Surgicel® granuloma mimicking ovarian cancer: A case report.

Surgicel® is an absorbable sterile mesh composed of oxidized cellulose that is used to control intraoperative capillary or venous bleeding, due to its capacity to bind hemoglobin, thus allowing the formation of an artificial clot. In the present study, a large granuloma mimicking ovarian cancer, which developed following placement of a Surgicel® sponge during a combined pubovaginal sling procedure and cystocele repair, is reported. The aim of the present case report is to emphasize the fact that hemostatic measures should be removed following their use, and to alert surgeons to the risk of using and leaving in situ oxidized cellulose. Furthermore, accurate evaluation of the surgical history of the patient should always be performed prior to attempting surgery.

Prognostic Factors for Anastomotic Urinary Leakage Following Retropubic Radical Prostatectomy and Correlation With Voiding Outcomes.

This study aimed to determine the occurrence and grade of cystographically detected urinary leakage (UL) in a contemporary series of open retropubic radical prostatectomy (RP), whether patients' clinical variables predict occurrence of UL, and whether occurrence of UL correlates with patients' voiding outcomes in terms of urinary continence and anastomotic stricture (AS). Enrolled patients underwent cystography 7 days after retropubic RP; in case of UL, the catheter was left in situ and cystography repeated at 7 days intervals until demonstrating absence of UL. Leakage was classified as grade I = extraperitoneal leak <6 cm, grade II = extraperitoneal leak >6 cm, grade III = leak freely extending in the small pelvis. Voiding was evaluated at 3, 6, and 12 months after RP using the 24-hour pad test and uroflowmetry; in cases of maximum flow rate <10 mL/s, urethrocystoscopy was carried out to determine presence and location of an AS. The first postoperative cystogram showed UL in 52.6% of patients (grade I in 48.1%, grade II in 21.5%, and grade III in 30.4% of the cases). Multivariate analysis demonstrated that patients with UL had significantly greater prostate volume (64.5 vs 34.8 cc, P < 0.001), loss of serum hemoglobin (4.77 vs 4.19 g/dL, P < 0.001), lower postoperative serum total proteins (4.85 vs 5.4 g/dL, P < 0.001), and higher rate of AS (20.6% vs. 2.8%, p < 0.001) than those without UL. Continence rate at 3, 6, and 12 months postoperatively was 34.2%, 76%, and 90%, respectively, in patients with UL compared with 77.5%, 80.3%, and 93% in patients without UL; such difference was statistically significant (P < 0.001) only at 3 months follow-up. ROC curve analysis showed that prostate volume and postoperative serum total proteins had the best AUC (0.821 and 0.822, respectively) and when combined, their positive and negative predictive values for UL were 90% and 93%, respectively. In conclusion, half of the patients undergoing open retropubic RP may present, 7 days postoperatively, some degree of cystographically detected UL; prostate volume, loss of serum hemoglobin, and postoperative serum total proteins could be used to predict it. UL delayed return to urinary continence without affecting long-term results, but led to a significantly higher rate of AS.

Magnetic resonance imaging of penile paraffinoma: case report.

BACKGROUND: Penile paraffinoma is a well-known delayed complication of paraffin oil injection into the penis for penile girth augmentation but its MRI features have not been previously described. CASE PRESENTATION: A 35-year-old Ukraine man presented with erectile dysfunction, voiding difficulty and an irregular, hard and painful penile mass that had progressively grown over the last year. He reported having received, seven years before, several penile injections of paraffin oil for penile girth augmentation. On physical examination, the mass was tender, poorly delimited, and involved the whole penile shaft and the cranial part of the scrotum. Preoperative MRI, performed to determine the extent of tissue to be removed and the possibilities of penile reconstruction, showed a newly-formed homogeneous tissue, compressing but not infiltrating Buck's fascia, iso-hypointense relative to muscle on T1-weighted sequences, and with a low signal intensity at T2-weighted sequences. On T1-weighted fat suppressed sequences, it did not enhance with contrast administration. MRI data were confirmed by surgical findings, as the newly-formed scar tissue did not infiltrate Buck's fascia. Pathology confirmed the diagnosis of penile paraffinoma. CONCLUSION: MRI seems to provide an adequate imaging of the histological events occurring after injection of paraffin oil in the subcutaneous tissues. Penile paraffinoma remains a clinical diagnosis, but MRI features may be helpful in planning an adequate surgical strategy and, in selected cases, establishing the differential diagnosis with other penile diseases, including cancer.
