RESUMO

PURPOSE: Cxbladder tests are urinary biomarker tests for detection of urothelial carcinoma. We developed enhanced Cxbladder tests that incorporate DNA analysis of 6 single nucleotide polymorphisms for the FGFR3 and TERT genes, in addition to the current 5 mRNA biomarkers and clinical risk factors. MATERIALS AND METHODS: Two multicenter, prospective studies were undertaken in: (1) U.S. patients with gross hematuria aged ≥18 years and (2) Singaporean patients with gross hematuria or microhematuria aged >21 years. All patients provided a midstream urine sample and underwent cystoscopy. Samples were retrospectively analyzed using enhanced Cxbladder-Triage (risk stratifies patients), enhanced Cxbladder-Detect (risk stratifies patients and detects positive patients), and the combination enhanced Cxbladder-Triage × Cxbladder-Detect. RESULTS: In the pooled cohort (N=804; gross hematuria: n=484, microhematuria: n=320), enhanced Cxbladder-Detect had a sensitivity of 97% (95% CI 89%-100%), specificity of 90% (95% CI 88%-92%), and negative predictive value of 99.7% (95% CI 99%-100%) for detection of urothelial carcinoma. Overall, 83% of patients were enhanced Cxbladder-Detect-negative (ie, needed no further work-up). Of 133 enhanced Cxbladder-Detect-positive patients, 59 had a confirmed tumor, of which 19 were low-grade noninvasive papillary carcinoma or papillary urothelial neoplasm of low malignant potential. In total, 40 tumors were high-grade Ta, T1-T4, Tis, including concomitant carcinoma in situ. Of the 74 patients with normal cystoscopy, 41 were positive by single nucleotide polymorphism analysis. Enhanced Cxbladder-Triage and enhanced Cxbladder-Detect had significantly better specificity than the first-generation Cxbladder tests (P < .001). CONCLUSIONS: This study in ethnically diverse patients with hematuria showed the analytical validity of the enhanced Cxbladder tests.

RESUMO

Objective The objective of this study was to evaluate the efficacy and long-term outcomes of the use of Restorelle® Direct Fix (Coloplast, Humlebæk, Denmark) anterior mesh for transvaginal surgical management of anterior compartment prolapse. Methods A retrospective case series review was conducted for 123 patients who underwent surgery for Baden-Walker Grade three and four anterior compartment prolapse with the Restorelle Direct Fix anterior mesh between July 1, 2017 and September 30, 2018 in a single center. Follow-up was conducted at one, six, 12, 24, and 36 months after treatment. A standardized questionnaire and pelvic examination were conducted at each visit to assess operative complications and subjective and objective cure rates. Results Sixty patients were included in the analysis with a three-year follow-up rate of 70.0%. At three years post-operatively, subjective and objective cure rates were 97.7% and 95.3% respectively. Seven (11.7%) patients complained of de novo stress urinary incontinence, four (6.7%) complained of de novo urge urinary incontinence and one (1.7%) complained of symptomatic recurrence. Significantly, six (10.0%) patients had transvaginal mesh exposure over the three-year follow-up, mostly presenting within the first year. One (2.4%) patient developed new asymptomatic mesh erosion at the 36-month visit and one patient required mesh loosening one month post-surgery. Conclusions Management of anterior compartment prolapse with transvaginal surgery using the Restorelle® Direct Fix anterior mesh was associated with good subjective and objective cure rates. However, significant rates of post-operative mesh exposure were noted within three years post-surgery, which hinders the recommendation of this device for augmentation of repair for anterior compartment prolapse.

RESUMO

A colovaginal fistula (CVF) is an abnormal epithelialized connection between the colon and the vagina. It is a rare complication following gynaecology surgery and can significantly affect patients' quality of life. CVFs are commonly associated with diverticular disease and are usually seen in patients with a previous hysterectomy. We report an uncommon case of postsurgical CVF following vaginal hysterectomy with mesh-augmented pelvic floor repair, which was unrelated to diverticulitis. The patient was successfully managed by a multidisciplinary team with staged surgery.

RESUMO

Adrenal gland tumours in pregnancy are very rare occurrences and have highly variable clinical presentations. The timely diagnosis of adrenal tumours in pregnancy is extremely important, as failure to do so may lead to fatality. As there is limited published literature on adrenal tumours in pregnancy and no consensus on its management, the management of such patients with regard to medical and surgical treatments, as well as timing of delivery, must therefore be individualised and carried out with multidisciplinary expertise. We present two cases of adrenal tumours in pregnancy, both with favourable outcomes and variable gestations. Our first and second cases discuss a large phaeochromocytoma and a cortisol-secreting adrenal cortical adenoma in pregnancy, respectively.
