Purpose: Adequate position of the bone block during arthroscopic Latarjet procedure is critical for an optimal functional outcome. However, this procedure is complex with a long learning curve. Our aim was to compare the bone block position between a dedicated glenoid posterior instrumentation and suture button fixation versus an anterior screw fixation, on a postoperative computed tomography (CT) scan.

Background: Widespread adoption of the AMS-800 artificial urinary sphincter (AUS) in female patients has been hampered by the surgical morbidity of its implantation through an open approach.

Objective: To describe a standardized technique of robotic bladder neck AUS implantation in female patients, and to report the perioperative and functional outcomes obtained by multiple surgeons with this technique.

Design, Settings, And Participants: We retrospectively reviewed the charts of all female patients who underwent robotic AUS implantation for urinary incontinence due to intrinsic sphincter deficiency between March 2012 and March 2017 in five institutions.

Aim: To analyse current practice patterns and to evaluate (long-term) effectiveness and adverse events of sacral neuromodulation with InterStim™ Therapy based on data collected in a national register and to discuss the strengths and weaknesses of the register.

Patients And Methods: This is a French multicenter prospective observational trial including patients with a permanent implant (2003-2009). Voiding diary variables and patient satisfaction were analysed based on last follow-up visit since implantation.

Twenty-three patients having undergone enterocystoplasty with a detubulated graft has an urodynamic study on an empty stomach and after a standardized meal. All patients (average age 62.9 years) had been operated more than 6 months earlier, and 30% still presented with urine leakages at night.

Between March 1988 and February 1991, 47 patients with urinary stress incontinence (USI) were treated by Gittes' operation, suspension thread traction being determined by perioperative ultrasonography in 31 of these cases. All patients were re-examined on February 1992 after a mean follow-up of 26 months (range 12 to 24 mths). The global success rate (recovery and improvement) was assessed as 72% at 3 months and 56% at follow-up.

Forty-five patients with 46 ureteral stones were treated using a new pulsed dye laser (Pulsolith, TMI). A fiber of 250 micrometers was used through rigid (40 cases) or flexible (6 cases) ureteroscopes. Stones were located in the upper third (5 cases), middle third (5 cases), or lower third (36 cases) of the ureter.

Thirty-two patients with ureteral calculi ranging in size from 5 x 5 to 12 x 18 mm underwent lithotripsy with a new pulsed dye laser (Pulsolith, TMI). In 24 cases, the patients were entirely free of stones following laser lithotripsy alone, or with adjunctive stone basket removal. There were three instances of equipment failure and five calcium oxalate monohydrate stones that did not respond to laser energy.

We treated 47 patients with transitional cell bladder carcinoma invading the lamina propria (stage T1) from 1984 to 1986 with complete transurethral resection followed by one to three courses of endovesical BCG instillation and followed them for 14-64 months with cystoscopic and endoscopic tests and bladder biopsy. Complete response was achieved in 64%, and 36% had recurrences (recurrence rate per 100 month/patient, 2.2); 21% progressed to muscle invasion.

Thirty-four children, ten of them coming from another Surgical Center, underwent repair for urethral fistula after hypospadias reconstructive surgery, over a period of three years (1985-1987). After the first operation, there was no recurrence in 59% (20 cases). Currently, all fistulas have been closed, except in 3 cases.

47 patients with transitional cell bladder carcinoma invading the lamina propria (stage A/T1) were treated from 1984 to 1986 by complete transurethral resection followed by 1-3 cycles of endovesical bacillus Calmette-Guérin instillations, and followed 14-64 months by cytology, endoscopy and bladder biopsies, 64% achieved a complete response, 36% recurred (recurrence rate/100 months/patient 2.2), 21% progressed to muscle invasion.

Seventy-four hydronephrosis by uretero-pelvic obstruction, discovered by antenatal real-time ultrasound, have been managed on sixty-one children. Three groups, with a specific management, are distinguished. The minimal forms have been only watched over (15 cases).

Fourteen cases of obstruction after ureteroneocystostomy in children have been cured by surgery between 1972 and 1986; nine patients were referred from outside our hospital. This failure as been observed after reimplantation of simple thin ureter (29 cases) megaureter (7) or duplication (4). The diversity of lesions, of which 52 percent were ischemic stenosis, required surgery without any preconceived idea.

Between 1977 and 1984, a total of 23 patients with post-anastomotic stenosis after surgery for esophageal atresia were treated conjointly by the ORL and digestive surgery departments of Hôpital Trousseau, France. Most cases were type III atresias treated by direct anastomosis, favoring factors for stenosis being gastro-esophageal reflux, post-anastomotic fistula and the surgical act. Stenosis usually develops early, provokes only moderately severe symptomatology and requires treatment by dilatation mainly, in association with anti-reflux medication.

Repeated catheterisation and drugs with a pharmacodynamic action are not always able to ensure perfect continence in children with meningomyeloceles. To treat uncontrollable incontinence, the authors propose an aponeurotic suspension of the bladder neck as described by Goebbel-Stoeckel in order to increase the peripheral resistance. At the same time, sufficient bladder compliance can also be obtained either by means of pharmacodynamic treatment or by enlargement enterocystoplasty.

Mostly the ectopic ureter belongs to the upper pole in urinary tract duplications. In the pelvis, the two ureters are clearly separated. The only dissection of the ectopic ureter is in no case dangerous for the ureter of the lower pole.

Three cases of epidermoid cyst of the spleen treated by partial splenectomy are reported on children. The diagnosis rests now on the ultrasonography. The operative indication is systematic because of the risks of complication.

Ultrasonography has profoundly modified the diagnostic conditions of polycystic renal dysplasia in children. Non-palpable forms, which were previously most frequently missed, can now be detected during the antenatal period. In infants, ultrasonography generally provides a definite diagnosis, which can be confirmed by aspiration-opacification of the cysts.
