Is Preoperative Pyuria Associated with Postoperative Febrile Complication after Ureteroscopic Ureter or Renal Stone Removal?: Seungsoo Lee; Urogenit Tract Infect 2020;15(1):1-5. Published online April 30, 2020; DOI: https://doi.org/10.14777/uti.2020.15.1.1

Abstract PDF PubReader ePub: Purpose: The association between preoperative pyuria and postoperative febrile complications after ureteroscopic ureter or renal stone removal was examined.
Materials and Methods: From June 2014 to July 2016, 110 patients who underwent ureteroscopic ureter or renal stone removal by a single surgeon were evaluated. The patients were categorized as the “pyuria group” and “nonpyuria group.” The sex, age, stone laterality, stone location, stone size, preoperative urine culture results, and postoperative complications in each group were analyzed.
Results: The pyuria and nonpyuria groups were comprised of 55 patients each. The mean ages the pyuria and nonpyuria groups were 58.4±16.1 years and 54.4±13.2 years, respectively. There were respectively, 43 and 12 unilateral and bilateral stones in the pyuria group, and 53 and two in the nonpyuria group. The stone sizes of the pyuria and nonpyuria groups were 13.1±5.4 mm and 11.1±4.7 mm, respectively. The pyuria group contained more patients with bilateral stones and larger stones than the nonpyuria group. Five and two postoperative febrile complications were encountered in the pyuria group and the nonpyuria group, respectively. No significant difference in febrile complications was observed between the two groups. In logistic regression analysis, bilateral stones and larger stones were associated with pyuria.
Conclusions: In ureteroscopic stone removal surgery, preoperative pyuria was associated with bilateral and larger stones, but there were no associations with febrile complications.

Case of Fournier’s Gangrene in a Patient with Long-Term Indwelling Catheterization due to Urinary Incontinence after Open Radical Prostatectomy: Kyung Kgi Park, Sung Dae Kim, Young-Joo Kim, Jung-Sik Huh; Urogenit Tract Infect 2020;15(1):6-9. Published online April 30, 2020; DOI: https://doi.org/10.14777/uti.2020.15.1.6

Abstract PDF PubReader ePub: Fournier’s gangrene is a life-threatening disease that needs to be treated as soon as possible. An 82-year-old male, who exchanged a urethral catheter once a month for urinary incontinence management after open radical prostatectomy, presented with an acute onset of mental change and general weakness. After ten days’ hospitalization, the disease was diagnosed. The scrotal wall was opened, and the infectious tissue was exposed to the air and kept open with an aseptic dressing. After 45 days, his scrotal wound healed and returned to its typical appearance without scarring and wound disruption. He recovered fully from the infection. This paper reports a case of Fournier’s gangrene in a patient with long-term indwelling catheterization due to urinary incontinence after an open radical prostatectomy with a literature review.

Penile Strangulation: A Novel Surgical Procedure without Cutting Equipment: Young Gon Kim, Yu Seob Shin, Jae Hyung You; Urogenit Tract Infect 2020;15(1):10-12. Published online April 30, 2020; DOI: https://doi.org/10.14777/uti.2020.15.1.10

Abstract PDF PubReader ePub: Strangulation of the penis is a rare condition that usually results from the placement of various constricting devices to enhance sexual stimulation. Such a condition requires emergency treatment to prevent penile ischemia, necrosis, urethral injury, and erectile dysfunction. This paper reports the case of a 51-year-old man who was referred for penile pain and swelling following the self-placement of an industrial metallic ring at the base of the penis. The metallic ring was removed safely without using specialized equipment.

Von Brunn’s Nest in an Incidental Bladder Mass Found during Holmium Laser Enucleation of the Prostate: Seungsoo Lee; Urogenit Tract Infect 2020;15(1):13-15. Published online April 30, 2020; DOI: https://doi.org/10.14777/uti.2020.15.1.13

Abstract PDF PubReader ePub: A 62-year-old male with benign prostatic hyperplasia underwent holmium laser enucleation of the prostate. During surgery, a small nodular mass was found incidentally in the trigone of the bladder. The lesion was removed completely by a transurethral resection with a bipolar device. A pathology examination of the lesion indicated von Brunn’s nests.

Korean Translation of the GRADE Series Published in the BMJ, ‘GRADE: Grading Quality of Evidence and Strength of Recommendations for Diagnostic Tests and Strategies’ (A Secondary Publication): Jae Hung Jung, Do Kyung Kim, Ho Won Kang, Ja Yoon Ku, Hyun Jin Jung, Hong Wook Kim, Eu Chang Hwang, Guideline Development Committee in the Korean Association of Urogenital Tract Infection and Inflammation; Urogenit Tract Infect 2020;15(1):16-25. Published online April 30, 2020; DOI: https://doi.org/10.14777/uti.2020.15.1.16

Abstract PDF Supplementary Material PubReader ePub: This article is the fourth translation of a GRADE series published in the BMJ, which graded the quality of evidence and strength of recommendations for diagnostic tests or strategies, as a comprehensive and transparent approach for developing recommendations. Randomized trials for diagnostic approaches represent the ideal study design for intervention studies. On the other hand, cross-sectional or cohort studies with a direct comparison of the test results with an appropriate reference standard can provide high-quality evidence. The guideline panel must be reminded that the test accuracy is a surrogate for patient-important outcomes, so such studies often provide a low quality of evidence for recommendations regarding diagnostic tests, even when the studies do not have serious limitations. Diagnostic accuracy studies showing that a diagnostic test or strategy improves important patient outcomes will require the availability of effective treatment, reduction of test-related adverse effects or anxiety, or improvement of the patients’ well-being from prognostic information. Therefore, it is important to assess the directness of the test results regarding the consequences of diagnostic recommendations that are important to patients.
