The impact of type 1a endoleak on the long-term outcome after EVAR.

OBJECTIVE: Endoleaks remains a major determinant of outcome after endovascular aortic repair (EVAR) for infrarenal abdominal aortic aneurysms. The objective of this study is to evaluate the long-term impact of proximal type 1 endoleak encountered at the case end of the EVAR procedure or during follow-up. METHODS: All patients treated with EVAR between February 2001 and August 2017 in our institution were included. Data were collected retrospectively. A descriptive analysis of subgroups with type 1a endoleak at case end or with type 1a endoleak first encountered during follow-up was performed. RESULTS: In total, 468 patients were included for analysis. At the case end of the EVAR procedure, in 5.3% (25/468) of patients, a type 1a endoleak was seen. In 72% of cases (18/25) the type 1a endoleak spontaneously disappeared on the first follow-up computed tomography angiography and never recurred. At the end of the follow-up period, no patient in this subgroup died with a type 1a endoleak on follow-up. In 3.4% (16/468) of all cases, a type 1a endoleak was encountered for the first time during follow-up. In 87.5% (14/16) of these cases, reintervention was performed. Two patients died with a persisting type 1a endoleak during follow-up. CONCLUSIONS: Clinicians should differentiate between the type 1a endoleak at the case end and the type 1a endoleak first occurring during follow-up. For type 1a endoleak at the case end, expectant management can be adopted. Delayed type 1a endoleak seen during follow-up rarely seals spontaneously and needs reintervention in the majority of cases.

Safety and efficacy of software-assisted MRI-TRUS fusion-guided transperineal prostate biopsy in an outpatient setting using local anaesthesia.

PURPOSE: To evaluate diagnostic accuracy, safety, and efficiency of an MRI-TRUS fusion-guided transperineal prostate biopsy method in an outpatient setting under local anaesthesia. METHODS: Patients undergoing transperineal prostate biopsy were included from March 2021 to May 2022. Biopsies were performed under local anaesthesia in an outpatient setting, using specialised fusion software. Primary outcome was (clinically significant) cancer detection rate. Secondary outcomes were procedure time, patient discomfort during the procedure and complication rate. RESULTS: We included 203 male patients (69 years +-SD 8.2) with PI-RADS score > 2. In total 223 suspicious lesions were targeted. Overall cancer detection rate and clinically significant cancer detection rate were 73.5% and 60.1%, respectively. (Clinically significant) cancer detection rates in PI-RADS 3, 4 and 5 lesions were 46.4% (23.2%), 78.5% (66.1%) and 93.5% (89.1%), respectively. Mean duration of the procedure including fusion, targeted and systematic biopsies was 22.5 min. Patients rated injection of local anaesthesia on a numeric pain rating scale on average 3.7/10 (SD 2.09) and biopsy core sampling 1.6/10 (SD 1.65). No patient presented with acute urinary retention on follow-up consultation. Two (1%) patients presented with infectious complications. Four (2%) patients experienced a vasovagal reaction. CONCLUSION: Transperineal targeted biopsy with MRI-TRUS fusion software has high overall and clinically significant cancer detection rates. The method is well tolerated under local anaesthesia and in an outpatient setting.

Irrigation fluid absorption syndrome during HoLEP: A case study.

The classical transurethral resection syndrome as described with monopolar prostate resection has become rare since the switch to bipolar resection and even more so since the introduction of HoLEP. We report a case of a 74-year-old male patient who presented with an irrigation fluid absorption syndrome during a HoLEP for benign prostate hypertrophy. Biochemically this presented as metabolic acidosis and hyperchloremia instead of hyponatremia. He was treated with diuretics and had a swift recovery.

Current role of cytoreductive nephrectomy in metastatic renal cell carcinoma.

Historically, immediate cytoreductive nephrectomy (CN) was considered the standard of care in patients with metastatic renal cell carcinoma (mRCC) who were fit enough to undergo surgery. Recently, 2 randomized controlled trials, SURTIME and CARMENA, have questioned the role of immediate CN and initiated an ongoing debate on the proper indications and timing of CN. Although some patients still benefit from immediate CN, other patients require immediate systemic treatment, and some of them might benefit from deferred CN in the absence of disease progression. This study provides an overview of the history of CN, an in-depth analysis of SURTIME and CARMENA, and highlights the current indications for performing immediate or deferred CN.
