Abstract

Adrenal myelolipomas are rare, hormonally silent, adipose and myeloid-containing lesions that are mostly asymptomatic. If they do present it is usually with mass-related flank pain or spontaneous haemorrhage. A 55-year-old female presented with right flank pain after a fall from a static pushbike. Computer tomography identified a large adrenal lesion with surrounding acute retroperitoneal haemorrhage. A conservative approach to treatment was decided on as the patient remained haemodynamically stable. The patient developed a pulmonary embolism during the time of conservative management and therefore had to be anticoagulated with close monitoring. Outpatient surveillance imaging was reassuring, hormonal screening was negative and biopsy confirmed myelolipoma. We report a rare presentation of adrenal myelolipoma with the sequelae of haemorrhage from low-impact trauma and the challenges of conservative management.

Abstract

Introduction: Many patients with non-muscle invasive bladder cancer (NMIBC) will develop recurrences of their tumour after their first resection. Flexible cystoscopy under local anaesthesia with Holmium-YAG laser ablation of tumour (FHoLAT) is safe, well tolerated procedure with significant cost savings when compared to cystoscopy under general or regional anaesthesia. We retrospectively analysed the outcomes of a large series of patients undergoing FHoLAT at our institution between April 2006 and September 2013. Patients and methods: Patients were offered FHoLAT if the tumour recurrence was small and/or they were deemed unfit for regional or general anaesthesia. Patient data was extracted from medical records. The primary outcomes were overall survival (OS), cancer-specific survival (CSS), progression-free survival (PFS) and recurrence-free survival (RFS). Results: 232 patients with a total 522 FHoLAT procedures were included. The median follow-up was 74.8 (43.5–101) months; 18% were discharged after a recurrence free follow-up duration; 52.2% had one FHoLAT, 19.8% had two FHoLATs, 11.2% had three FHoLATs and 16.8% had four or more FHoLAT. At initial diagnosis 24.1% of patients had G1pTa, 47% G2pTa, 9.9% G3pTa and T1 in 18.9%. 4.3% had concurrent carcinoma in situ. At 10 years, OS was 47.4%, CSS was 94.1%, PFS was 82.1%, RFS was 15.8%. Conclusions: FHoLAT for bladder tumour recurrences has an acceptable CSS and PFS for patients with small low-grade tumours or patients with high-grade or T1 tumours who are unfit for regional or general anaesthesia. The role of FHoLAT in unfit patients seems clear, but further prospective trials are needed to define its role in other patient groups, particularly high-grade NMIBC. Level of evidence: 3b-4

Abstract

Background: Patient factors associated with urinary tract cancer can be used to risk stratify patients referred with haematuria, prioritising those with a higher risk of cancer for prompt investigation. Objective: To develop a prediction model for urinary tract cancer in patients referred with haematuria. Design, setting, and participants: A prospective observational study was conducted in 10 282 patients from 110 hospitals across 26 countries, aged ≥16 yr and referred to secondary care with haematuria. Patients with a known or previous urological malignancy were excluded. Outcome measurements and statistical analysis: The primary outcomes were the presence or absence of urinary tract cancer (bladder cancer, upper tract urothelial cancer [UTUC], and renal cancer). Mixed-effect multivariable logistic regression was performed with site and country as random effects and clinically important patient-level candidate predictors, chosen a priori, as fixed effects. Predictors were selected primarily using clinical reasoning, in addition to backward stepwise selection. Calibration and discrimination were calculated, and bootstrap validation was performed to calculate optimism. Results and limitations: The unadjusted prevalence was 17.2% (n = 1763) for bladder cancer, 1.20% (n = 123) for UTUC, and 1.00% (n = 103) for renal cancer. The final model included predictors of increased risk (visible haematuria, age, smoking history, male sex, and family history) and reduced risk (previous haematuria investigations, urinary tract infection, dysuria/suprapubic pain, anticoagulation, catheter use, and previous pelvic radiotherapy). The area under the receiver operating characteristic curve of the final model was 0.86 (95% confidence interval 0.85-0.87). The model is limited to patients without previous urological malignancy. Conclusions: This cancer prediction model is the first to consider established and novel urinary tract cancer diagnostic markers. It can be used in secondary care for risk stratifying patients and aid the clinician's decision-making process in prioritising patients for investigation. Patient summary: We have developed a tool that uses a person's characteristics to determine the risk of cancer if that person develops blood in the urine (haematuria). This can be used to help prioritise patients for further investigation.

