PURPOSE: Postoperative urinary retention (POUR) is a common complication after spinal surgery. However, no clear definition of POUR currently exists, and no studies have evaluated the management of POUR. We aimed to investigate the prognostic factors for eventual POUR-free status in spinal surgery patients. METHODS: The records of patients who received a urologic consultation for POUR from January 2015 to December 2016 were reviewed. POUR-free status was defined as a voiding volume (VV) >100 mL and a VV ratio >50%. Patients with an indwelling Foley catheter and those with any postoperative complications were excluded. The patients were divided into 2 groups according to the primary management method (Foley catheterization [FC] or intermittent catheterization [IC]). RESULTS: In total, 205 patients (median age, 70.6 years) were evaluated. Significant prognostic factors for eventual POUR-free status were intraoperative FC, previous spinal surgery, operative level (L3–5), lumbar fusion, and total volume (TV) at the time of POUR. Bladder training and medication did not reduce the time to POUR-free status. In patients who underwent FC, the duration of indwelling FC was a significant prognostic factor for POUR-free status. In a subanalysis, the TV (≥500 mL) and VV ratio at the time of POUR were significant prognostic factors for POUR-free status after primary management. Among the patients who achieved a POUR-free status, 8 (6.4%) experienced recurrent POUR. The VV ratio (<62.0%) was the only predictor of recurrent POUR. CONCLUSIONS: The criterion of POUR-free status is useful after spinal surgery. IC and FC were similar in their efficacy for the management of these patients.

OBJECTIVETo study the efficiency of electrocardiogram (ECG) monitor for positioning the catheter tip in the placement of peripherally inserted central catheter (PICC) in neonates.

METHODSA total of 160 neonates who were admitted to the neonatal intensive care unit (NICU) from January 2015 to December 2017 and underwent the PICC placement via the veins of upper extremity were enrolled. They were randomly divided into an observation group and a control group, with 80 neonates in each group. The neonates in the control group were given body surface measurement and postoperative X-ray localization, while those in the observation group were given body surface measurement, ECG localization, and postoperative X-ray localization. The two groups were compared in terms of general information, one-time success rate of PICC placement, and time spent on PICC placement.

RESULTSThere were no significant differences between the two groups in sex composition, gestational age, age in days at the time of PICC placement, disease type, and site of puncture (P>0.05). Compared with the control group, the observation group had a significantly higher one-time success rate of PICC placement (95% vs 79%; P<0.05) and a significantly shorter time spent on PICC placement (P<0.05). Localization under an ECG monitor during PICC placement had a sensitivity of 97% and a specificity of 100%.

CONCLUSIONSDuring the PICC placement in neonates, the use of ECG monitor to determine the position of catheter tip can improve the one-time success rate of placement and reduce the time spent on placement.

PURPOSE: The purpose of this study was to compare the effect of recirculation rate according to cannulation direction and interval among hemodialysis patients with arteriovenous fistula (AVF).METHOD: The research used repeated measures design. This study was conducted among thirty patients who received hemodialysis three times a week for longer than a year through AVF at the I University hospital. Three different types of interventions were administered to the participants each week for three weeks. Needles were placed at a different distance and in a different direction each week: 7 cm apart from each other in antegrade direction during the first week, 5 cm apart in retrograde direction in the following week, and 7 cm apart in retrograde direction in the third week.RESULTS: No significant differences in the recirculation rate were found due to any of the three tested methods (p = 1.00).CONCLUSION: This finding suggests that, if the patients have well-functioned AVF, we can choose an appropriate intervention from among the three methods in consideration of the patient's diverse needs.

Endoscopic retrograde cholangiopancreatography (ERCP) is an advanced therapeutic procedure to manage choledocholithiasis and pancreatobiliary malignancy. On occasion, ERCP failure is encountered due to difficulties in cannulation. We assessed the safety and feasibility of cap-assisted ERCP via analyzing cases in which cannulation was complicated by periampullary diverticulum. Between November 2013 and March 2014, ERCP procedures were performed in 346 patients in our tertiary medical center. Among the 73 patients who had a periampullary diverticulum, conventional ERCP failed in 5 patients due to hidden papilla (n=3) or use of tangential approach (n=2). As a rescue method, needle knife fistulotomy and selective biliary cannulation using cap-fitted forward-viewing endoscopy were successfully used in 4 patients without major complications. Based on our experience, cap-fitted forward-viewing endoscopy was relatively easy to measure the exact position of papilla and to perform biliary cannulation properly. Therefore, we recommend using cap-assisted ERCP by forward-viewing endoscopy as a useful and safe alternative to manage patients in whom cannulation is complicated by periampullary diverticulum.

Epidural venography is a relatively simple and highly accurate method in the diagnosis of lumbar disc herniation. Angiographic visualization of the epidural vein has been tried and investigated by intraosseus injection of contrast agent into lumbar spinous process and intravascular injection into iliac vein since first report in 1954. Recently, lumbar epidural venography is instituted by selective catheterization of ascending lumbar vein or internal iliac vein. Lumbar epidural venography is valuable for the diagnosis of herniated lumbar disc, not demonstrated by myelography. Especially, lumbar epidural venography is more accurate than myelography in the diagnosis of L5-Sl disc herniation and in the case of extreme lateral herniation. Other advantages of epidural venography are low incidence of complication and ease of performance. Epidural venography may be recommended as an alternative rnethod rather than as adjunctive to myelography. We report 20 cases of epidural venography, compared with myelographic and operative findings.

Various endoscopic techniques have been developed to overcome the difficulties in biliary or pancreatic access during endoscopic retrograde cholangiopancreatography, according to the preference of the endoscopist or the aim of the procedures. In terms of endoscopic methods, guidewire-assisted cannulation is a commonly used and well-known initial cannulation technique, or an alternative in cases of difficult cannulation. In addition, precut sphincterotomy encompasses a range of available rescue techniques, including conventional precut, precut fistulotomy, transpancreatic septotomy, and precut after insertion of pancreatic stent or pancreatic duct guidewire-guided septal precut. We present a literature review of guidewire-assisted cannulation as a primary endoscopic method and the precut technique for the facilitation of selective biliary access.
