[Minimally invasive treatment options for the management of benign prostatic hyperplasia]. / Minimal-invasive Therapieoptionen zur Behandlung des benignen Prostatasyndroms.

Benign prostatic hyperplasia is one of the most common diseases of aging men. Hyperplasia of the glandular tissue can cause distressing lower urinary tract symptoms, which can be treated with both drugs and interventions. For a long time, transurethral resection of the prostate and simple prostatectomy were considered the gold standard of surgical treatment. In order to be able to offer patients an outpatient treatment with few complications, shorter hospital stays and high efficiency, a variety of minimally invasive treatment options have been developed. While recommendations have already been made for the excision by focused waterjet, prostatic urethral lift, and prostatic artery embolization, there are several other very promising procedures for which, however, long-term data and data from comparative studies with reference procedures must still be awaited.

[Enhanced imaging in urological endoscopy]. / Erweiterte Bildgebung in der urologischen Endoskopie.

White light cystoscopy and the concise documentation of pathological findings are standard diagnostic procedures in urology. Additional imaging modalities and technical innovations may support clinicians in the detection of bladder tumors. Modern endoscopy systems provide ultra-high-resolution imaging and the option of digital contrast enhancement. Photodynamic diagnostics and narrow band imaging are well-established in clinical routine and have shown significant benefits in the detection of bladder cancer. By means of multispectral imaging, different modalities can now be combined in real-time. Probe-based procedures such as optical coherence tomography (OCT) or Raman spectroscopy can further contribute to advanced imaging through an "optical biopsy" which may primarily improve diagnostics in the upper urinary tract. The aim of all techniques is to optimize the detection rate in order to achieve a more accurate diagnosis, resection and lower recurrence rates. Current research projects aim to digitalize the documentation of endoscopy and also make it more patient- and user-friendly. In the future, the use of image processing and artificial intelligence may automatically support the surgeon during endoscopy.
