We aimed to review studies on laser enucleation of the prostate (LEP) due to LUTS in elderly patients (> 65 years) comparing different age groups, particularly considering functional outcomes, safety, and perioperative complications. A comprehensive search was conducted using the PubMed-MEDLINE, Web of Science, Wiley Online Library and Cochrane Library databases over the last 10 years until 7 October 2021 with the following search terms solely or in combination: “laser enucleation”, “prostate”, “laser prostatectomy”, “aging”, “elderly patients”, “older patients” and “age”. We identified 12 articles for inclusion in our analysis. Five studies focussed mainly on holmium laser enucleation of the prostate (HoLEP), one compared HoLEP to other laser prostatectomy procedures, two studies examined thulium laser enucleation of the prostate (ThuLEP), and two studies focused on GreenLight laser, one study focussed on potassium-titanyl-phosphate (KTP) laser, and another study compared laser prostatectomy to transurethral resection of the prostate (TURP). These studies showed that LEP improved IPSS, Qmax and QoL compared to baseline regardless of age; no significant difference was reported among age groups. Although ASA scores and anticoagulation/antiplatelet therapy rates are higher in elderly patients, studies revealed no significant difference in perioperative complication rates between age groups. Laser enucleation of the prostate is an effective and safe procedure in elderly patients, resulting in good functional outcomes, low morbidity, and few perioperative complications.Keywords: aged, benign prostatic hyperplasia, elderly patients, HoLEP, laser enucleation of the prostate

Abstract Objectives and Aims To compare guideline recommendations with daily practice patterns in a German patient cohort with renal cell carcinoma. Patients and methods 81 patients with T1 oder T2 renal cell carcinoma (RCC) were included in this prospective single-center study. All patients were operated in a single institution either by open radical nephrectomy (ORN) or nephron sparing surgery (NSS). Patients and doctors were evaluated using a written questionnaire with a follow-up of 12 months. Follow-up intervals, follow-up modalities (e. g. imaging modalities, laboratory controls of blood and urine) and the call on psycho-oncological support were evaluated. Results The majority of patients (72%) were followed up by their urologists. Follow-up examinations included abdominal ultrasound, urine and blood diagnostics, conventional chest x-rays, computed tomography (CT) of abdomen, chest or head or abdominal Magnetic Resonance Imaging (MRI). There were no significant differences between patients operated by ORN or NSS. In total, 12.5% of patients were asking for psycho-oncological support. Conclusions In general, patients were followed up according to existing guideline recommendations. Only a small proportion of patients asked for psycho-oncological treatment.

Abstract Objectives and aims To avoid damage to the ureters during bladder neck preparation in radical prostatectomy for prostate cancer, it may be helpful to insert ureteral stents temporarily or to intravenously administer indigo carmine dye for enhanced visualisation of ureteric orifices. We evaluated our bladder neck preserving technique at radical prostatectomy with regard to ureteric injuries. Patients and methods We analysed 369 consecutive radical prostatectomies operated in our clinic in a bladder neck preserving technique. The following parameters were assessed in this retrospective study: number of prophylactic ureteric stent insertions, application of indigo carmine dye, observed injuries of the ureters by the surgeon, postoperative increase of serum creatinine and postoperative status of kidney ultrasound. Results In 7/369 prostatectomies (1.90%) a ureteric stent insertion was performed, indigo carmine was not applied to any patient at all, yet no intraoperative injury of a ureter was observed by a surgeon. No revision was necessary due to a ureteral injury within the observation period of one year after surgery. In 17 patients with preoperative normal creatinine value a pathological value was observed on the first postoperative day (mean 1.4 mg/dl). In these patients no consecutive postrenal acute renal failure was observed, no hydronephrosis was monitored by ultrasound and no further intervention was necessary. Conclusions Bladder neck preserving operation technique does not implicate the need of prophylactic ureteric stent insertions and has no higher incidence of ureteric injuries.
