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.

PURPOSE: Effective literature searching is essential to support evidence-based nursing. The aim of this study was to present our recent systematic search experience to identify guidelines in PubMed for prevention of catheter-associated urinary tract infections. METHODS: Five approaches to the literature search via PubMed were employed. The searches were restricted to items published from 1980 to 2010, for patients admitted to hospital, and in the English language. The search results were compared using the number of records and relevant items, and the sensitivity and precision of each search strategy. RESULTS: The individual approaches retrieved 19-141 of records and 3-6 of relevant items. Sensitivity ranged from 37.5% to 75.0% with the highest values for simple searches and a search combining MeSH terms and free textwords with a methodological search filter. Precision varied from 4.3% to 21.7% and the highest precision was found for MeSH terms with limits feature. CONCLUSION: The simple search in PubMed is an appropriate way for nurses in a busy clinical practice to search the literature for evidence. However, several approaches using MeSH terms, free textwords, limits feature or methodological search filters are also required to have more efficient and better informed search results.

4.Reconsideration of urine culture for the diagnosis of acute pyelonephritis in children: a new challenging method for diagnosing acute pyelonephritis
Korean Journal of Pediatrics 2019;62(12):433-437
Acute pyelonephritis (APN) should be detected and treated as soon as possible to reduce the risk of the development of acquired renal scarring. However, in the medical field, urine culture results are not available or considered when the prompt discrimination of APN is necessary and empirical treatment is started. Furthermore, urine culture cannot discriminate APN among children with febrile urinary tract infection (UTI) (pyelitis, lower UTI with other fever focus). Therefore, the usefulness of urine culture for diagnostic purposes is small and the sampling procedure is invasive. Congenital hypoplastic kidney is the most common cause of chronic kidney injury in children. Thus, it is desirable that a main target be detected as early as possible when imaging studies are performed in children with APN. However, if APN does not recur, no medical or surgical treatment or imaging studies would be needed because the acquired renal scar would not progress further. Therefore, the long-term prognosis of APN in young children, particularly infants, depends on the number of recurrent APN, not other febrile UTI. New methods that enable prompt, practical, and comfortable APN diagnosis in children are needed as alternatives to urinary catheterization for urine culture sampling.

OBJECTIVETo evaluate the effect of placement of urethral catheter combined with lidocaine on urethral irritation caused by postoperative indwelling catheters.
METHODSA total of 120 male surgical patients requiring postoperative indwelling catheters between June 2011 and January 2012 were divided into two equal groups for placement of painless urethral catheter combined with bladder washing with lidocaine on the first postoperative day, or for routine catheter placement only. The symptoms of urethral irritation such as urethral pain, urinary urgency, and perineal discomforts were observed and compared between the two groups.
RESULTSIn patients with painless urethral catheter placement combined with bladder washing with lidocaine, 11 developed urethral irritation symptoms, as compared to 24 in the patients with routine catheter placement only, showing a significant difference between the two groups (P<0.05).
CONCLUSIONPlacement of painless urethral catheter combined with bladder washing with lidocaine can significantly reduce the incidence of urethral irritation due to postoperative indwelling catheters.

PURPOSE: Urinary catheterization is a common technique in clinical practice. There is, however, no consensus on management prior to removal of the indwelling catheter for short-term patients. This systematic review examined the necessity of clamping before removal of an indwelling urinary catheter in short-term patients. METHODS: A systematic literature review was conducted using eight databases and predetermined keywords-guided searches. Some 2,515 studies were evaluated. Ten studies that met the inclusion criteria were selected. RESULTS: The quality of the studies was assessed using the Jadad scoring system. Only 40.0% of studies were rated as high quality. This review found that catheter clamping prior to removal was not necessary for the short-term patient. When made a comparison with the unclamping group, there was no significant difference in recatheterization risk, risk of urine retention, patients' subjective perceptions and rate of urinary tract infection. CONCLUSIONS: This review indicated that bladder training by clamping prior to removal of urinary catheters is not necessary in short-term catheter patients. In addition, clamping carries the risk of complications such as prolonging urinary catheter retention and urinary tract injury. Further investigation requires higher quality methodologies and more diverse study designs.

Nonvascular intervention of the urinary tract is a well-established uroradiologic subspecialty, which is more important for avoiding invasive open surgery in the age of rising demand about the value of less invasive treatment. Various kinds of nonvascular intervention are recently performed under image-guidance and are as follows: percutaneous nephrostomy, percutaneous nephrostolithotomy, percutaneous dilatation of the urinary tract, sclerotherapy for renal cysts, percutaneous catheter drainage, percutaneous foreign body retrieval and biopsy. Percutaneous nephrostomy is a basic technique to provide a direct access to urinary tract, which makes it possible to perform other interventional procedures. Although nonvascular intervention may produce some complications, it is generally considered to be less invasive than open surgery and has advantages such as short hospital stay, early return to normal life and therefore economic savings. This review is described to help clinicians easily understand the procedures, indications, techniques, and complications with figures of cases the authors experienced.

