  • Background: The purpose of this study was to investigate whether postoperative cystography findings can predict early and longterm recovery from incontinence after radical prostatectomy (RP), compared with the other cystography parameters. Methods: I retrospectively reviewed 118 patients who underwent robot-assisted RP (RARP) for localized prostate cancer at single institution between January 2016 and April 2021. One hundred and seven patients were included in the study. Postoperative cystography was routinely performed 7 days after surgery. The bladder neck to pubic symphysis ratio, vesicourethral angle, and bladder neck anteroposterior length (BNAP) ratio (the bladder neck-posterior margin distances divided by the anteroposterior lengths) were evaluated. Continence was defined as cessation of pad use. The association between these variables and urinary incontinence was also analyzed. Results: The urinary incontinence recovery rates 1, 3, 6, and 12 months after RARP were 43.92%, 66.35%, 87.85%, and 97.19%, respectively. Multivariate logistic regression analysis demonstrated that a lower BNAP ratio and wider vesicourethral angle were significantly associated with continence restoration at 1, 3, and 6 months after surgery. In addition, in terms of days of pad usage, lower BNAP ratio, wider vesicourethral angle, and bladder neck preservation were significantly associated with recovery from urinary incontinence within 12 months as assessed by Cox proportional hazard analysis. Conclusion: This study demonstrated that vesicourethral angle and BNAP ratio were independent predictors of early recovery from post-prostatectomy incontinence. I suggest that both the sagittal and coronal views of postoperative cystography help anticipate early continence restoration after RARP.

  • A 13-year-old, male Maltese was refered to Veterinary Teaching Hospital of Konkuk University with inappropriate urination and hematuria. CBC, serum chemistry profile, urinalysis and urine culture were performed. Malignant cells were found in the urine sediment. Thoracic and abdominal radiography, retrograde positive-contrast cystography, retrograde double-contrast cystography, excretory urography, ultrasonography were performed. On the retrograde positive-contrast cystography examination, irregular filling defects were present on the left side of the cranial part of the bladder. Partial cystectomy performed and then medical therapy was conducted. On histopathological examinations, the lesion was confirmed as a transitional cell carcinoma of the urinary bladder.

  • An intact male, 3-month-old, Great Pyrenees mountain dog, weighing 7.3 kg with a history of severe hematuria during 2 months was referred. Hematology showed mild leukocytosis. There were no remarkable findings in abdominal radiographs due to ingesta and gas in the gastrointestinal tracts. Ultrasonographs showed bilateral hydronephrosis, bilateral dilated and tortuous ureters, and hyperechoic sludges in the urinary bladder (UB). And a dilated cavity was identified cranial to the UB. Excretory urography and cystography were performed to examine the cause of hydronephrosis and an abnormal cavity cranial to the UB. Bilateral ureters were tortuously dilated and opened into the craniodorsal part of the UB. An abnormal cavity was connected to the UB at the left cranioventral part of the UB. Therefore bilateral ectopic ureters and urachal remnant were diagnosed.

  • Background: This study was performed to investigate the association between cystographic anastomotic urinary leakage (UL) after retropubic radical prostatectomy (RRP) and early urinary incontinence (UI). Methods: The medical records of 53 patients who had undergone cystography after RRP at our institution between January 2015 and December 2018 were retrospectively analyzed. Cystography was performed 7 to 10 days after surgery. The duration of catheterization depended on the degree of UL, which was classified as mild, moderate, or severe. The study subjects were divided into the non-UL group and the UL group. Continence was defined as the use of no pads. The prostate was dissected in an antegrade fashion, and urethrovesical anastomosis was performed with a continuous suture. Results: Incontinence rates at 1 and 3 months postoperatively were significantly higher in the UL group than the non-UL group (83.3% vs. 52.2%, p=0.014 and 76.7% vs. 47.8%, p=0.030, respectively); however, those at 6 and 12 months were not significantly different (23.3% vs. 17.4%, p=0.597 and 4.3% vs. 10.0%, p=0.440, respectively). The severity of UL was not found to influence the duration of incontinence. The presence of cystographic anastomotic UL was found to be predictive of UI during the first 3 postoperative months (odds ratio, 3.3; p=0.045). Conclusion: The presence of anastomotic UL on cystography was associated with higher rates of UI in the early postoperative periods. However, incontinence rates in patients with or without anastomotic UL immediately after RRP equalized at 6 months and the severity of UL did not affect the duration of postoperative UI.

  • To investigate diagnostic imaging of cystitis and to apply it to the small animal practice, ultrasonogram of urinary bladder with moderate distension(4ml/kg) and with complete distension(9ml/kg) to evaluate the irregularity and thickness of bladder, radiography and histopathological examination were performed after experimental cystitis induction. On double contrast cystography, mucosal membrane of the urinary bladder was smooth and thickening urinary bladder wall was not found before cystitis induction. At 3rd day post induction(PI), mucosal irregularity was noted at the cranioventral region of the urinary bladder. Thickening of the urinary bladder wall and filling defect was observed as well. Cystographic findings of 7, 10, 15, 21 day PI were similar to that of 3rd day PI. On ultrasonographic findings of the mural thickness in induction group, it was ascertain that the mural thickness with moderate distention was more thickened than with complete distention at transverse scan. Ultrasonographic findings at longitudinal scan were similar to those of transverse scan. On ultrasonographic findings of mucosal irregularity in induction group, from PI to 7 day PI, mucosal irregularity with moderate distention was more irregular than mucosal irregularity with complete distention. At 10 day PI, there was similarity between moderate distention and complete distention. On histopathologic examination of a section of urinary bladder taken 3 day PI, the mucosal and submucosa were infiltrated by a mixture of thick inflammatory exudate which was composed of neutrophil, plasma protein, bacterial colony and necrotic cells. Congestion, hemorrhage and edema were also observed in the submucosa. At 7th day PI, the mucosal change was similar to that of 3rd day PI, but neovascularization and fibroplasia were observed in the submucosa. At 15th and 21th day PI, mild hyperplasia of mucosal epithelium was observed in the mucosa. Deposition of collagen, neovascularization and severe diffuse infiltration of lymphocyte were observed. These results suggest that ultrasonographic examination with moderate distention is considered to be a more simple, rapid, noninvasive, sensitive and useful diagnostic method than other diagnostic methods for the diagnosis of the cystitis and the differential diagnosis of urinary tract infection.

  • Voiding cystourethrography (VCUG) is a commonly performed diagnostic procedure for the evaluation of vesicoureteral reflux with urinary tract infection or congenital renal diseases in children. The procedure is relatively simple and cost-effective, and complications are very rare. The iatrogenic complication of VCUG range from discomfort, urinary tract infection to bacteremia, as well as bladder rupture. Bladder rupture is a rare complication of VCUG, and only a few cases were reported. Bladder rupture among healthy children during VCUG is an especially uncommon event. Bladder rupture associated with VCUG is usually more common in chronically unused bladders like chronic renal failure. Presented is a case of bladder rupture that occurred during a VCUG in a healthy 9-month-old infant, due to instilled action of dye by high pressure. This injury completely healed after 7 days of operation, and it was confirmed with a postoperative cystography. The patient's bladder volume, underlying disease, velocity of the contrast media instilled, catheter size, and styles of instillation are important factors to prevent bladder rupture during VCUG. Management of bladder rupture should be individualized, but the majority of infants are treated with the operation. In conclusion, bladder rupture is a rare complication, however, delicate attention is needed in order to prevent more dire situations.
