Endoscopic Cystolithotripsy for a Giant Stone in The Orthotopic Neobladder: A Case Report
Radical cystectomy and urinary diversion is an excellent treatment option for invasive bladder cancer. Ileal conduit and orthotopic neobladder have been applied as the most frequent urinary diversion methods for many years. Stone formation is a rare complication in the ortotopic neobladder. In the case presented, a 67-year-old-man who had undergone radical cystectomy and orthotopic neobladder reconstruction ten years ago with no complaints in the following five years presented with fever, dysuria, and urinary frequency. We detected a 10.8 cm stone in the neobladder, and the giant stone was fragmented by endoscopic cystolithotripsy via transurethral approach. Complete stone clearance was achieved
Cutaneous Metastasis from Squamous Cell Carcinoma of The Bladder: A Case
Objective: To report a case with cutaneous metastasis of bladder squamous cell carcinoma. Very few cases of skin metastases from the urinary bladder are reported in the literature.Case report: Cutaneous metastasis of bladder squamous cell carcinoma is an extremely rare clinic entity associated with poor prognosis. Cutaneous metastasis is accepted as a late manifestation of systemic spread. A 58-year-old man had undergone radical cystoprostatectomy with pelvic lymph node dissection in November 2013. The pathology report showed a moderately differentiated squamous cell bladder carcinoma with a staging of T3N0M0. Then, a large regional cutaneous lesion measuring 4x3.5 cm with an ulcerated and necrotic appearance located in the suprapubic area was detected in February 2014, and the lesion was removed with a 2 cm safety margin. The pathologic examination revealed squamous cell carcinoma. This report describes an interesting and rare case of cutaneous metastasis of bladder squamous cell carcinoma as the primary presentation of metastatic disease with a generally dismal prognosis.Conclusion: The skin metastasis of bladder squamous cell carcinoma is a rare clinical entity with a poor prognosis. Clinicians should be aware of this rare entity

Association between blood lipid profile and urolithiasis: A systematic review and meta-analysis of observational studies
The objective of this study was to pool individual studies regarding the association of blood lipid profiles with urolithiasis to carry out a systematic review and meta-analysis. We searched MEDLINE, PubMed, Embase and Cochrane Library to identify the relevant studies up to November 2017. Studies that met all inclusion criteria were chosen, and a pooled analysis of the odds ratio between urolithiasis and dyslipidemia traits was calculated. A total of 11 observational studies (seven cross-sectional, three cohort, one case-control) with a total of 282 479 participants were examined. The overall pooled analysis of eight studies showed that high triglyceride was associated with increased estimated risk of urolithiasis (odds ratio 1.287, 95% CI 1.073-1.544; P = 0.007). Estimates of the total effect size were consistent in the sensitivity analysis. No evidence of publication bias was detected. The overall pooled analysis of nine studies showed low high-density lipoprotein was weakly associated with increased estimated risk of urolithiasis (odds ratio 1.171, 95% CI 1.010-1.358; P = 0.032). The sensitivity analysis showed conflicting results. No evidence of publication bias was detected. Three studies on the association between any dyslipidemia traits and urolithiasis showed a significant association (odds ratio 1.309, 95% CI 1.202-1.425; P < 0.001). The present meta-analysis showed that patients with higher triglyceride and lower high-density lipoprotein had an increased estimated risk of urolithiasis. A triglyceride-urolithiasis association was found to be more coherent and consistent compared with the high-density lipoprotein-urolithiasis association. Although somewhat contradictory results have been found, the meta-analysis is encouraging for evaluating urolithiasis as a systemic disorder. Further well-designed prospective randomized controlled or cohort studies are necessary to better elucidate the causal association of dyslipidemia and urolithiasis