Abstract

Intestinal metaplasia (IM) of the bladder is an extremely rare benign condition. The clinical features are similar to other bladder tumours. Its pathogenesis is unclear and its role as a precursor of adenocarcinoma has long been debated. Transurethral resection is the main form of treatment for IM. We report the case of a 49-year-old gentleman who presented with visible haematuria. He was submitted to multiple cystoscopies which showed no macroscopic irregularities. Radiological (CT urogram and multiparametric MRI) imaging revealed abnormalities within the bladder neck, suspicious of a neoplastic lesion. Following transurethral resection of his trigonal area, pathology demonstrated IM occurring on a background of cystitis glandularis. This case highlights the unusual difficulty in macroscopically diagnosing IM of the bladder compared to other neoplasms of the bladder. Therefore, in patients with persistent visible haematuria there should be a low threshold to perform biopsies.

Abstract

To establish whether the regular biopsy of red patches (RPs) seen during endoscopic surveillance for bladder cancer is worthwhile and determine a suitable time frame for repeat biopsy of prior histologically benign persistent RPs in patients on endoscopic surveillance for bladder cancer.Four thousand eight hundred five flexible cystoscopy (FC) reports over a 12-month period were retrospectively reviewed at a United Kingdom tertiary teaching hospital and those undergoing cystoscopic surveillance for bladder cancer and found to have solitary RPs at FC were included in the study. A proportion of these cases had biopsies taken for histopathologic analysis.Two hundred forty-one FC performed on 183 patients on endoscopic surveillance for bladder cancer had RPs and 120 (49.8%) of them had previous intravesical Bacillus Calmette-Guerin therapy. Eighty-five patients (35.3%) underwent biopsy of the RP. Malignancy was found in 20 biopsies (23.5%), of which, 11 out of 20 (55%) were carcinoma in-situ. Sixteen of these recurrences were biopsied previously, of which 11 (68.8%) were benign at last biopsy, 6 of which were in the last 12 months. The remaining four recurrences had no previous biopsy. No cases of malignancy were identified in patients with low-risk bladder cancer.We recommend the biopsy of all RPs found during endoscopic surveillance of patients with intermediate-/high-risk bladder cancer due to the significant incidence of malignant recurrence identified, particularly if no biopsy has been performed within the previous 12 months. This is independent of previous biopsy histology.

Abstract

The introduction of laparoscopic nephroureterectomy highlights the need for the critical appraisal of approaches to the distal ureter at surgery for upper tract transitional cell carcinoma. We compared differences after endoscopic ureteral detachment and open bladder cuff excision in nephroureterectomy.A total of 138 patients underwent open nephroureterectomy for upper urinary tract transitional cell carcinoma from 1982 to 2005 with a median followup of 43 months. Of these patients 90 underwent endoscopic ureteral detachment and 48 underwent bladder cuff excision. Demographic, perioperative and oncological outcome data were collected in all cases. Statistical analyses were performed using the Student t test, chi-square and log rank tests, and logistic and Cox regression.Mean operative duration was significantly lower in the endoscopic detachment group than in the bladder cuff group (p0.01). There were 49 (54.4%) bladder recurrences in the endoscopic detachment group, of which 8 (16.3%) were muscle invasive and 3 (3.3%) developed at the resection site. There were 23 (47.9%) bladder recurrences in the bladder cuff group, of which 3 (13.0%) were muscle invasive and 2 (4.2%) developed at the resection site. All 5 resection site tumors occurred after excision of muscle invasive distal ureteral tumors and 4 of these had positive margins. There were no differences in recurrence-free survival or disease specific survival between the groups. Operation subtype did not predict oncological outcome on univariate or multivariate analysis.Endoscopic ureteral detachment reduces operative duration and is associated with equivalent oncological outcomes compared with open bladder cuff excision in nephroureterectomy. Caution should be exercised in patients with low ureteral tumors.
