[Robot-assisted laparoscopic bladder diverticulum resection (RABDR)]. / Roboterassistierte Harnblasendivertikelresektion (RAHDR).

AIMS: Since October 2018, urinary bladder diverticulum resections at our Department of Urology have been carried out with robot assistance and with minimal invasivion, Paediatrical urological and robot-assisted minimally invasive urological surgery for the Bamberg Social Foundation were performed with the DaVinci robotic systemTM. The aim of the present study was to record the surgical results of our patients and to compare these if necessary with available data on optimal diagnostic and therapy. METHODS: In this retrospective analysis, we included all patients who received RAHDR between October 2018 and March 2020. The primary endpoints were postoperative blood loss (postoperative haemoglobin decrease), the operation time (min), complications according to the Clavien-Dindo classification, length of hospital stay (days), postoperative residual urine, postoperative urine extravasation at the anastomosis of the bladder, postoperative quality of life and postoperative satisfaction with micturition. RESULTS: We reviewed a total of 11 patients, all of whom were male. Mean age was 64.8 years (52-82). Average BMI was 26.5 (19-37). 3 patients were ranked with ASA score III, 5 with II and 3 with I. The average residual urine value preoperatively was 183 ml (90-240). A cystogram to rule out extravasation was performed on day 6 postoperatively. The mean duration of surgery was 212 min (148-294) and the mean duration of hospitalisation was 7.6 days (6-10). The mean residual urinary value after surgery was 25 ml (10-60). The mean postoperative maximum of flow was measured at 27.7 ml/s (11-55). No contrast agent extravasation in the cystogram was detected in any of the patients. The complications according to Clavien were not measurable. The mean postoperative haemoglobin decrease was 1.61 g/dl (0-3. 2). CONCLUSIONS: In most cases, the removal of one or more bladder diverticula is possible using the minimally invasive robotic technique. Various surgeries such as YV-bladder neck plastic, prostate adenoma enucleation, bladder stone restoration, and inguinal herniotomy can be carried out simultaneously. A robot-assisted urinary bladder diverticulum resection is an effective and gentle procedure. However, it must be considered that it brings financial disadvantages due to the lack of adequate representation within the German DRG-system (Diagnosis Related Groups).

[A rare case of renal ectopic thyroid tissue]. / Ein seltener Fall eines renalen ektopen Schilddrüsengewebes.

We present a rare case of ectopic thyroid tissue found during robotic nephrectomy of a kidney with a suspected malignant tumour. Such cases of ectopic thyroid tissue are extremely rare in the literature. If ectopic thyroid tissue occurs, it is usually found in the neck region or in the upper mediastinum. Clinical symptoms depend on size, localisation and hormonal function of the ectopic tissue. Surgical resection remains the treatment of choice; in individual cases, conservative treatment can be an option. This case report aims to emphasise that renal tumours of unknown origin might be paraneoplastic or ectopic tissue of other organs.
