Study Design: prospective, observational.
Background: Wound drainage's indwelling duration and general use are the centre of ongoing discussion. The aim of our prospective observational study was to evaluate the total drainage volume postoperatively and its course after lumbar interbody fusion surgeries to define an ideal point in time for drainage removal.
Methods: We included all patients who underwent monosegmental lumbar interbody fusion via transforaminal or posterior lumbar interbody fusion (TLIF/PLIF). After application of the exclusion criteria, 27 patients were included in our study. Drainage volume was measured three times a day and at the time of drain removal.
Results: The PLIF group reached higher total drainage volume (337.14 ml) than the TLIF group (215.5 ml) (p = 0.047. Drainage volume's plateau was reached after 33.0 h (±1.8 h) in the TLIF group and 25.3 h (±1.7 h) in the PLIF group following surgery.
Conclusions: Our study shows, that drainage volume did not increase significantly after the evening of the first postoperative day at latest. This was on average 33.0 h after surgery. Therefore, extraction of the drainage tube hereafter can be assumed to be safe.

The motion of the trabecular meshwork (TM) facilitates the aqueous drainage from the anterior chamber to the venous system, thereby maintaining normal intraocular pressure. As such, characterizing the TM motion is valuable for assessing the functionality of the aqueous outflow system, as demonstrated by previous phase-sensitive optical coherence tomography (OCT) studies. Current methods typically acquire motion from a single cross-sectional plane along the circumference of the anterior chamber.

Aim: Timing of chest tube removal post lung resection is variable in practice and often based on personal experience rather than evidence. The current practice in chest tube management among thoracic surgeons across Canada is so far unknown. Our primary aim was to assess the current status of chest tube removal in Canada in order to uncover potential shortcomings.

BACKGROUND Surgery involving the right retroperitoneum can result in lymphatic (chylous) leakage from the cisterna chyli located anterior to the L1 and L2 vertebra or from lymph node dissection. This report describes a 46-year-old woman with retroperitoneal lymphatic (chylous) leak following right adrenalectomy for a nonfunctional adrenal adenoma. CASE REPORT A 46-year-old woman presented with a medical history of hypertension.

Quantifying pleural effusion change on chest CT is important for evaluating disease severity and treatment response. The purpose of this study was to assess the accuracy of artificial intelligence (AI)-based volume quantification of pleural effusion change on CT images, using the volume of drained fluid as the reference standard. Seventy-nine participants (mean age, 65 ± [SD] 13 years; 47 male) undergoing thoracentesis were prospectively enrolled from October 2021 to September 2023.

In the clinical setting, individuals with neurogenic bladder dysfunction commonly utilize indwelling urinary catheters for urinary management. The comparative efficacy of catheter clamping versus continuous free drainage in this patient population is yet to be established. This meta-analysis aims to explore the efficacy and safety of catheter clamping versus natural drainage in patients with neurogenic bladder, to provide evidence to support the treatment and nursing care of these patients.
