Diagnosis and management of complications following pelvic organ prolapse surgery using a synthetic mesh: French national guidelines for clinical practice.

Complications associated with pelvic organ prolapse (POP) surgery using a synthetic non-absorbable mesh are uncommon (<5%) but may be severe and may hugely diminish the quality of life of some women. In drawing up these multidisciplinary clinical practice recommendations, the French National Authority for Health (Haute Autorité de santé, HAS) conducted an exhaustive review of the literature concerning the diagnosis, prevention, and management of complications associated with POP surgery using a synthetic mesh. Each recommendation for practice was allocated a grade (A,B or C; or expert opinion (EO)), which depends on the level of evidence (clinical practice guidelines). PREOPERATIVE PATIENTS' INFORMATION: Each patient must be informed concerning the risks associated with POP surgery (EO). HEMORRHAGE, HEMATOMA: Vaginal infiltration using a vasoconstrictive solution is not recommended during POP surgery by the vaginal route (grade C). The placement of vaginal packing is not recommended following POP surgery by the vaginal route (grade C). During laparoscopic sacral colpopexy, when the promontory seems highly dangerous or when severe adhesions prevent access to the anterior vertebral ligament, alternative surgical techniques should be discussed per operatively, including colpopexy by lateral mesh laparoscopic suspension, uterosacral ligament suspension, open abdominal mesh surgery, or surgery by the vaginal route (EO). BLADDER INJURY: When a bladder injury is diagnosed, bladder repair by suturing is recommended, using a slow resorption suture thread, plus monitoring of the permeability of the ureters (before and after bladder repair) when the injury is located at the level of the trigone (EO). When a bladder injury is diagnosed, after bladder repair, a prosthetic mesh (polypropylene or polyester material) can be placed between the repaired bladder and the vagina, if the quality of the suturing is good. The recommended duration of bladder catheterization following bladder repair in this context of POP mesh surgery is from 5 to 10 days (EO). URETER INJURY: After ureteral repair, it is possible to continue sacral colpopexy and place the mesh if it is located away from the ureteral repair (EO). RECTAL INJURY: Regardless of the approach, when a rectal injury occurs, a posterior mesh should not be placed between the rectum and the vagina wall (EO). Concerning the anterior mesh, it is recommended to use a macroporous monofilament polypropylene mesh (EO). A polyester mesh is not recommended in this situation (EO). VAGINAL WALL INJURY: After vaginal wall repair, an anterior or a posterior microporous polypropylene mesh can be placed, if the quality of the repair is found to be satisfactory (EO). A polyester mesh should not be used after vaginal wall repair (EO). MESH INFECTION (ABSCESS, CELLULITIS, SPONDYLODISCITIS): Regardless of the surgical approach, intravenous antibiotic prophylaxis is recommended (aminopenicillin + beta-lactamase inhibitor: 30 min before skin incision +/- repeated after 2 h if surgery lasts longer) (EO). When spondylodiscitis is diagnosed following sacral colpopexy, treatment should be discussed by a multidisciplinary group, including especially spine specialists (rheumatologists, orthopedists, neurosurgeons) and infectious disease specialists (EO). When a pelvic abscess occurs following synthetic mesh sacral colpopexy, it is recommended to carry out complete mesh removal as soon as possible, combined with collection of intraoperative bacteriological samples, drainage of the collection and targeted antibiotic therapy (EO). Non-surgical conservative management with antibiotic therapy may be an option (EO) in certain conditions (absence of signs of sepsis, macroporous monofilament polypropylene type 1 mesh, prior microbiological documentation and multidisciplinary consultation for the choice of type and duration of antibiotic therapy), associated with close monitoring of the patient. BOWEL OCCLUSION RELATED TO NON-CLOSURE OF THE PERITONEUM: Peritoneal closure is recommended after placement of a synthetic mesh by the abdominal approach (EO). URINARY RETENTION: Preoperative urodynamics is recommended in women presenting with urinary symptoms (bladder outlet obstruction symptoms, overactive bladder syndrome or incontinence) (EO). It is recommended to remove the bladder catheter at the end of the procedure or within 48 h after POP surgery (grade B). Bladder emptying and post-void residual should be checked following POP surgery, before discharge (EO). When postoperative urine retention occurs after POP surgery, it is recommended to