The Holmium:YAG laser has been the gold standard for laser lithotripsy over the past three decades and, since the late 1990s, also for prostate enucleation. Pulsed thulium fibre lasers (TFL) demonstrated their efficacy in in-vitro experiments and were introduced to the market a few years ago. Initial clinical results for TFL in lithotripsy and enucleation are very promising. In addition to TFL, a pulsed Thulium:YAG solid-state laser has been introduced, but clinical data for this laser are currently limited. This article aims to review the key technological differences between Ho:YAG lasers and pulsed thulium lasers and compare/discuss the initial clinical results for stone lithotripsy and laser enucleation.In-vitro studies have demonstrated the technical superiority of TFL compared with Ho:YAG lasers. However, as TFL is still a new technology, only limited studies are available to date, and optimal settings for lithotripsy have not been established. For enucleation, the differences of TFL compared with a high-power Ho:YAG laser seem to be clinically irrelevant. Initial studies on pulsed Tm:YAG lasers show good results, but there continues to be a lack of comparative studies.Based on the current literature, pulsed thulium lasers have the potential of being an alternative to Ho:YAG lasers. However, further studies are necessary to determine the optimal laser technology for enucleation and lithotripsy of urinary stones, considering all parameters, including efficacy, safety, and cost., Competing Interests: Die Autorinnen/Autoren geben an, dass kein Interessenkonflikt besteht., (Thieme.

The need for intervention due to postoperative bleeding represents a significant complication in Thulium Laser Enucleation of the Prostate (ThuLEP). This study aimed to retrospectively analyse this complication in the treatment of benign prostatic enlargement. This study focuses on investigating potential causative factors for postoperative bleeding requiring intervention as well as the use of intraoperative electrocoagulation. A total of 503 ThuLEP procedures performed between 08/2021 and 07/2022 were examined. Postoperatively, 4.2% (n=21) of patients experienced bleeding requiring intervention. Study data revealed a significant association between these instances of bleeding and a high prostate volume (p=0.004), high enucleation weight (p=0.004), and intraoperative electrocoagulation (p=0.048). In total, intraoperative electrocoagulation was applied in 41.2% (n=207) of cases. In these cases, statistically significant factors leading to the application of electrocoagulation included intraoperative capsule perforation (p=0.005) and high enucleation weight (p=0.002)., Competing Interests: Die Autorinnen/Autoren geben an, dass kein Interessenkonflikt besteht., (Thieme.

Introduction: Adult hydrocele is a benign enlargement of the scrotum seen in approximately 60/100,000 men >18 years of age. Surgical resection of the hydrocele has been established as the gold standard for the treatment of symptomatic hydroceles. Postoperative complications are common with this surgery. Due to the lack of guidelines for the therapy of hydrocele, treatment is based primarily on clinical experience. The aim of the study was to conduct a randomised study on the influence of drains on complications in hydrocele resection according to von Bergmann., Material and Methods: A total of 60 patients were prospectively randomised into three groups. The groups each received an Easy-Flow drainage, a Cuti-Med Sorbact drainage, or no drainage. Haematoma and swelling, postoperative bleeding, infection, epididymal injury and revision surgery were clinically diagnosed as complications., Results: A complication was observed in 31.6% (n=19/60) of all patients. The complication rate was 50% (n=10) for the easy-flow drainage, 30% (n=6) for the Cuti-Med-Sorbact and 15% (n=3) for the group without drainage. Overall, a haematoma with swelling was observed most frequently, in 20% (n=12) of the cases. Revision surgery was required in 5% (n=3) of cases. Epididymal injuries were found histologically in 10% (n=6). Comparing the collective with the Easy-Flow drainage with the collective without drainage, the occurrence of complications was observed significantly more frequently in the drainage group (p<0.018). A statistically significant correlation regarding complications between the group of Cuti-Med-Sorbact and no drainage could not be shown (p<0.25)., Conclusions: Hydrocele resection is a complicated procedure. Based on the data presented here, the insertion of a drain is associated with an increased risk of postoperative complications. If the decision to insert a wound drainage is made intraoperatively, the Cuti-Med-Sorbact drainage appears to be associated with fewer complications., Competing Interests: Die Autorinnen/Autoren geben an, dass kein Interessenkonflikt besteht., (Thieme.
