Algorithm-based multidisciplinary treatment approach for rectourethral fistula.

PURPOSE: The purpose of this study is to report the outcomes of an algorithm-based multidisciplinary treatment approach to rectourethral fistula. METHODS: This study is a retrospective review of a prospectively collected database at a tertiary center of all consecutive patients treated between 2003 and 2013. RESULTS: Thirty males (mean age 63 years) were reviewed. Prostate cancer treatment was the most common fistula etiology (97%). Urinary drainage consisted of urethral catheter in all patients and suprapubic catheter in 14 (47%). The rate of fecal diversion was 67%. During a mean follow-up of 72 months, healing rate was 90% and recurrence rate 0%. Spontaneous healing was achieved in 14 patients (47%): 8 (27%) without fecal diversion and 6 (20%) following fecal diversion. Thirteen patients (43%) required definitive intervention. The majority of operated patients underwent transanal or transperineal flap (endorectal, dartos, or gracilis) successfully. Only 2 patients (7%) required an abdominal approach (positive oncologic margins or non-functioning bladder). Fifteen out of the 20 patients (75%) who underwent fecal diversion had stoma closure with an overall permanent stoma rate of 17%. Long-term urinary incontinence was noted in 11 patients (37%). Six patients (20%) required permanent urinary diversion or drainage catheters. CONCLUSIONS: Algorithm-based treatment approach for rectourethral fistula is useful in the management of this rare condition. Selective fecal diversion is possible, and majority of patients who require definitive intervention can be treated with a transanal or transperineal approach. The rate of permanent stoma is low, but long-term urinary dysfunction is frequent.

Management of rectal injuries sustained during laparoscopic radical prostatectomy.

OBJECTIVES: To report on a treatment algorithm for the management of rectal injures. Rectal injuries during laparoscopic radical prostatectomy (LRP) are rare. In the first 200 cases of LRP performed at our institution, 2 (1%) rectal injuries occurred. Our experience prompted collaboration with our colorectal surgery colleagues to develop a treatment algorithm for the management of such injuries. METHODS: We report on the management of rectal injuries sustained during LRP at our institution. We describe the intraoperative laparoscopic repair of a rectal tear using a 2-layer interrupted closure with absorbable suture. The conservative, nonoperative, management of a rectourethral fistula in a patient who presented after LRP is also described. Collaboration with our colorectal surgery colleagues resulted in the formulation of a treatment algorithm for intraoperative and postoperative presentations of rectal injury during LRP. The algorithm is presented. RESULTS: Of the first 200 cases of LRP at our institution 2 (1%) were complicated by rectal injury. Injuries recognized intraoperatively should be managed laparoscopically if the operating surgeon is adept at intracorporeal suturing. Small rectourethral fistulas can be managed conservatively with urinary catheterization or diversion and antibiotics as needed. Rarely, rectal injuries sustained during LRP will require fecal diversion; injuries that fail to heal despite fecal diversion require operative repair. CONCLUSIONS: Rectal injuries incurred during LRP are rare but must be managed successfully to minimize morbidity. Rectal tears recognized intraoperatively can be managed laparoscopically. The development of a rectourethral fistula is a potential complication of LRP. Most fistulas can be managed conservatively with urinary catheterization or diversion. Rarely, rectal injuries that occur during LRP require fecal diversion or definitive operative repair.

Review of the surgical approaches for Peyronie's disease: corporeal plication and plaque incision with grafting.

The understanding and management of Peyronie's disease (PD) has improved but elucidating the exact etiology of the disease has yet to be achieved. In this paper, we review the historical and clinical aspects of PD. We focus on the evolution of surgical management for PD and review recent published articles that compare popular surgical techniques such as plication and plaque incision with vein graft. These two techniques have been reported to be equivalent with respect to patient satisfaction; however, each technique has its own advantages and disadvantages.

Penile corporeal reconstruction during difficult placement of a penile prosthesis.

