Lingual Mucosal Graft Urethroplasty for Anterior Urethral Reconstruction

OBJECTIVE Evaluate the use of lingual mucosal graft (LMG) in anterior urethral strictures. METHODS From January 2001 to December 2006, 29 men (mean age, 48.5 yr) with anterior urethral strictures underwent graft urethroplasty with LMG. The mean length of stricture was 3.6cm. Patients with bulbar, penile, or bulbopenile strictures received one-stage dorsal free graft urethroplasties. In patients with failed hypospadias repair we performed a two-stage urethroplasty. Criteria for successful reconstruction were spontaneous voiding with no postvoid residual urine and no postoperative instrumentation of any kind. Clinical assessment included the donor site morbidity. RESULTS Mean follow-up was 17.7 mo. One-stage bulbar and penile urethroplasties without meatal involvement had an 81.8-100% success rate. Bulbopenile urethroplasties were successful in 60% of the cases, whereas one-stage urethral reconstructions in patients with meatal involvement were successful in 66.6%. The two cases of two-stage urethral reconstruction with LMG and buccal mucosal graft after failed multiple hypospadias repairs were unsuccessful. The overall early recurrence rate was 20.7%. Patients with the graft harvested from the tongue reported only slight oral discomfort at the donor site and difficulty in talking for 1 or 2 d. CONCLUSIONS The mucosa of the tongue, which is identical to the mucosa of the rest of the oral cavity, is a safe and effective graft material in the armamentarium for urethral reconstruction with potential minor risks of donor site complications. LMG may be used alone for short strictures (<5cm) or in combination with buccal mucosa when longer grafts are needed.

The Use of a Surgical Patch in the Prevention of Lymphoceles After Extraperitoneal Pelvic Lymphadenectomy for Prostate Cancer: A Randomized Prospective Pilot Study

PURPOSE Pelvic lymphadenectomy is frequently performed simultaneously with radical prostatectomy to determine lymph node status and the most frequently recorded postoperative complication is the development of a symptomatic lymphocele. This study evaluated TachoSil as an adjunct treatment in preventing lymphoceles after extraperitoneal pelvic lymphadenectomy for prostate cancer. MATERIALS AND METHODS A total of 60 consecutive patients who had undergone radical prostatectomy and pelvic lymphadenectomy were prospectively enrolled in this study. The patients were randomly assigned to a standard technique with the use of clips and electrocoagulation plus TachoSil, or to standard technique only. All patients underwent ultrasound examination on postoperative days 7, 14 and 28 to test for the development of symptomatic or asymptomatic lymphoceles. Drainage volume and duration were also recorded. RESULTS The baseline characteristics of the 2 randomized groups were well matched. Those patients in whom we used TachoSil showed a lower drainage volume with a mean total volume of 64 +/- 45 ml (range 0 to 110) vs 190 +/- 62.72 ml (range 70 to 270, p = 0.009), and had significantly fewer symptomatic and asymptomatic lymphoceles (5 vs 19, p = 0.001). Only 5 percutaneous surgical procedures to drain the lymphoceles proved necessary, 1 of which occurred in the group with TachoSil. CONCLUSIONS TachoSil seems to provide a useful additional treatment option for reducing drainage volume and preventing lymphocele development after extraperitoneal radical retropubic prostatectomy with pelvic lymphadenectomy.

Urinary and sexual outcomes in long-term (5+ years) prostate cancer disease free survivors after radical prostatectomy

BackgroundAfter long term disease free follow up (FUp) patients reconsider quality of life (QOL) outcomes. Aim of this study is assess QoL in prostate cancer patients who are disease-free at least 5 years after radical prostatectomy (RP).Methods367 patients treated with RP for clinically localized pCa, without biochemical failure (PSA ≤ 0.2 ng/mL) at the follow up ≥ 5 years were recruited.Urinary (UF) and Sexual Function (SF), Urinary (UB) and Sexual Bother (SB) were assessed by using UCLA-PCI questionnaire. UF, UB, SF and SB were analyzed according to: treatment timing (age at time of RP, FUp duration, age at time of FUp), tumor characteristics (preoperative PSA, TNM stage, pathological Gleason score), nerve sparing (NS) procedure, and hormonal treatment (HT).We calculated the differences between 93 NS-RP without HT (group A) and 274 non-NS-RP or NS-RP with HT (group B). We evaluated the correlation between function and bother in group A according to follow-up duration.ResultsTime since prostatectomy had a negative effect on SF and a positive effect SB (both p < 0.001). Elderly men at follow up experienced worse UF and SF (p = 0.02 and p < 0.001) and better SB (p < 0.001).Higher stage PCa negatively affected UB, SF, and SB (all: p ≤ 0.05). NS was associated with better UB, SF and SB (all: p ≤ 0.05); conversely, HT was associated with worse UF, SF and SB (all: p ≤ 0.05).More than 8 years after prostatectomy SF of group A and B were similar. Group A subjects (NS-RP without HT) demonstrated worsening SF, but improved SB, suggesting dissociation of the correlation between SF and SB over time.ConclusionOlder age at follow up and higher pathological stage were associated with worse QoL outcomes after RP. The direct correlation between UF and age at follow up, with no correlation between UF and age at time of RP suggests that other issues (i.e: vascular or neurogenic disorders), subsequent to RP, are determinant on urinary incontinence. After NS-RP without HT the correlation between SF and SB is maintained for 7 years, after which function and bother appear to have divergent trajectories.

Quality of life in women undergoing urinary diversion for bladder cancer: results of a multicenter study among long-term disease-free survivors.