carry out indwelling catheterization and to prefer intermittent self-catheterization (EO). POSTOPERATIVE PAIN: Before POP surgery, the patient should be asked about risk factors for prolonged and chronic postoperative pain (pain sensitization, allodynia, chronic pelvic or non-pelvic pain) (EO). Concerning the prevention of postoperative pain, it is recommended to carry out a pre-, per- and postoperative multimodal pain treatment (grade B). The use of ketamine intraoperatively is recommended for the prevention of chronic postoperative pelvic pain, especially for patients with risk factors (preoperative painful sensitization, allodynia, chronic pelvic or non-pelvic pain) (EO). Postoperative prescription of opioids should be limited in quantity and duration (grade C). When acute neuropathic pain (sciatalgia or pudendal neuralgia) resistant to level I and II analgesics occurs following sacrospinous fixation, a reintervention is recommended for suspension suture removal (EO). When chronic postoperative pain occurs after POP surgery, it is recommended to systematically seek arguments in favor of neuropathic pain with the DN4 questionnaire (EO). When chronic postoperative pelvic pain occurs after POP surgery, central sensitization should be identified since it requires a consultation in a chronic pain department (EO). Concerning myofascial pain syndrome (clinical pain condition associated with increased muscle tension caused by myofascial trigger points), when chronic postoperative pain occurs after POP surgery, it is recommended to examine the levator ani, piriformis and obturator internus muscles, so as to identify trigger points on the pathway of the synthetic mesh (EO). Pelvic floor muscle training with muscle relaxation is recommended when myofascial pain syndrome is associated with chronic postoperative pain following POP surgery (EO). After failure of pelvic floor muscle training (3 months), it is recommended to discuss surgical removal of the synthetic mesh, during a multidisciplinary discussion group meeting (EO). Partial removal of synthetic mesh is indicated when a trigger point is located on the pathway of the mesh (EO). Total removal of synthetic mesh should be discussed during a multidisciplinary discussion group meeting when diffuse (no trigger point) chronic postoperative pain occurs following POP surgery, with or without central sensitization or neuropathic pain syndromes (EO). POSTOPERATIVE DYSPAREUNIA: When de novo postoperative dyspareunia occurs after POP surgery, surgical removal of the mesh should be discussed (EO). VAGINAL MESH EXPOSURE: To reduce the risk of vaginal mesh exposure, when hysterectomy is required during sacral colpopexy, subtotal hysterectomy is recommended (grade C). When asymptomatic vaginal macroporous monofilament polypropylene mesh exposure occurs, systematic imaging is not recommended. When vaginal polyester mesh exposure occurs, pelvic +/- lumbar MRI (EO) should be used to look for an abscess or spondylodiscitis, given the greater risk of infection associated with this type of material. When asymptomatic vaginal mesh exposure of less than 1 cm2 occurs in a woman with no sexual intercourse, the patient should be offered observation (no treatment) or local estrogen therapy (EO). However, if the patient wishes, partial excision of the mesh can be offered. When asymptomatic vaginal mesh exposure of more than 1 cm2 occurs or if the woman has sexual intercourse, or if it is a polyester prosthesis, partial mesh excision, either immediately or after local estrogen therapy, should be offered (EO). When symptomatic vaginal mesh exposure occurs, but without infectious complications, surgical removal of the exposed part of the mesh by the vaginal route is recommended (EO), and not systematic complete excision of the mesh. Following sacral colpopexy, complete removal of the mesh (by laparoscopy or laparotomy) is only required in the presence of an abscess or spondylodiscitis (EO). When vaginal mesh exposure recurs after a first reoperation, the patient should be treated by an experienced team specialized in this type of complication (EO). SUTURE THREAD VAGINAL EXPOSURE: For women presenting with vaginal exposure to non-absorbable suture thread following POP surgery with mesh reinforcement, the suture thread should be removed by the vaginal route (EO). Removal of the surrounding mesh is only recommended when vaginal mesh exposure or associated abscess is diagnosed. BLADDER AND URETERAL MESH EXPOSURE: When bladder mesh exposure occurs, removal of the exposed part of the mesh is recommended (grade B). Both alternatives (total or partial mesh removal) should be discussed with the patient and should be debated during a multidisciplinary discussion group meeting (EO).

