A 14-year-old, spayed female, poodle was presented with dysuria and hematuria. A mass that appeared hypoechoic on ultrasound and hypoattenuating on computed tomography (CT) extended from the bladder neck to the urethra. Magnetic resonance imaging (MRI) showed the mass invading the muscular layer of the bladder, urethra, and prostate with distinct margins. Transitional cell carcinoma (TCC) was confirmed with the CADET-BRAF test. This study describes the CT and MRI features of suspected TCC lesions involving the bladder, prostate, and urethra. MRI showed superior soft tissue contrast resolution, enabling evaluation of invasion of the muscular layer of the bladder and urethra.

A giant prostatic urethral calculus has not been previously reported in dogs and should be distinguished from prostatic calculus. A 7-year-old castrated male Maltese dog with a 2-month history of relapsing hematuria and urinary incontinence with slowly progressing paraphimosis was referred. On abdominal radiography and ultrasonography, there was a giant calculus in the region of prostate or urethra, one left ureteral calculus, one urinary bladder calculus, and two penile urethral calculi. On computed tomography for evaluating the accurate location and planning the surgical approach, the giant calculus was located at the prostatic urethra. The calculi in urinary bladder, prostatic and penile urethra were surgically removed. These calculi were mixed-type of calcium oxalate monohydrate, struvite and calcium phosphate carbonate. On the basis of the urolith analysis and urine bacterial culture results, antibiotics and prescription diet were adjusted. At the 3-month follow-up, there were no clinical sings but paraphimosis was still remained, and ultrasonography revealed newly-formed, small urethral calculi at the prostatic urethra. This is the first report to describe the case of a canine giant prostatic urethral calculus and its clinical signs, diagnostic imaging findings, treatment, and outcome. CT may be useful to assess the accurate location and surgical approach for such calculi.

Extranodal lymphoma presents in almost one-third of all non-Hodgkin lymphoma cases. The gastrointestinal tract, skin, and central nervous system are common sites of involvement, whereas the urethra and cervix are very rare. To the best of our knowledge, this is the first report on concurrent extranodal involvement of the uterine cervix and urethra. We report imaging findings of malignant lymphoma involving urethra and cervix concurrently in a 79-year-old female patient with literature review. The magnetic resonance imaging showed huge intermediate to high signal intensity mass on T2 weighted images and strong homogeneous enhancement in uterine cervix and periurethral area, but no surrounding architectural disruption.

25마리의 다양한 종의 수컷 개에서 전립선에서 음경골까지 각 부위의 요도를 최대로 확장하여 측정 후 그 경향을 조사하였다. 전립선, 요도막, 협부, 회음부, 고환, 고환앞, 음경골 부위에 각각 풍선카테터를 위치한 후 풍선 내에 조영제를 주입하여 영상촬영 후 분석하였다. 협부를 제외하고 전립선에서부터 음경골로 갈수록 각 부위의 최대 확장된 직경은 점점 줄어들었다. 골반 부위 근처에 위치한 협부에서 카테터의 풍선을 전립선 부위와 회음부로 견인 시 25마리 중 22마리의 개에서 강한 저항감이 있었고 직경 또한 원위부와 근위부의 직경보다 더 작았다. 이러한 결과는 요도를 확장시켜 요도 내 결석을 제거하는 수압추진법의 적용 계획을 세우는 데 기여할 것으로 사료된다.

Hypospadias is a congenital malformation of the male genitalia. The reconstructive objectives are to obtain voiding with laminar flow and satisfactory sexual function. Several urethroplasty techniques have been described, but for perineal or revisional cases no single technique has shown robust success. In this study, we describe the expanded use of intestinal flaps for urethral reconstruction and report a peculiar request from a patient to undergo peno-urethral separation after successful hypospadias repair with a free ileum flap. A 51-year-old male patient with perineal hypospadias underwent several urethral reconstructive procedures with poor outcomes. A free ileum flap was attempted as a substitute for the urethra. Following successful reconstruction, separation of the neo-urethra (ileum) from the penile body was performed to address the patient's sexual expectations. A free ileum flap proved to be a reliable urethral substitute in perineal hypospadias reconstruction, with a successful outcome. The peno-urethral separation with the creation of an "accessory penis," however peculiar, optimized the results in terms of both sexual and urinary function. Anatomical restoration of the urethra and patient-reported expectations are the key to successful hypospadias reconstructive procedures. Sexual function outcomes and the patient's perception of success should not be underestimated, even when urinary function has been restored.