For some patients with impotence and concomitant severe tunical/corporeal tissue fibrosis, insertion of a penile prosthesis is the only option to restore erectile function. Closing the tunica over an inflatable penile prosthesis in these patients can be challenging. We review our previous study which included 15 patients with severe corporeal or tunical fibrosis who underwent corporeal reconstruction with autologous rectus fascia to allow placement of an inflatable penile prosthesis. At a mean follow-up of 18 months (range 12 to 64), all patients had a prosthesis that was functioning properly without evidence of separation, herniation, or erosion of the graft. Sexual activity resumed at a mean time of 9 weeks (range 8 to 10). There were no adverse events related to the graft or its harvest. Use of rectus fascia graft for coverage of a tunical defect during a difficult penile prosthesis placement is surgically feasible, safe, and efficacious.

IL-6 does not predict current urolithiasis in stone formers.

INTRODUCTION: Interleukin-6 (IL-6), an inflammatory marker, has previously been found to be elevated in the urine of patients with urolithiasis. Oxalate and other stone precursors have been shown to increase IL-6 production in proximal tubular epithelial cells in vitro. We examined whether urinary IL-6 could be used as a screening test to determine current urolithiasis in individuals who are known to form urinary stones. METHODS: Thirty-five adult patients with current urolithiasis demonstrated on imaging were enrolled in the study. Exclusion criteria included disease known to elevate IL-6. Each patient provided a pre-treatment urine specimen and one month after proven to be stone-free an additional urine specimen was obtained. The urinary IL-6/creatinine ratio was determined for both specimens and compared. RESULTS: Ten patients provided both specimens. The mean pre-operative urinary IL-6/creatinine ratio before the procedure was 1.63 pg/mL. The mean post procedure urinary IL-6/creatinine ratio after the patient was confirmed to be stone-free was 1.81 pg/mL. These were not significantly different (p=0.38). Preoperative urinary IL-6/creatinine ratio did not correlate to stone size (r=0.15) and no correlation was seen between time from treatment and stone free IL-6/creatinine ratio (r=0.48). CONCLUSION: Urinary IL-6 is not a good screening test for current urolithiasis in stone-forming individuals. It is elevated whether the stone is present or not.

Combined endorectal advancement flap with Alloderm graft repair of radiation and cryoablation-induced rectourethral fistula.

Rectourethral fistula is a potentially devastating disease for the patient and difficult management problem for the physician. We report a case of radiation and salvage cryoablation-induced rectourethral fistula for treatment of prostate cancer successfully repaired with a combined endorectal advancement flap with Alloderm graft. The surgical technique is described in detail. The patient is now one year post-repair with no evidence of recurrence.

Subjective patient-reported experiences after surgery for Peyronie's disease: corporeal plication versus plaque incision with vein graft.

OBJECTIVES: To compare patient-perceived outcomes of corporeal plication to plaque incision with saphenous vein grafting for the correction of Peyronie's disease. METHODS: Patients with stable Peyronie's disease deemed to be good operative candidates for both tunical plication and plaque incision with saphenous vein graft were counseled on both procedures and chose which operation they would undergo. At 1 year, the records were reviewed and the patients were contacted. The variables included age, operative time, and outcome ("satisfactorily straight," loss of rigidity, loss of sensation, new use of erectile aids, ability to have intercourse, palpable nodules, erectile pain, penile shortening, and being "completely satisfied"). RESULTS: Of the 67 patients, 35 underwent tunical plication and 32 underwent plaque incision with vein grafting. No differences were present in patient age between the two groups. The average operative time was shorter for the plication group (P = 0.0001). No differences were found regarding satisfactory straightness (P = 0.13), satisfaction with the operation (P = 0.71), new use of erectile aids (P = 0.06), erectile pain (P = 0.12), or subjective penile shortening (P = 0.41). Patients who underwent plaque incision with grafting were more likely to experience loss of rigidity (P = 0.03), inability to have intercourse (P = 0.05), and loss of sensation (P = 0.0045). Patients who underwent plication were more likely to experience palpable nodules (P = 0.03). CONCLUSIONS: The results of our study have shown that both procedures are effective surgical options for the correction of Peyronie's disease. Plication is a simple procedure with less morbidity. Shortening is a common complaint, regardless of the type of operation done.

