fdg pet ct and renal scan demonstrations of carcinoma in the urinary Bladder and Bladder Diverticulum
Clinical Nuclear Medicine, 2013Co-Authors: Yiyan LiuAbstract:Bladder tumors arising within or involving a Bladder Diverticulum are uncommon, and pose a unique diagnostic and therapeutic challenge. A 58-year-old man with Bladder cancer diagnosed by cystoscopy had FDG PET/CT and 99mTc-MAG3 renal scan. The images demonstrated a large Bladder Diverticulum continuous from and within the tumor. Surgical pathology from transurethral partial resection of the Bladder Diverticulum showed high-grade carcinoma, mixed transitional with squamous cells invading into the muscularis propria.

urothelial carcinoma arising within Bladder Diverticulum report of a case and review of the literature
Urological Science, 2016Co-Authors: Hung-en Chen, Yi-chia Lin, Yi-hong ChengAbstract:Abstract Bladder Diverticulum is an outpouching of Bladder mucosa through the musculature of the Bladder wall. The incidence of Bladder Diverticulum in Taiwan is about 1.7% in children and 23.4% in adults. Intradiverticular carcinoma of urinary Bladder is uncommon. It ranges from 0.8% to 14.3%. Here we report a case of urothelial carcinoma within a Bladder Diverticulum. A 60-year-old male patient had history of BPH under medical treatment and right ureteral stone treated with extracorporeal shock wave lithotripsy (ESWL). He presented with painless gross hematuria about 3 months after ESWL. Intravenous pyelography showed a filling defect within the Bladder Diverticulum. Histopathological diagnosis of low grade urothelial carcinoma arising from the Bladder Diverticulum was made following cystoscopic biopsy. Laparoscopic partial cystectomy was performed with subsequent intravesical chemotherapy. Tumor recurrence was found not from the previous Diverticulum but from another area during regular cystoscopy at the 6-month postoperative follow up. He underwent transurethral resection of Bladder tumor. Pathology revealed a noninvasive, high grade urothelial carcinoma. There was no further Bladder tumor recurrence during the 1-year follow-up period. Bladder-sparing surgery with close cystoscopy follow up for intradiverticular urothelial carcinoma can be applied as an alternative treatment modality.

A case of ileus surgery using the water pressure method against ileus caused by incarceration into the inverted Bladder Diverticulum
Surgical Case Reports, 2020Co-Authors: Hirotsugu Morioka, Jun Aoki, Kazuyoshi Fujino, Yuki Sugahara, Michihiro Orihata, Michitoshi Goto, Shigeru Kobayashi, Yu OkazawaAbstract:Background Ileus is quite a common disease, but is associated with various causes. As far as we know, there have only been one case of ileus due to inverted Bladder Diverticulum, which is extremely rare. Case presentation The patient was a 53-year-old male. He made an emergency visit to our hospital with a chief complaint of left lower quadrant pain. He underwent right inguinal hernia surgery at 2 years of age with no history of laparotomy. An abdominal enhanced CT revealed inversion of the Bladder left side wall where part of enlarged small intestine was found. Ascites were also found between the incarcerated small intestine and the Bladder, leading to a diagnosis of strangulation ileus due to internal hernia and subsequent emergency surgery. A laparotomy revealed incarceration of the small intestine in the Bladder left wall as a Richter type. The incarceration was rigid. We believed it would be difficult to pull out by extraction. Therefore, we inserted a Nelaton catheter between the incarcerated small intestine and the Bladder and carried out the water pressure method to release the ileus. We did not perform an enterectomy since no manifest necrosis or perforation of the small intestine was found. The inverted Bladder wall was a partial depression. We interpreted it to be a Bladder Diverticulum. We made a suture for occlusion with the Bladder Diverticulum inverted. Ileus arising from inverted Bladder Diverticulum is a very rare disease state. We hereinafter report on this case along with bibliographical considerations. Conclusions We experienced a case of small intestine ileus due to inverted Bladder Diverticulum, which is very rare. In terms of preservation of the bowel, we believed the water pressure method to release the ileus was useful.

Urethral obstruction from dislodged Bladder Diverticulum stones: a case report
BMC Urology, 2012Co-Authors: Linus I Okeke, Augustine O Takure, Sikiru A Adebayo, Olukayode Y Oluyemi, Abimbola Aa OyelekanAbstract:Background Secondary urethral stone although rare, commonly arises from the kidneys, Bladder or are seen in patients with urethral stricture. These stones are either found in the posterior or anterior urethra and do result in acute urinary retention. We report urethral obstruction from dislodged Bladder Diverticulum stones. This to our knowledge is the first report from Nigeria and in English literature. Case presentation A 69 year old, male, Nigerian with clinical and radiological features of acute urinary retention, benign prostate enlargement and Bladder Diverticulum. He had a transurethral resection of the prostate (TURP) and was lost to follow up. He re-presented with retained urethral catheter of 4months duration. The catheter was removed but attempt at re-passing the catheter failed and a suprapubic cystostomy was performed. Clinical examination and plain radiograph of the penis confirmed anterior and posterior urethral stones. He had meatotomy and antegrade manual stone extraction with no urethra injury. Conclusions Urethral obstruction can result from inadequate treatment of patient with benign prostate enlargement and Bladder Diverticulum stones. Surgeons in resource limited environment should be conversant with transurethral resection of the prostate and cystolithotripsy or open prostatectomy and diverticulectomy.

Transurethral incision and fulguration of Bladder Diverticulum
Hinyokika kiyo. Acta urologica Japonica, 1991Co-Authors: Mutsushi Kawakita, Kamoto T, Tatsushiro OkabeAbstract:We treated 8 patients with Bladder diverticula transurethrally. All four quadrants of the diverticular neck which acts as a sphincter and traps residual urine in the Diverticulum was incised and the diverticular mucosa was fulgurated until the Diverticulum was effaced. The diverticula had markedly shrunk in 2 cases and had totally disappeared in 3. Followup was incomplete in 3 cases. We found that transurethral incision and fulguration of the Bladder Diverticulum, in combination with transurethral treatment for the Bladder outlet obstruction, is a safe, effective and less complicated method.