Purpose: The purpose of the study was to investigate traumatic urethral injury in a 63-year-old patient with hematuria. Methods: A hematuria patient was transferred by paramedics. At the time of the visit, the patient's blood pressure (151/91mmHg), pulse rate (86/min), body temperature (37.1℃), and other vital signs were stable. Their KTAS (Korean Triage and Acuity Scale) was Level 4. The patient had no damage to the injured area, but a large contrast defect was observed between the prostate urethra and the bladder in urethral angiography performed due to persistent hematuria and pain in the injured area. Results: Following radiological evaluation of a suspected liposarcoma or neuroma mass of the prostate urethra, the mass was removed through urethral tumor resection. The result of histologic evaluation provided a diagnosis of highly differentiated invasive urethral cell carcinoma that had invaded the muscle layer. The patient was given additional treatment for urethral cancer but was rejected and is currently being followed. Conclusion: The prognosis for urinary tract cancer has distinct differences for patients with lymph node metastasis and tumor characteristics. The presence or absence of urethral cancer should be confirmed through angiography, CT, MRI, and cystoscopy.

We introduce a convenient method of urethrography before catheterization for patients with pelvic trauma that can be used in a resuscitation area. A 10-mL syringe without a needle was used. X-ray contrast medium (Iohexol, 300 mg I/mL) was administered through the urethral orifice using a 10-mL syringe without needle and a simple pelvic anteroposterior film was taken (70 kilovolt [peak], 50 mAs). A 36-year-old soldier with a saddle injury from a gun barrel was taken to a trauma center. He had a pelvic fracture and complained of hematuria. Bedside urethrography above described was performed. The anterior urethra showed nonspecific findings, but dye leaked from the posterior urethra. Bedside Foley catheter insertion was attempted, but the catheter could not be advanced past the membranous urethra. Thereafter, suprapubic catheterization was performed. On the day of the injury, iliac artery embolization was carried out. The dislocated sacroiliac joint was also treated using open reduction and internal fixation. On hospital day 7, guidewire Foley insertion was performed. This bedside urethrography technique is simple and useful for pelvic fractures in which urethral injury is suspected.

Purpose: This research was conducted to study whether the specific location of pelvic-bone fractures could increase the risk for injury to the urinary bladder, urethra, or lower gastrointestinal tract. Methods: We retrospectively reviewed the data of 234 patients with pelvic-bone fractures who visited the emergency department of Kyungpook National University Hospital from January 2004 to December 2006. The location of the pelvic-bone fracture was divided into 8 parts. The association of fracture location with injury to the urinary bladder, urethra, or lower gastrointestinal tract was analyzed with Fisher' s-exact test and multiple logistic regression. Results: Nineteen(19) patients had urinary bladder injury, 8 had urethral injury, and 9 had lower gastrointestinal tract injury. The following fracture locations were found to be significant; urinary bladder: sacroiliac (SI) joint (p<0.001), symphysis pubis (p=0.011), and sacrum (p=0.005); urethra: SI joint (p=0.020); lower gastrointestinal tract: symphysis pubis (p=0.028). After the multiple logistic regression analysis, the primary and the independent predictors for each of the injuries were as follows; urinary bladder: sacroiliac joint (p=0.000, odds ratio [OR]=10.469); lower gastrointestinal tract: symphysis pubis (p=0.037, OR=7.009). Conclusion: Consideration of further workup for injuries to the lower gastrointestinal and urinary tract is needed for some locations of pelvic-bone fractures because certain pelvic-bone fracture locations, especially the sacroiliac joint and the symphysis pubis, are associated with increased risk for injury to the lower gastrointestinal and urinary tracts.
