Background: The surgical management of benign prostatic obstruction (BPO) has greatly evolved in recent years.

Objectives: The aim of this study is to present contemporary management and trends for surgical BPO therapy in Germany.

Materials and methods: Disease and procedure rates were extracted using the online platform reimbursement.INFO that is based on German hospital quality report data. For the diagnosis of benign prostate hyperplasia (BPH), the ICD codes N40 and D29.1 were used. For evaluation of the surgical procedures OPS codes 5‑600.0, 5‑601, 5‑603, 5‑609.4 and 5‑609.8 including their subcodes were used. In addition to descriptive analyses, trend and correlation analyses were performed.

Results: In 2019, a total of 83,687 procedures for BPO in 473 urological departments were performed. The most common (71.7%) surgery was transurethral resection of the prostate (TUR-P). Holmium laser enucleation of the prostate (HoLEP; 9.5%) and surgical adenomectomy (5.6%) were the second and third most common procedures. Less often thulium laser enucleation (ThuLEP; 3.1%), laser vaporisation (2.9%) and electrical vaporisation (2.8%) were performed. All other techniques were performed in < 1%. Rates of HoLEP, ThuLEP and electrovaporisation have increased since 2006 (HoLEP: +42.42%/year, p < 0.001; ThuLEP: +20.6%/year, p = 0.99; electrovaporisation +43.42%/year, p < 0.001), while surgical adenomectomy decreased (-1.66%/year, p < 0.01). In 2019 mean length of hospital stay was 5.1 ± 0.1 days.

Conclusions: TUR‑P remains the most often performed surgical treatment for BPO. Laser therapy-especially in centers-is increasing, while surgical adenomectomy continues to abate.

Infections in patients with neutropenia following chemotherapy are mostly manifested as fever (febrile neutropenia, FN). Some of the most important determinants of the risk of FN are the type of chemotherapy, the dose intensity and patient-specific factors. When the risk of FN is 20% or more granulopoiesis is prophylactically stimulated with granulocyte colony stimulating factor (G-CSF) after the treatment. Anemia should always be clarified and if necessary be treated according to the cause when symptomatic. If an absolute or functional iron deficiency is present, intravenous iron substitution is mostly necessary. Erythropoiesis-stimulating agents can be used after chemotherapy with hemoglobin (Hb) levels less than 10 g/dl (6.2 mmol/l). In cases of chronic anemia and Hb levels less than 7-8 g/dl (<4.3-5.0 mmol/l) the indications for transfusion of erythrocyte concentrates should be assessed primarily based on the individual clinical symptoms.

Concerning follow-up in bladder cancer, it must be distinguished between superficial, muscle-invasive, and metastatic tumors. In superficial bladder cancer, urethrocystoscopy is still standard for follow-up. Frequency depends on the risk classification. Even muscle-invasive carcinomas, which underwent a R0 resection, will metastasize in about 30% of cases. These tumors as well as primarily metastasized cancer cannot be cured. Therefore, in these cases, one should not speak about follow-up but therapeutic control. Nonetheless, even in these cases the S3 guideline recommends regular follow-up examinations because new therapeutic options can clearly improve patient survival. Possible complications of urinary diversions need consideration during follow-up.

We report on two patients who were in initially circulatory stable condition with grade IV kidney trauma after knife stab accident. Patient 1 underwent reconstructive surgery to retrieve a broken knife blade, while patient 2 was treated conservatively for bleeding that did not require intervention. Both patients could ultimately be discharged in stable condition. These case studies show that even in the case of high-grade kidney trauma with the appropriate constellation of findings, conservative management and, if exploration is necessary, a reconstructive approach is possible.

Background: Even though robot-assisted operations have evolved to a standard procedure in surgery, they are underrepresented in the curriculum of current medical students.

Objectives: We present our experience and findings in Germany's first elective "Robot-assisted surgery" at a urological department for undergraduate medical students.

Materials and methods: Ten undergraduates in their final years were taught the theoretical basics and practical skills in robot-assisted surgery within six lessons each lasting 2 h, including the opportunity to observe a live robot-assisted surgery. The increase of knowledge (ten multiple-choice questions) and skills (exercises Camera 0, Clutch, and Sea Spikes 1) on a robotic simulation device were quantified including an evaluation of the student's perspective.

Results: The 10 participants had a significant increase in knowledge and gave at a median of 3.5 additional correct answers in the final assessment (p = 0.011). For two out of three practical exercises, the overall score significantly increased (Camera 0 and Sea Spikes 1, for both p < 0.05), but for the exercise "Clutch", only economy of motion significantly improved (p = 0.028). The elective was evaluated (very) good and the willingness of the participants to become urologists significantly increased (p = 0.007).

Conclusion: There is a great interest of many undergraduate medical students in robot-assisted surgery. Offering an elective appears to be an excellent format to teach the theoretical background and practical skills in robotic (urologic) surgery. Moreover, such an elective could raise more attention to the field of urology and might attract future colleagues.

Background: Prostate-specific membrane antigen positron emission tomography (PSMA PET) is increasingly replacing conventional imaging for staging of prostate cancer. A major challenge is its appropriate use and correct interpretation.

Objectives: How and when is PSMA PET used in patient care to optimally direct therapy?

Materials and methods: Systematic presentation and discussion of the current state of knowledge, guidelines and expert knowledge on PSMA PET with a summary of ongoing studies.

Conclusion: PSMA PET is the new standard for systemic staging of prostate cancer, enabling precision patient care with novel local, oligometastatic, and systemic treatment approaches.

The amendment to the collective agreement is intended to significantly improve the working conditions of physicians and includes longer-term duty scheduling, work on a maximum of two weekends per month, less overtime. Smaller hospitals often have problems implementing these requirements and have to make compromises. At least the overtime is now better paid-overall, an improvement in working conditions can only be achieved by increasing the number of staff, then better and more intensive training is also possible.