Prostate interventions in patients with mild haemophilia: Safe and feasible.

INTRODUCTION: To date, there is no specific recommendation or evaluation of the morbidity of prostate surgery in patients with haemophilia (PWH) although this surgery is common and at high risk of bleeding. AIM: To assess the post-operative morbidity of benign prostate hyperplasia (BPH) surgeries and of oncological prostate interventions in patients with mild haemophilia A or B. METHODS: We performed a monocentre, epidemiological, in real life study. Data were collected between 1 January, 1997 and 1 September, 2020 and focused on prostate biopsy, radical prostatectomy, prostate radiotherapy, simple prostatectomy, transurethral resection of prostate (TURP) and laser-vaporisation in patients with mild haemophilia A or B. RESULTS: Between 1 January, 1997 and 1 September, 2020, 51 interventions were performed on 30 patients with mild haemophilia. Haemophilia A represented 93.33% of the population and haemophilia B 6.67%. For prostate biopsies (n = 24), median length of hospitalisation was 4 days and only one patient needed a blood transfusion. No patient needed re-admission. For prostatectomy (n = 10), one patient presented with intra-operative and post-operative bleeding. Two patients required re-admission. The other patients did not present any significant haemorrhagic symptoms. For radiotherapy (n = 4), two patients presented a grade II complication (radiocystitis and radiorectitis). For BPH surgeries, during hospitalisation, laser-vaporisation (n = 5) was less haemorrhagic than TURP (n = 5) but after hospital discharge, 60% of patients presented a haemorrhagic complication with two readmissions and one surgical re-explorations. CONCLUSION: Performed in a specialised centre, prostate surgeries and interventions in patients with mild haemophilia is feasible with acceptable morbidity.

Benign Prostatic Hyperplasia Endoscopic Surgical Procedures in Kidney Transplant Recipients: A Comparison Between Holmium Laser Enucleation of the Prostate, GreenLight Photoselective Vaporization of the Prostate, and Transurethral Resection of the Prostate.

Purpose: The main objective of this multicentric retrospective pilot study was to evaluate the 1-year follow-up safety (i.e., minor [Clavien-Dindo I-II] and major [Clavien-Dindo ≥III] complications) of holmium laser enucleation of the prostate (HoLEP), GreenLight photoselective vaporization of the prostate (GL PVP), and transurethral resection of the prostate (TURP) performed after kidney transplantation (KT). The secondary objectives were to evaluate the efficacy and to assess the impact of these procedures on graft function. Materials and Methods: We retrospectively included all KT recipients who underwent a HoLEP or GL PVP or TURP for benign prostatic hyperplasia (BPH) in three French university centers. Results: From January 2013 to April 2018, 60 BPH endoscopic surgical procedures in KT recipients were performed: 17 HoLEP (HoLEP group), 9 GL PVP (GL PVP group), and 34 TURP (TURP group). Age, body mass index, preoperative serum creatinine, preoperative International Prostatic Symptom Score, preoperative Qmax, preoperative prostate-specific antigen, medical history of acute urinary retention (AUR), urinary tract infection (UTI), and indwelling urethral catheter were similar in all study groups. Mean preoperative prostate volume was higher in HoLEP group. The rate of overall postoperative complications was statistically higher in the HoLEP group (11/17 [64.7%] vs 1/9 [11.1%] vs 12/34 [35.3%] in HoLEP group, GL PVP group, and TURP group, respectively, p = 0.02), with higher rate of long-term UTI and AUR. Qmax improved in all groups after operation. Delta postoperative month 12-preoperative serum creatinine was similar in the all groups. Conclusions: Although our study is underpowered, the rate of postoperative complications is higher with HoLEP procedure, in comparison with GL PVP, for the treatment of BPH after KT. One-year efficacy is similar in HoLEP, GL PVP, and TURP groups. Further prospective randomized controlled trials are needed to confirm our results.

