Objective: To demonstrate the safety and efficacy of flexible ureteroscopy lithotripsy (FURL) and miniaturized percutaneous nephrolithotomy (MPCNL) through the comparative studies in treating medium-sized lower-pole renal calculi. Methods: Two hundred and twenty eligible patients with lower-pole renal calculi (1–2 cm) were enrolled and further randomly assigned into FURL group and MPCNL group. Patients' demographics, preoperative characteristics, intraoperative and postoperative complications, stone-free rate, and comfort and pain indicated by Bruggrmann Comfort Scale (BCS) and visual analog scale (VAS) were evaluated and recorded. Trauma index such as white blood cells, C-reactive protein (CRP), and interleukin (IL)-6 were also detected. Results: The stone-free rate and the operating time were comparable in FURL and MPCNL groups. Intraoperative and postoperative complication analysis showed that blood loss and hospital stay were significantly lower in the FURL group compared with MPCNL group. No significant difference in minor pelvic perforation, false passage, hemoglobin drop, persistent hematuria, ureteral perforation, moderate fever, urosepsis, and postoperative serum creatinine level was observed. However, as to comfort and pain indicated by BCS and VAS and stress indicated by CRP and IL-6, FURL was superior to MPCNL. Conclusion: FURL could be a better alternative surgical method to MPCNL with similar curative effect and less blood loss and hospital stay.

Background: The best choice of first-line treatment for metastatic hormone-sensitive prostate cancer (mHSPC) is unclear. We aimed to compare the effectiveness and safety determined in randomized clinical trials of doublet and triplet treatments for mHSPC.Methods: Medline, Embase, Cochrane Central and ClinicalTrials.gov were searched from inception through July 01, 2022. Eligible studies were phase III randomized clinical trials evaluating androgen deprivation treatment (ADT) alone, doublet therapies [ADT combined with docetaxel (DOC), novel hormonal agents (NHAs), or radiotherapy (RT)], or triplet therapies (NHA+DOC+ADT) as first-line treatments for mHSPC. Outcomes of interest included overall survival (OS), progression-free survival (PFS) and grades 3-5 adverse events (AEs). Subgroup analyses were performed based on tumor burden. The effects of competing treatments were assessed by Bayesian network meta-analysis using R software.Results: Ten trials with 12,298 patients comparing nine treatments were included. Darolutamide (DARO) +DOC+ADT ranked best in terms of OS benefits (OR 0·52 [95% CI 0·39–0·70]), but its advantages were all statistically insignificant compared with other therapy options except for DOC+ADT (OR 0·68 [95% CI 0·53–0·88]) and RT+ADT (OR 0·57 [95% CI 0·40–0·80]). In terms of PFS, enzalutamide(ENZA)+DOC+ADT (OR 0·32 [95% CI 0·24–0·44]) and abiraterone and prednisone (AAP) +DOC+ADT (OR 0·33 [95% CI 0·25–0·45]) ranked best. For patients with high volume disease (HVD), low volume disease (LVD), and visceral metastases, the optimal therapies were AAP+DOC+ADT (OR 0·52 [95% CI 0·33–0·83]), apalutamide+ADT (OR 0·52 [95% CI 0·26–1·05]) and DARO+DOC+ADT (OR 0·42 [95% CI 0·13–1·34]), respectively. For safety, AAP+DOC+ADT (OR 3·56 [95% CI 1·51–8·43]) ranked worst with the highest risk of grade 3−5 AEs.Conclusions: Triple therapies may further improve OS and PFS but may be associated with a decrease in safety. Triplet therapies could be suggested for HVD patients, while doublet combinations should still be preferred for LVD patients.Systematic Review Registration: https://www.crd.york.ac.uk/PROSPEROFILES/303117_STRATEGY_20220202.pdf, identifier CRD4202303117.