Persistent mullerian duct syndrome and transverse testicular ectopia: embryology, presentation, and management.

BACKGROUND: The finding of persistent mullerian duct syndrome (PMDS) with transverse testicular ectopia (TTE) is rare. We present nonidentical triplets with PMDS with TTE. CASES: Triplet A presented with a right inguinal hernia and left nonpalpable testis at 4 months of age. Ultrasound demonstrated 1 testis in the right hemiscrotum. Laparoscopy revealed both testes in the right inguinal canal with a thick midline structure. Triplet B presented at 6 months of age in the exact manner with similar intraoperative findings as triplet A. No additional mullerian structures were identified in triplets A and B. Both underwent laparoscopic left orchiopexy and open right inguinal herniorraphy/orchiopexy. A portion of vas was noted in the path specimen of triplet B. Triplet C presented at 7 months of age with a nonpalpable left testis. Laparoscopy demonstrated bilateral fallopian tubes and a midline uterine remnant. Open bilateral orchiopexy was performed, and bilateral biopsies confirmed testes. All 3 were 46-X,Y. CONCLUSION: Persistent mullerian duct syndrome with TTE may be encountered when performing laparoscopy for patients with nonpalpable testis. The persistent mullerian remnants vary among individuals and alter the normal anatomy, thus may complicate diagnosis and surgical management.

Prognosis of seminal vesicle involvement by transitional cell carcinoma of the bladder.

PURPOSE: Transitional cell carcinoma (TCC) of the bladder that extends directly into contiguous organs (pT4) portends a poor prognosis. The 2002 American Joint Committee on Cancer staging system does not include seminal vesicle involvement by primary TCC of the bladder. In this analysis we evaluated the clinical outcomes and prognostic significance of seminal vesicle involvement with TCC of the bladder after radical cystectomy. MATERIALS AND METHODS: From 1971 to 2001, 1,682 patients underwent radical cystectomy and pelvic lymphadenectomy for bladder cancer. Only those tumors that involved adjacent organs through the bladder wall (pT4) were included. Overall 132 male patients with a median age of 68 years (range 36 to 98) qualified for analysis. Patients were stratified into 4 subgroups of 1) direct extravesical prostatic stromal involvement only in 37 patients (28%), 2) prostatic stroma and seminal vesicle involvement in 37 patients (28%), 3) seminal vesicle involvement only in 10 patients (8%) and 4) other contiguous pelvic organ involvement (stage pT4b) in 48 patients (36%). Overall 88 patients (67%) received some form of adjuvant therapy. At a median followup of 12.5 years (range 0 to 15.2) clinical outcomes were analyzed including overall and recurrence-free survival using Kaplan-Meier plots. RESULTS: There was no significant difference in clinical outcomes or prognosis for groups 2 and 3, thus they were combined for analysis. Five-year overall survival for any seminal vesicle involvement (10%) was significantly worse than prostatic stromal involvement only (38%) but was similar to pT4b tumors (7%, p <0.0001). The 5-year recurrence-free survival for seminal vesicle involvement (14%) was also significantly worse than prostatic stromal involvement alone (68%) but similar to that pT4b disease (25%, p = 0.01). Results were controlled for lymph node status. CONCLUSIONS: Patients with extravesical tumor extension into seminal vesicles and contiguous pelvic organs are at high risk for recurrence and progression. Involvement of the seminal vesicles by direct extension of bladder TCC portends a prognosis similar to that of pT4b disease and should, therefore, be classified as such.
