Various strains can be found in emphysematous prostatic abscesses (EPAs), but the most frequent causative organism is Klebsiella pneumoniae . Hypervirulent K. pneumoniae can disseminate to distant sites by forming a muco-polysaccharide network outside the capsule. Here, we present the first case of K. pneumoniae in an EPA accompanied by a spinal cord infarction. A 65-year-old man was referred to our hospital due to sudden-onset paraplegia after a 5-day history of fever, myalgia, and voiding difficulty. Abdominal computed tomography revealed a collection of air pockets in the prostate, and diffusion-weighted magnetic resonance imaging showed high signal intensity in the thoracic spinal cord. The patient was initially treated with antibiotics and surgical drainage. On the third hospital day, therapeutic heparin was added after discussion with a neurologist. The patient had no inflammatory symptoms, experienced some improvement in paraplegia, and was discharged on the 14th hospital day. This study adhered to the case report guidelines.

Background/Aims: Ursodeoxycholic acid (UDCA) is the only well-established and widely used agent for dissolving gallstones. Epidemiological and animal studies have suggested potential therapeutic benefits of n-3 polyunsaturated fatty acids (PUFA) for dissolving cholesterol gallstones. We evaluated whether adding PUFA to UDCA improves gallstone dissolution in patients with cholesterol gallstones. Methods: This randomized, prospective, preliminary clinical trial compared the efficacy and safety of UDCA plus PUFA combination therapy (combination group) with those of UDCA monotherapy (monotherapy group). The inclusion criteria were a gallstone diameter ≤15 mm on ultra-sonography, radiolucent stones on plain X-ray, and no to mild symptoms. Gallstone dissolution rates, response rates, and adverse events were evaluated. Results: Of the 59 screened patients, 45 patients completed treatment (24 and 21 in the monotherapy and combination groups, respectively). The gallstone dissolution rate tended to be higher in the combination group than in the monotherapy group (45.7% vs 9.9%, p=0.070). The radiological response rate was also significantly higher in the combination group (90.5% vs 41.7%, p=0.007). In both groups, dissolution and response rates were higher in patients with gallbladder sludge than in those with distinct stones. Four adverse events (two in each group) were observed, none of which were study drug-related or led to drug discontinuation. The incidence of these adverse events was similar in both groups (combination vs monotherapy: 9.5% vs 8.3%, p=0.890). Conclusions UDCA plus PUFA therapy dissolves cholesterol gallstones more effectively than UDCA monotherapy, without significant complications. Further prospective, large-scale studies of this combination therapy are warranted.

Purpose: This study aimed to assess the clinical outcome and safety of holmium laser enucleation of the prostate (HoLEP) following transrectal ultrasound-guided prostate biopsy (TR biopsy) in the treatment of benign prostate hyperplasia. Materials and Methods: We retrospectively analyzed data from 556 patients who underwent HoLEP between 2014 and 2021. The patients were categorized into six groups: Group 1-A (n=45) underwent HoLEP within four months post TR biopsy. Group 1-B (n=94) underwent HoLEP more than four months post TR biopsy. Group 1-C (n=120) underwent HoLEP after a single TR biopsy. Group 1-D (n=19) underwent HoLEP after two or more TR biopsies. Group 1-total (n=139, group 1-A+group 1-B or group 1-C+group 1-D) underwent HoLEP post TR biopsy. Group 2 (control group, n=417) underwent HoLEP without prior TR biopsy. We examined perioperative parameters, safety, and functional outcomes. Results: The age, body mass index, International Prostate Symptom Score (IPSS), uroflowmetry, and comorbid diseases between group 1-total and group 2 were comparable. However, group 1-total exhibited significantly elevated prostate-specific antigen levels and larger prostate volumes (p<0.01). Perioperative factors like enucleation time, enucleation weight, and catheterization duration were notably higher in group 1-total (p<0.01). All groups showed significant improvements in IPSS, postvoid residual urine, and maximum flow rate during the 1-year postoperative period (p<0.05). The rates of postoperative complications were similar between group 1-total and group 2. Conclusions Enucleation time and catheterization duration were significantly longer in the TR biopsy group. However, postoperative complications were not significantly different between TR biopsy and non-TR biopsy groups.

Purpose: To investigate the relationship between urine cytology results after overnight continuous saline irrigation (OCSI) following transurethral resection of bladder tumor (TURBT) and bladder tumor recurrence in non-muscle invasive bladder cancer (NMIBC). Materials and Methods: A retrospective study was conducted on patients diagnosed with NMIBC between 2016 and 2020 after undergoing TURBT at our hospital. All patients received OCSI following TURBT and had urine cytology test at postoperative 1 day.Urine cytology was classified into three groups: Negative, low-grade urothelial neoplasm (LGUN)+atypical urothelial cells (AUC), and suspicious for high-grade urothelial carcinoma (SHGUC)+high-grade urothelial carcinoma (HGUC). Recurrence-free survival (RFS) in each group was compared using the Kaplan–Meier method. Univariable and multivariable Cox regression analyses were performed to evaluate independent prognostic factors. Results: A total of 172 patients were included in this study. Based on urine cytology group (after OCSI), RFS did not reach the median value in the Negative group. In the LGUN+AUC group, the median RFS was 615.00 days. In the SHGUC+HGUC group, the median RFS was 377.00 days. In survival analysis, the Negative group had a longer RFS than the SHGUC+HGUC group (p=0.013).However, Cox regression analysis showed that SHGUC+HGUC was not an independent prognostic factor for recurrence. Conclusions Urine cytology results after OCSI following TURBT in NMIBC were associated with bladder tumor recurrence. Specifically, SHGUC or HGUC in urine cytology after OCSI showed earlier recurrence than negative cases. However, further research is needed to accurately determine whether it is an independent prognostic factor.