Fungus ball and fungal emphysematous cystitis are two rare complications of fungal urinary tract infection. A 53-year-old male patient presented with these complications caused by Candida tropicalis simultaneously. The predisposing factors were diabetes mellitus and usage of broad-spectrum antibiotics. The fungus ball, measuring 3.5 × 2.0 cm on the left wall of the urinary bladder, shrank significantly to 1.6 × 0.8 cm after 5 days of intermittent irrigation with saline before surgery. With transurethral removal of the fungus ball and antifungal treatment with fluconazole, the patient fully recovered. We conclude that a bladder fungus ball and fungal emphysematous cystitis should always be suspected in patients with diabetes mellitus with uncontrolled funguria and abnormal imaging. Treatment should include a systemic antifungal therapy and thorough surgical removal of the fungus ball. A systemic antifungal therapy combined with a local irrigation with saline or antifungal drugs might help decrease the dissemination of fungemia during an invasive manipulation.

Background: To report a new standardized cognitive fusion technique on transperineal targeted biopsy (TB) of prostate, and to evaluate its efficacy for cancer detection combined with systematic biopsy (SB) . Methods: We present a retrospective review of consecutive patients undergoing multiparametric magnetic resonance (mpMRI) imaging of the prostate with subsequent transperineal prostate biopsy from January 2016 to December 2018. A free-hand 12-core SB was performed for each patient. PI-RADS 3–5 lesions were further targeted for biopsy with our TB technique. Firstly, a central point of suspicious lesion (B′) was registered cognitively on a transverse section of transrectal ultrasound (TRUS). Then, biopsy gun punctured vertically through a fixed pioneer site (A) on skin of perineum, and deep into the TRUS section to get A’. Next, targeted site (B), the surface-projection of B′, would be determined on skin of perineum by A and distance from B′ to A’. Finally, puncture through B to reach B′. Pathological findings of SB and TB were analyzed. Results: A total of 126 patients underwent transperineal prostate biopsy (47 SB only, 79 SB + TB). The age of the patients was 68.7 ± 9.2 years. The median preoperative PSA value was 11.8 ng/mL. Preoperative prostate volume was 60.5 ± 50.0 mL. The numbers of patients with PI-RADS scores of 1 through 5 were 4, 43, 27, 21 and 31, respectively. The overall detection rate of cancer was 61/126 (48.4%), and it was significantly higher in the combination cohort (56/79, 70.9%) compared with the SB only cohort (5/47, 10.6%, p<0.001). When focused on the combination cohort, TB detected a similar overall rate of PCa (53/79, 67.1% vs 52/79, 65.8%; p = 0.87) compared with SB. The clinically significant PCa (csPC) detection rate was 52/79 (65.8%), while for TB and SB the csPC/PC rate was 51/53 (96.2%) and 48/52 (92.3%), respectively(p = 0.44). TB demonstrated a better sampling performance (positive rate for each core) compared with SB (51.0% vs 31.3%, p < 0.001). Conclusions: Surface-projection-based transperineal cognitive fusion targeted biopsy of the prostate has a good efficacy in detecting PCa.

Background: Bilateral adrenal hemorrhage (BAH) is a rare but potentially catastrophic condition. Its clinical manifestation is often non-specific and sometimes difficult to be diagnosed in time. Case summary: A 57-year-old woman, who presented with severe fatigue, nausea and vomiting after left hip arthroplasty due to her femoral neck fracture in a local hospital, was transferred to our medical center. Laboratory results revealed significant hyponatremia, low serum cortisol and elevated serum ACTH. Computed tomography (CT) showed a bilateral adrenal mass, measured 3.6 × 2.7 cm on the left and 3.4 × 2.3 cm on the right. Further magnetic resonance imaging (MRI) confirmed the diagnosis of BAH. The patient was prescribed with oral prednisolone acetate, 5 mg, tid, and her condition improved gradually. Nine months after, the patient was in good condition with 5 mg prednisolone acetate per day. CT revealed a clearly shrunken adrenal mass compared with 9 months ago. Conclusions: This case illustrates the difficulty in making the diagnosis of BAH with atypical presentation. Such cases necessitate greater alertness on the part of the clinician and require rapid diagnosis and prompt glucocorticoid replacement for better clinical outcomes.