[Diagnosis and treatment of penis cancer]. / Diagnostic et traitement du cancer du pénis.

Penile cancer is a rare tumor in Europe and is therefore associated with risks of diagnostic delay for stage Ta-T1 tumors or pre-epitheliomatous lesions and of an inadequate treatment strategy. Clinical examination by palpation is essential in primary tumors to look for infiltration in the corpus spongiosum and the tunica albuginea of the corpus cavernosa of the penis, and in the lymphatic drainage areas, in particular in the upper inner quadrant of the inguinal lymph nodes. The work-up must include: a biopsy in the case of diagnostic doubt, lymph node aspiration in the case of palpable adenopathies, and whole-body computed tomography (CT). Treatment of the primary tumor can include partial amputation for tumors infiltrating the corpus cavernosa, or conservative treatment for tumors limited to the glands if the diameter is less than 30 mm, after an initial circumcision. Groups at risk of lymph node metastases have been defined as a function of the pathology results of their primary tumors. In these groups at risk, or in the case of clinical lymph node metastasis, dissection of the lymph node has an important role, permitting 5-year survival rates greater than 80 % when the number of metastatic lymph nodes is ≤ 1-2. In the case of more extensive lymph node spread, a combination of chemotherapy and surgery must be discussed in multidisciplinary meetings, especially for younger patients.

[Study of the efficacy and medium-term complications of 41 sacral nerve neurostimulators (Interstim, Medtronic, U.S.A.) in refractory urinary disorders]. / Etude sur l'efficacité et les complications à moyen terme de 41 implantations de neuromodulateur des racines sacrées (Interstim, Medtronic, U..S.A.) dans les troubles urinaires réfractaires.

OBJECTIVE: Single-centre retrospective follow-up study (short-term and medium-term efficacy, complications, revisions) of patients treated for refractory urinary disorders by sacral nerve neurostimulation (Interstim, Medtronic, U.S.A.). MATERIAL AND METHOD: A sacral nerve neurostimulation screening test was performed in 79 patients with refractory urinary disorders between 1999 and 2005 and a neurostimulator was implanted in 41 of these patients. Patients were evaluated by bladder diary, MHU urinary disability score, and urodynamic assessment. RESULTS: The mean follow-up was 20.5 months. A significant improvement of bladder diary parameters and MHU urinary disability score was observed at 6, 12, and 24 months of follow-up. At 20.5 months, 22 (54%) patients were considered to be failures and 3 were explanted. Five patients were considered to be a success, and 14 were improved, i.e. 19 (46%) success/improvement at 20.5 months of follow-up. The only predictive factor of success was a history of symptoms lasting less than 5 years before neurostimulator implantation. A complication was observed in 70% of patients. More than one half of patients reported pain at some time during follow-up. Four infections were observed, one of which required explantation. Ten technical problems due to accidental deactivation or interference with a magnetic field were observed. Seven patients (17%) required revision: repositioning of the leads due to inefficacy in 3 cases, and change of position of the device in 4 cases. CONCLUSION: Sacral nerve neurostimulation is an effective treatment in refractory urinary disorders in more than 45% of implanted patients, although this effect tends to wane over time. Our results are less favourable than those described in the literature, but were based on stricter endpoints. A high complication rate, mainly pain, was observed, but most required only symptomatic management. This technique nevertheless remains a good alternative to invasive surgical management of functional disorders.
