Ultrasonic Aspiration System

The gold standard of surgical treatment for superficial bladder tumor is transurethral resection (TUR). However, the procedure has drawbacks: it needs skill to avoid perforation of the bladder wall, while burns on the resected tissue are disadvantageous for histological examination. We developed an endoscopic ultrasonic aspiration system which is easy to manipulate and makes no burns on aspirated tissue. Furthermore, the equipment includes a coagulating system.Transurethral ultrasonic aspiration was performed in 19 cases of superficial bladder tumor with a prototype 24Fr Y-shaped rigid endoscope. The efficacy of bladder tumor aspiration was evaluated and ultrasonic aspiration was compared to the conventional TUR procedure. Bladder tumors less than 2 cm were aspirated very rapidly. Blood loss was minimal and the largest tumor aspirated in this series weighed 6.5 grams. Aspirated tissue was large enough for histological examination. Compared to conventional TUR, the ultrasonic aspiration has advantages of no burns on aspirated tissue and easy manipulation. Transurethral ultrasonic aspiration may be an alternative procedure for the treatment of superficial bladder tumor.

Aim. In this study we report our experience with microhematuria and its relation with bladder tumors in Iranian women.Materials and Methods. Overall 249 women were evaluated. Microscopic hematuria was defined as three or more red blood cells per high-power field on at least two different occasions. Patients with a history of gross hematuria or coagulation disorders, having organic diseases, urinary stones, urinary tract infections, nephrological diseases, and local lesions such as urethral caruncle were excluded from the study population. Final diagnosis of malignant tumors was done with cystoscopy and biopsy specimen pathological assessment in all cases.Results. Age for the study population was49.7±11.8years. 95 (38%) of patients were identified during routine check up and presenting symptoms in other patients were frequency, dysuria, stress urge incontinence, urge incontinence, feeling of incomplete urine emptying, and flunk pain, respectively. Finally, 7 (2.8%) of study subjects were confirmed as having bladder tumors. One of tumor cases was diagnosed 24 months after initial assessments. Patients with bladder tumor were significantly older; more frequently had diverticulum in their bladder wall (P<.05).Conclusion. Female microscopic hematuria is relevant and deserves evaluations, especially in elderly patients. Patients whose reason for microhematuria would not be diagnosed at the initial evaluations should be followed.

The authors report their results in adjuvant immunotherapy with B.C.G. after TUR for superficial and multicentric bladder tumors (Ta-T1). After TURB a cycle of intravesical immunotheraphy with 150 mg of BCG (Bacillus Calmette-Guerin) is performed once a week for 6 weeks, ther every 2 weeks for 6 times and finally once a month for 1 year. (16.5 months of treatment). Controls with CTM and cystoscopy are performed periodically. 63 patients have been treated: 20 (60.6%) are free from disease with follow-up of 18–36 months; 87.5% of patients who had BCG as immunotherapy after first TUR for bladder tumor, are free from disease. Comparing their results with experiences reported in literature with Mytomicin and Doxorubicin, the authors think that adjuvant immunotherapy with BCG is actually the best local treatment for these tumors. Some patients (25%) had slight troubles because of therapy but only in 3 cases (9.09%) treatment was stopped. In conclusion intravesical therapy with BCG significantly changes natural history of superficial bladder tumor, increasing the time free from disease (in our experience: 27 months).

Introduction: The majority of diverticular bladder tumors (DBT) are urothelial. Due to the lack of the muscular layer in the diverticulum, the progression of these tumors is easier than in the bladder wall. Case report: The case of invasive DBT with painless hematuria is presented. The patient was treated with diverticulectomy. Conclusion: Unifocal Stage-T3 DBTs can be successfully treated with diverticulectomy.

Objective: The aim of the study was to compare the endoscopic versus percutaneous approach (blind) to control the obturator jerk in patients undergoing transurethral resection of bladder tumors under spinal anesthesia. Materials and methods: A prospective observational study was performed in Department of Urology, Chittagong Medical College, Chittagong and some Private Hospitals (Ltd.) in Chittagong city during the period from January 2016 to June 2016. Total 100 patients were grouped into two, on alternate basis. Fifty(50) patients in group- A conducted with endoscopic infiltration with 20ml of injection 2% lignocaine at the bladder tumor base and another 50 patients in group-B, conducted with blind percutaneous technique with same drug and volume ( 20ml inj.2% lignocaine) to control obturator jerk. Severity of obturator jerk in both procedure, percentage of complete resection, ONB procedure related time, ONB procedure related complications and surgeon’s satisfaction level were recorded and compared between two approaches. Chi-square analysis was performed to compare the ease of approach and outcome of the two techniques. A value of P<0.05 was considered statistically significant. Results: The mean age of the patients were 59.44+7.681. In group-A, 50 patients were given inj. 2% lignocaine endoscopically at the bladder tumor base to control obturator jerk. Twenty five patients (50%) had no jerk, 20 patients(40%) developed mild jerk and 5 patients (10%) developed moderate jerk and no patients developed severe jerk. Second attempt was taken in moderate jerk patients (5 patients) and succeeded in 3(6%) patients. So, in this group, complete resection of bladder tumor was possible in 96%. In group B, complete resection of bladder tumor was possible in 84%. Statistical analysis was done and result is significant in case of endoscopic procedure to control obturator jerk(p<0.05). ONB Procedure related time was <20 mins. in 32(64%) patients in group-A and 45 (90%) patients in group- B. 20 mins. or more time was required for 18 (36%) patients in group-A and 5 (10%) patients in group-B. Statistical analysis was done and result is significant in percutaneous (blind) technique (p<0.05). ONB procedure related complications in group-A and Group –B were noted. Statistical analysis was done and result is insignificant (p>0.05). Surgeons satisfaction level were recorded on the basis of obturator jerk block and complete resection and which was statistically significant in favour of endoscopy group (p<0.05). Conclusion: It is concluded that endoscopic injection of 2% lignocaine into the bladder tumor base is better in case of jerk elimination and complete resection than blind percutaneous approach. Though, ONB procedure related time was significantly less in percutaneous group. Bangladesh Journal of Urology, Vol. 21, No. 2, July 2018 p.120-126

