal perioperative management, and use of a standardized operative technique. Surgical repair of the morphological defect is recommended even in patients with pudendal nerve damage.

Sonomorphological evaluation of polypropylene mesh implants after vaginal mesh repair in women with cystocele or rectocele.

OBJECTIVE: To investigate whether the sonographically measured size of the mesh implant in women who had undergone vaginal polypropylene mesh repair 6 weeks previously correlates with the original size of the mesh and whether the mesh ensures complete support of the anterior or posterior compartment. METHODS: Forty postmenopausal women with anterior or posterior vaginal wall prolapse and sonographically proven cystocele (n = 20) or rectocele (n = 20) were evaluated preoperatively and 6 weeks after vaginal mesh repair. Introital ultrasound was performed to identify the polypropylene mesh and measure its distal to proximal length and configuration as well as its thickness. The initial mesh length was compared with that measured by ultrasound 6 weeks postoperatively. Vaginal length was measured pre- and postoperatively. RESULTS: The mean +/- SD age of the women was 68 +/- 7 years. The 20 women with cystocele underwent repair by means of anterior transobturator mesh implantation; the initial mesh length was 6.8 +/- 1.1 cm versus 2.9 +/- 0.6 cm postoperatively. The 20 women with rectocele underwent repair by posterior transischioanal mesh implantation; the initial mesh length was 9.9 +/- 0.8 cm versus 3.3 +/- 0.5 cm postoperatively. The mesh supported 43.4% of the length of the anterior vaginal wall and this value was 53.7% for the posterior wall (P = 0.016). CONCLUSION: Sonography is recommended for postoperative evaluation of the anterior and posterior mesh positions after prolapse surgery. There is a considerable discrepancy between the implanted mesh size and the length measured 6 weeks later by postoperative ultrasound. Published by John Wiley & Sons, Ltd.

Follow-up after polypropylene mesh repair of anterior and posterior compartments in patients with recurrent prolapse.

To retrospectively analyze the outcome of surgery in women followed up for 1 year after vaginal repair with the Apogee (support of posterior vaginal wall) or Perigee (support of anterior vaginal wall) system. A total of 120 patients with recurrent cystocele and/or rectocele or with combined vaginal vault prolapse were treated by either posterior or anterior mesh interposition depending on the defect. Follow-up after 1 year (+/-31 days) comprised a vaginal examination with prolapse grading using the POP-Q system, measurement of vaginal length, evaluation of the vaginal mucosa, and exploration for mesh erosions. Postoperatively, 112 (93%) women were free of vaginal prolapse, whereas 8 (7%) had level 2 defects. Erosions occurred significantly more often (p = 0.042) in patients treated with the Perigee system. Our results suggest that the Apogee and Perigee repair systems (monofilament polypropylene mesh) yield excellent short-term results after 1 year.
