[Transurethral resection of bladder tumors (TURBT)]. / Transurethrale Resektion von Blasentumoren (TUR-B).

Transurethral resection of bladder tumors (TURBT) is the standard of care for the diagnostics and primary treatment of bladder tumors. These are removed by fragmentation using loop diathermy. The resection area is coagulated for hemostasis. An important aspect is always a complete resection with an adequate amount of detrusor muscle in the specimen. Postoperative intravesical instillation of single-shot chemotherapy has been proven to reduce recurrence rates. Methods for improved tumor visualization (particularly photodynamic diagnostics) are used to enhance tumor detection rates particularly in multifocal tumors or carcinoma in situ (CIS). Thus, recurrence and progression rates can be reduced. Depending on the histological examination of the TURBT specimen, follow-up treatment for non-muscle invasive bladder tumors are adjuvant instillation treatment using chemotherapy or Bacillus Calmette-Guérin (BCG), second look TURBT and early cystectomy or for muscle invasive bladder tumors, radical cystectomy or (oncologically subordinate) trimodal treatment with renewed TURBT, radiotherapy and chemotherapy are indicated. Possible complications of TURBT include bleeding with bladder tamponade, extraperitoneal or intraperitoneal bladder perforation and infections of the urogenital tract.

[Novel surgical techniques for treatment of benign prostatic hyperplasia]. / Neue operative Techniken zur Therapie des benignen Prostatasyndroms.

In recent years new surgical techniques to treat benign prostatic hyperplasia have been introduced into urological practice and evaluated in clinical studies. Complications of standard procedures, e.g. transurethral resection of the prostate (TURP), can be avoided while maintaining equivalent clinical outcomes. The main goal is preservation of erectile and ejaculatory function. Furthermore, outpatient treatment associated with a rapid patient recovery would be desirable. This article presents the course of the interventions, the mechanisms of action and current clinical evidence for novel mechanical approaches of recanalization, water-based ablation as well as prostate artery embolization. Initial study results partially indicate that in the future practically all patients can be offered an individualized surgical technique, which provides optimal symptomatic and functional improvements with a minimized risk of complications.
