“…The US technique might also lead to misdiagnosis due to external factors, such as obesity and degree of bladder distension [20]. Despite the abovementioned pitfalls, since a skilled operator easily overcomes such difficulties, US still remains a useful diagnostic tool as it can greatly decrease the frequency of repeat cystoscopy for the follow-up of patients with nonmuscle invasive bladder carcinoma treated with TURBT [19,21].…”

Cystoscopy (CS) is considered to be the gold standard in the follow-up of non-muscle invasive bladder cancer. However, CS is invasive, time-consuming, and expensive. On the other hand, modern sensitive transducers have improved the imaging of urinary tract rendering transabdominal ultrasonography (US) more effective in visualizing intraluminal filling defects in the bladder than it was in the past. Twenty-five follow-up patients of low-risk bladder cancer meeting the inclusion and exclusion criteria were included in study. Ultrasonography of the bladder was performed by a single senior radiologist, and subsequently, these patients were subjected to flexible cystoscopy under local anesthesia. Pain score was calculated for each of the cystoscopies done. Findings of transabdominal ultrasound of the bladder were correlated and compared with those of cystoscopy. Subjects with US and/or CS findings suggestive of recurrence underwent transurethral resection of bladder tumor (TURBT) under general anesthesia and confirmation of the bladder carcinoma was achieved by the histopathological examination. Mean patient age was 60.56 years with range of 29 to 77 years. The sensitivity of modern ultrasonographic techniques was found to be 84.61% with specificity of 91.7% taking flexible cystoscopy as the gold standard for detection of recurrence. The accuracy of US was 88% with positive predictive value of 91.7% and negative predictive value of 84.61%. Technological evolution has improved the accuracy of ultrasonography in diagnosis of bladder carcinoma. It represents a valuable surveillance tool in selected sub group of low risk non-muscle invasive bladder cancer patients.

The studies were aimed at the evaluation of the usefulness of non-invasive diagnostic methods including inquiry, clinical examination, transabdominal ultrasonography, cytologic examination of the urinary sediment, determination of blood serum concentrations of certain neoplastic markers, and urinalysis for early detection of neoplasms of the urinary tract and male genitals; and at the determination of the sensitivity and specificity of percutaneous ultrasonography combined with cytologic examination of the urinary sediment for detection of neoplasms of the kidneys and urinary tract, particularly of the urinary bladder. Urological examinations were performed in 300 workers occupationally exposed to oil derivatives. Neoplasms of the urinary tract and male genitals were detected in 37 (12.3%) workers. Neoplasms of the urinary bladder were found most frequently. They were diagnosed by non-invasive methods in 14 (4.7%) and verified clinically and histologically in 11 (3.7%) persons. The results seem to indicate the usefulness of non-invasive diagnostic methods for urological screening studies among occupational populations with increased risk of neoplasms of the urinary system and male genitals. The high sensitivity (93%) and high positive predictive coefficient (0.90) for the combination of transabdominal ultrasonography and cytological examination of the urinary sediment for detection of urinary system neoplasms seem to be tokens of their high diagnostic value and clinical usefulness.
