Multidetector CT cystography for imaging colovesical fistulas and iatrogenic bladder leaks

Multidetector computed tomography (MDCT) cystography currently represents the modality of choice to image the urinary bladder in traumatized patients. In this review we present our experience with MDCT cystography applications outside the trauma setting, particularly for diagnosing bladder fistulas and leaks. A detailed explanation is provided concerning exam preparation, acquisition technique, image reconstruction and interpretation. Colovesical fistulas most commonly occur as a complication of sigmoid diverticular disease, and often remain occult after extensive diagnostic work-up including cystoscopy and contrast-enhanced CT. We consistently achieved accurate preoperative visualization of colovesical fistulas using MDCT cystography. Urinary leaks and injuries represent a non-negligible occurrence after pelvic surgery, particularly obstetric and gynaecological procedures: in our experience MDCT cystography is useful to investigate iatrogenic bladder leaks or fistulas. In our opinion, MDCT cystography should be recommended as the first line modality for direct visualization or otherwise confident exclusion of both spontaneous enterovesical fistulas and bladder injuries following instrumentation procedures, obstetric or surgical interventions

Cutaneous lesions of the external ear

Skin diseases on the external aspect of the ear are seen in a variety of medical disciplines. Dermatologists, othorhinolaryngologists, general practitioners, general and plastic surgeons are regularly consulted regarding cutaneous lesions on the ear

Cutaneous lesions of the nose

Skin diseases on the nose are seen in a variety of medical disciplines. Dermatologists, otorhinolaryngologists, general practitioners and general plastic and dermatologic surgeons are regularly consulted regarding cutaneous lesions on the nose. This article is the second part of a review series dealing with cutaneous lesions on the head and face, which are frequently seen in daily practice by a dermatologic surgeon. In this review, we focus on those skin diseases on the nose where surgery or laser therapy is considered a possible treatment option or that can be surgically evaluated

Iatrogenic Nonendoscopic Bladder Injuries Over 24 Years: 127 Cases at a Single Institution

OBJECTIVE To analyze the etiology, diagnosis, and long-term outcomes of iatrogenic nonendoscopic bladder injuries over a 24-year period. METHODS All iatrogenic bladder injuries were entered prospectively into our database from 1990 to 2014. Information gathered included causative procedure, injury characteristics, management, and outcome. RESULTS A total of 127 patients with nonendoscopic iatrogenic bladder injuries were included (111 women [87%], 16 men [13%]; mean age 51 years [range, 23-84]). Risk factors were identified in 92 patients (79%) including prior surgery, inflammation, and extensive tumor. Obstetric-gynecologic surgery accounted for most injuries (65%), with hysterectomy the most common procedure, followed by cesarean section. General surgery and nonendoscopic urologic injuries accounted for 22% and 13% respectively. Most injuries occurred during open surgery (77%) compared with vaginal (12%) and laparoscopic surgeries (11%). Laparoscopic surgery was associated with a delay in diagnosis, P = .002. Bladder injuries with concomitant ureteral injuries were more likely to have long-term complications, P = .001. CONCLUSION In analyzing iatrogenic bladder injuries at our institution over 24 years, we observed that hysterectomy and cesarean sections were the 2 most common causative procedures. A delay in diagnosis was more likely to occur during laparoscopic surgery. Complications occurred more commonly with a concomitant ureteral injury. (C) 2014 Elsevier Inc