Foreign body (FB) ingestion of children is a common pediatric emergency requiring medical attention. Pediatric emergency physicians and gastroenterologists often encounter nervous and distressed situations, because of children presenting with this condition in the common clinical practice. When determining the appropriate timing and indications for intervention, physicians should consider multiple patient- and FB-related factors. The utilization of a flexible endoscopy is considered safe and effective to use in these cases, with a high success rate, for the effective extraction of FBs from the gastrointestinal tract of a child. Additionally, a Foley catheter and a magnet-attached Levin tube have been used for decades in the case of FB removal. Although their use has decreased significantly in recent times, these instruments continue to be used for several indications. Using a Foley catheter for this purpose does not require special training and does not necessarily require sedation of the patient or fluoroscopy, which serve as advantages of utilizing this method for foreign object retrieval. An ingested magnet or iron-containing FB can be retrieved using a magnet-attached tube, and can be effective to retrieve an object from any section of the upper gastrointestinal tract that can be reached. Simple and inexpensive devices such as Foley catheters and magnet-attached tubes can be used in emergencies such as with the esophageal impaction of disk batteries if endoscopy cannot be performed immediately (e.g., in rural areas and/or in patients presenting at midnight in a facility, especially in those without access to endoscopes or emergency services, or in any situation that warrants urgent removal of a foreign object).

OBJECTIVETo investigate the effects of transurethral catheterization on the uroflow rate in the pressure-flow study of patients with benign prostatic hyperplasia (BPH).
METHODSThirty-nine men with BPH underwent free uroflowmetry and pressure-flow analysis respectively. With an 8 F urethral catheter, the standard pressure-flow variables such as the maximum flow rate, detrusor pressure at the maximum flow rate and so on were recorded. The free maximum flow rate and the maximum flow rate with transurethral catheterization were statistically analyzed.
RESULTSThe maximum voided volumes of the free uroflowmetry group and the pressure-flow study group were (209.23 +/- 56. 56) ml and (210.33 +/- 62.02) ml respectively (P > 0.05). The free maximum flow rate was (8.61 +/- 2.80) ml/s, and the maximum flow rate with transurethral catheterization-was (7.39 +/- 3.01) ml/s (P < 0.05). When the patients were divided into seven grades of bladder outlet obstruction (BOO) according to the Schäfer nomogram, the free maximum flow rate and the maximum flow rate with transurethral catheterization with Grade 0-I of BOO were (12.56 +/- 1.57) ml/s and (10.95 +/- 2.51) ml/s, and those of Grade II were (9.35 +/- 0.76) ml/s and (8.41 +/- 1.23) ml/s respectively. For Grades III, IV and V-VI , the two maximum flow rates were (7.88 +/- 1.21) ml/s and (6.37 +/- 0.59) ml/s, (6.54 +/- 1.93) ml/s and (5.55 +/- 2.48) ml/s, and (6.01 +/- 2.10) ml/s and (4.84 +/- 2.89) ml/s, respectively, all with significant difference in between (P < 0.05).
CONCLUSIONThe 8 F urethral catheter has a significant effect on the maximum uroflow rate in the pressure-flow study and this effect is correlated with the grade of BOO.

PURPOSE: We retrospectively evaluated the efficacy of botulinum neurotoxin A (BoNT-A) on vesicoureteral reflux (VUR), continence status, and urodynamic parameters in children with myelodysplasia who were not responsive to standard conservative therapy.METHODS: The study included 31 children (13 boys, 18 girls) with a mean age of 9.2±2.3 years (range, 5–14 years) with myelodysplasia, retrospectively. All children were fully compatible with clean intermittent catheterization (CIC) and did not respond to the maximum tolerable anticholinergic dose. All children received an intradetrusor injection of 10 U/kg (maximum, 300 U) of BoNT-A into an infection-free bladder. All patients had VUR (22 unilateral, 9 bilateral) preoperatively. The grade of reflux was mild (grades 1, 2), intermediate (grade 3), and severe (grades 4, 5) in 25, 7, and 8 ureters, respectively.RESULTS: The mean maximum bladder capacity increased from 152.9±76.9 mL to 243.7±103 mL (P<0.001), and the maximum detrusor pressure decreased from 57±29.4 cm H₂O to 29.6±13.9 cm H₂O (P<0.001). After BoNT-A treatment, 16 refluxing ureters (40%) completely resolved, 17 (42.5%) improved, 5 (12.5%) remained unchanged, and 2 (5%) became worse. Of the 31 children with urinary leakage between CICs, 22 (71%) became completely dry, 6 (19%) improved, and 3 (10%) experienced partial improvement.CONCLUSIONS: In children with myelodysplasia, we were able to increase bladder capacity, enhance continence, and prevent VUR by using intradetrusor BoNT-A injections. Although our results are promising, a larger group of long-term prospective studies are warranted to investigate this method of treatment.
