A 22-year-old woman met with road traffic accident 6 months back following which she underwent exploratory laparotomy with intraperitoneal bladder rupture repair. She presented with urethrovaginal fistula due to a fragment of fractured pubic bone impinging into the anterior vaginal wall. The findings were confirmed on CT scan and cystoscopy. The patient was managed with removal of the bony spicule and transvaginal repair of urethrovaginal fistula with Martius fat pad interposition.

Inflammatory pseudotumor is a rare benign condition of unknown cause. A 19-year-old female presented with gross hematuria and storage symptoms to the emergency. Contrast-enhanced computed tomography scan revealed a mass of 5 cm × 6 cm involving the dome and anterior wall of the bladder. Urachal carcinoma was kept as a possibility and transurethral biopsy of the aforementioned lesion was performed. The histopathology revealed inflammatory myofibroblastic tumor (IMT) of the bladder. A laparoscopic partial cystectomy was undertaken with adequate resection margins and the histopathology of the lesion confirmed IMT...

Uterine leiomyomas are the most common benign gynaecological tumours. However, 0.13 to 6% of them have malignant potential (Robboy et al. Environ Health Perspect 108(Suppl 5):779-784, 2000). Uterine smooth muscle tumours with unusual growth patterns include a spectrum of lesions such as intravenous leiomyomatosis, benign metastasizing leiomyoma and disseminated peritoneal leiomyomatosis (Vaquero et al. J Minim Invasive Gynecol 16:263-268, 2009). Benign metastasizing leiomyoma (BML) is a very rare condition with around 100 cases reported to date...

BACKGROUND: The brain's role in continence is critical but poorly understood. Although regions activated during bladder stimulation have been identified, little is known about the interaction between regions. In this secondary analysis we evaluate resting state and effective connectivity in older women treated for urgency urinary incontinence (UUI). METHOD: 54 women ≥60 years old with UUI and 10 continent women underwent fMRI scanning during provocation of urinary urgency, both before and after therapy...

A 66-year-old man was referred to our hospital after being diagnosed with a pelvic tumor. A subsequent transperineal biopsy revealed spindle cells with CD34·c-kit(+). An enhanced computed tomography scan showed a giant rectal-derived tumor in the pelvis. The tumor was pressing on the urinary bladder and the prostate, and appeared to invade the posterior wall ofthese organs. The patient was diagnosed with rectal GIST, and neoadjuvant therapy with 400mg/day imatinib was initiated. Three months later, the tumor reduction rate was at 33...

A 69-year-old obese man was involved in a high-speed head-on motor vehicle collision. He was tachycardic and normotensive on arrival. He subsequently developed hemodynamic instability requiring blood transfusion. On examination he had bilateral pneumothoraces, an anterior-posterior compression (APC) pelvic fracture, an open wound at the left groin, and gross hematuria after Foley catheter placement.CT imaging revealed hemoperitoneum, right hepatic lobe grade II lacerations, splenic laceration, mesenteric root injury with extravasated contrast, intraperitoneal and extraperitoneal bladder rupture, bilateral ureteral injuries at the level of the pelvic inlet (see figure 1), APC pelvic fracture, bilateral rib fractures, pneumothoraces, and pulmonary contusions...

PURPOSE: The purpose of the study is to determine the feasibility of using computed tomography-based texture analysis (CTTA) in differentiating between urothelial carcinomas (UC) of the bladder from micropapillary carcinomas (MPC) of the bladder. METHODS: Regions of interests (ROIs) of computerized tomography (CT) images of 33 MPCs and 33 UCs were manually segmented and saved. Custom MATLAB code was used to extract voxel information corresponding to the ROI. The segmented tumors were input to a pre-existing radiomics platform with a CTTA panel...

OBJECTIVE: 2-Fluorine-18-fluoro-2-deoxy-D-glucose positron emission tomography (18 F-FDG PET) imaging is not considered useful for assessing bladder cancer due to the physiological uptake of 18 F-FDG in the bladder. Despite reports of the detection of bladder cancer by washing out 18 F-FDG from the bladder, such methods are invasive and impractical in the routine practice. The purpose of this study was to evaluate prospectively the utility of oral hydration with 500 mL of water and voiding-refilling, a minimally invasive method that we introduced to enable detection of residual invasive bladder cancer on delayed 18 F-FDG PET imaging...

PURPOSE: Hypofractionated radiotherapy of prostate cancer is gaining clinical acceptance given its potential increase in therapeutic ratio and evidence for noninferiority and lack of added late toxicities compared to conventional fractionation. However, concerns have been raised that smaller number of fractions might lead to larger dosimetric influence by interfractional motion. We aim to compare the effect of these variations on hypofractionated pencil beam scanning (PBS) proton therapy and volumetric modulated arc therapy (VMAT) for localized prostate cancer...

BACKGROUND: Lesch-Nyhan syndrome is a rare inborn error of purine metabolism marked by a complete deficiency of the enzyme hypoxanthine-guanine phosphoribosyltransferase (HPRT). Inherited as an X-linked recessive genetic disorder that primarily affects males, patients with Lesch-Nyhan syndrome exhibit severe neurological impairments, including choreoathetosis, ballismus, cognitive dysfunction, and self-injurious behavior. Uric acid levels are usually abnormally high, leading to kidney and bladder stones which often necessitate urological intervention...

The pathophysiology of bladder leiomyosarcoma, a rare disease with aggressive mesenchymal tumor, is not certain, but its main symptoms are hematuria, dysuria and abdominal pain. Cases described in the literature are few. This report describes a case of a leiomyosarcoma of the urinary bladder in a 49-year-old woman. After CT scanning revealed a heterogeneously enhanced 4-cm mass involving the bladder neck and anterior wall, further examinations detected no metastatic lesion. Cystoscopy and transurethral resection of bladder tumor (TURBT) were performed...

Posterior urethral injuries typically arise in the context of a pelvic fracture. Retrograde urethrography is the preferred diagnostic test in trauma patients with pelvic fracture where a posterior urethral rupture is suspected. Pelvic fractures however preclude the adequate positioning of the patient on the X-ray table on admission and computed tomography scan with intravenous contrast and delayed films generally performed first. Suprapubic bladder catheter placement under ultrasound guidance should be performed whenever a posterior urethral disruption is suspected...

Background: Nephrogenic adenoma is a benign lesion found in the genitourinary tract, often at sites of prior inflammation, and is characterized by tubular, papillary, or tubulopapillary structures. It is thought to arise from distal migration and implantation of renal tubular cells into the renal pelvis, ureter, bladder, or urethra. These tumors often resemble malignant neoplasms. Morphologic variants include small tubules, signet ring-like pattern, papillary formations, flat pattern, and vessel-like structures...