Background: Bladder cancer is one of the most frequent type of urinary cancer which has been ever increasing. For the better treatment, the early discovery and definite diagnosis of this disease played an important role. Objective: To describe some clinical symptoms and ultrasound features of tumorlike lesions of the bladder. To diagnose and classify the histopathology of tumorlike lesions of the bladder. Materials, method: cross - sectional study on 64 cases in Hue University Hospital and Hue central hospital from April, 2016 to February, 2017. Results: Hematuria was the most common reason that patients went to hospital (79.7%). Lower abdominal pain and irritation during urination accounting for 9.4% and 6.2% respectively. Only 3 patients with bladder cancer were accidentally discovered through periodic health examination (4.7%). The characteristics of hematuria in bladder tumor was flesh red urine (62.5%) and total hematuria (60.7%). With ultrasonography, the results of 64 patients were divided in 3 groups as follow: bladder tumor, which was the highest rate 87.5%, bladder polyp was 3.1% and focal bladder wall thickening was 9.4%. Of which, the vast majority of these ultrasound images was tumor - like lesions protruding in the lumen of the bladder (75%), the rest was wall thickening lesions (25%). Tumors were different in size, the biggest tumor was 7cm in diameter and the smallest was 0.6cm. Those with the diameter 3cm or bigger accounting for 42.2%, the smaller was 57.8%. Most cases have only one lesion (62.5%) and at lateral wall (46.6%). Histopathologically, cancer was 59/64 case (92.2%): urothelial carcinoma was 98.3 %, squamous cell carcinomawas 1.7% and 5 cases (7.8%) were benign. Most cancerous cases were poorly differentiated, grade II (50.9%) and grade III (32.2%). The stage T1NxMx was 20.3% and worse than T2MxNx was 79.7%. Conclusion: hematuria was the most popular symptom, suggesting bladder cancer. Clinical diagnosing bladder cancer was not high sensitive (61.01%). Ultrasound could detect bladder tumor with high sensitive (89.8%). These patients also needed histopathology classification to diagnose and finally choose the best method for the appropriate treatment.

The aim of this study was to explore the possibility of using rabbit bladder as a model for experimental detrusor electrostimulation research. In a study of urinary bladder activity induced through electrostimulation of the ventral roots, the functional and morphological parameters of the rabbit detrusor were investigated. Under general anaesthesia, open electrostimulation of ventral spinal roots leading towards the detrusor (usually S<sub>2, </sub>S<sub>3</sub>) was performed in 20 rabbits. Detrusor response was recorded by repeated electromyography and cystometry in two groups: animals with naturally concentrated urine content (Group A, eight rabbits) and animals after flushing and filling the bladder with saline (Group B, 12 rabbits). Histological examination of bladder wall was performed in both groups. The measured values were compared to one another as well as with data from the veterinary and human literature. The histological specimens were compared with histological specimens of human bladder. The reaction of detrusor fibres was detectable by electromyography in all cases. Elevation of intravesical pressure as a consequence of detrusor contraction was more difficult to detect, as this depends more on the density of the intravesical content. The pressure rise in Group B had a higher amplitude &ndash; up to 15 cm H<sub>2</sub>O versus 5 cm H<sub>2</sub>O in the first group (P = 0.00046). Histological examination of bladder wall from the two groups of rabbits showed no differences. In comparison with the bladder wall in humans, the only differences found were significantly thinner detrusor layers relative to the overall thickness of bladder wall. It is possible to use rabbit bladder for research into experimentally electrostimulation-induced activity of the detrusor or for experimental detrusor reinnervation research. It is necessary, however, to take into account certain limits &ndash; the lower contractility of the bladder wall and the need for qualitative control of bladder content. The present results also suggest that the physiological micturition of rabbits is probably more dependent on abdominal pressure than in humans. &nbsp;

Myofibroblastic tumor, also known as inflammatory pseudotumor or pseudosarcoma, is a benign tumor with mesenchymal origin. Bladder location is very uncommon. We report the case of a 58-year-old man with a history of von Recklinghausen's disease who complained for painless macroscopic hematuria 5 months after suprapubic prostatectomy. The radiograph evaluation revealed a bladder tumor, and the pathologic examination following a transurethral resection showed inflammatory myofibroblastic tumor of the bladder. The patient finally underwent a radical cystectomy due to the uncertain pathogenesis of inflammatory myofibroblastic tumor as well as the rarity of cases published on bladder tumors in Von Recklinghausen's patients.