PurposeWomen undergoing radical cystectomy (RC) and urinary diversion for bladder cancer experience substantial limitations in health-related quality of life (HRQOL). However, the level of discomfort caused by different urinary diversion has been never evaluated in long term survivors. The aim of this multicenter study is to evaluate differences in HRQOL among recurrence-free women undergoing cutaneous ureterostomy (CUS), Brickers ileal conduit (BK-IC) and Orthotopic neobladder VIP (ONB-VIP) in disease-free females treated with radical cystectomy (RC), with long-term follow up (mean 60.1 months; range 36-122 months).Materials and methodsAll consecutively treated female patients from two urological institutions who underwent RC and urinary diversion from January 2000 to December 2008, with no evidence of tumor recurrence at a minimum follow up of 36 months, were included. Patients received the European Organisation for Research and Treatment of Cancer (EORTC) generic (QLQ-C30) and bladder cancer-specific instruments (QLQ-BLM30) and the Functional Assessment of Cancer Therapy for Bladder Cancer (FACT-BL). Clinical data and questionnaire results were analyzed in order to evaluate the HRQOL differences among diversion groups.ResultsWe identified 37 females (median age: 68, range 45–82 years), including 12 status-post CUS, 16 who underwent BK-IC, and 9 who underwent ONB-VIP. Most were healthy (24/37 with no comorbidities, 4/37 Charlson 1-2, 9/37 Charlson 3 or greater – we didn’t considered bladder cancer in Charlson evaluation because bladder cancer was the main inclusion criteria). Women undergoing CUS endorsed worse FACT-BL scores compared with BK-IC and ONB-VIP patients, worse HRQOL regarding physical and emotional well-being (p=0.008 and p=0.02, respectively), and a trend toward worse EORTC QLQ-C30 scores for appetite loss and fatigue (p=0.05 for both).ConclusionsIn our study long-term disease-free females treated with CUS endorsed worse HRQOL compared with women who underwent BK-IC or ONB-VIP, mostly due to worse physical and emotional perception of their body image.

Microsurgical testis-sparing surgery in small testicular masses: seven years retrospective management and results.

OBJECTIVE To retrospectively evaluate the clinical outcomes of 20 patients diagnosed with a nonpalpable or small testicular mass (2 cm) at 2 academic urological department. Testis-sparing surgery (TSS) is currently performed routinely for the management of nonpalpable testicular masses. High reliability of frozen section examination (FSE) and high-frequency ultrasound (US) and the adoption of microsurgical techniques improved safety and feasibility of this technique. METHODS From January 2004 to March 2011, 23 patients underwent microsurgical TSS. An inguinal approach was performed in 22 cases and a suprapubic incision in one bilateral case. All procedures were performed with an operating microscope, with warm ischemia in 21 cases and cold ischemia in 2 cases. Intraoperative US was performed before opening the albuginea. Mean operative time was 89 minutes. RESULTS After mass excision, FSE was performed; only 2 seminomatous tumors were identified, and the remaining masses were benign lesions. After a mean follow-up >12 months, all patients are free of disease; no hypogonadism developed. CONCLUSIONS TSS performed using an operating microscope allowed the preservation of testes for 21 patients diagnosed with small testicular and/or nonpalpable mass (<2 cm), without evidence of disease recurrence or de novo onset. This approach could be mandatory in the treatment of bilateral tumors or in solitary testis. Maintaining fertility is not the main goal of TSS because a great number of patients affected by testicular tumors are already infertile. Esthetic outcomes and sparing hormonal function are the main reasons for TSS.

Vaginal Flap Urethroplasty for Wide Female Stricture Disease

PURPOSE As in men, female urethral stricture disease is often treated with repeat urethral dilation or internal urethrotomy but not always with good results. In nonresponsive cases surgical treatment may be useful but only a few cases are reported in the literature. We present our single institution experience with urethral reconstruction in 6 patients using an alternative vaginal inlay flap technique inspired by the Orandi technique. MATERIALS AND METHODS We treated 6 women with urethral stricture. In 5 patients stricture involved the entire middle and distal urethra, and in 1 it also involved the proximal urethra with bilateral hydronephrosis. Patients underwent urethral reconstruction using a vaginal flap with a lateral vascular pedicle that maintains the vascular axis. The flap was partially de-epithelialized to favor tissue cicatrix formation where the sutures are placed and avoid fistula formation. RESULTS Mean followup was 70.8 months. Normal micturition was achieved after catheter removal in all patients. Post-void residual urine was measured postoperatively in 3 patients. One patient had significant post-void residual urine and required intermittent self-catheterization. The remaining 5 patients required no additional treatment. CONCLUSIONS Using the vaginal wall to reconstruct large segments of the female urethra is simple and appears to have good results. Our technique preserves the vascular axis of the flap and protects the sutures. More contributions to the existing literature are needed before any further conclusions can be drawn.

Penile dermal flap in patients with Peyronie's disease: long-term results.

PURPOSE In 1995 a penile dermal flap was described as an ideal operation for penile curvature due to Peyronies disease. We report our experience with penile dermal flaps in patients with penile curvature due to Peyronies disease. MATERIALS AND METHODS Between January 2001 and May 2004, 26 potent white men with Peyronies disease underwent corporoplasty with a penile dermal flap. They were evaluated at 3, 6 and 12 months, and yearly thereafter by determination of penile length changes and residual curvature, and the International Index of Erectile Function-5. RESULTS At the maximum followup (mean 95 months, range 81 to 108) 22 of 26 patients (85%) were available for examination, of whom 14 (63.6%) had no residual curvature, and 2 (9.1%) and 7 (31.8%) had improved and worse erectile function, respectively. Nine patients (40.9%) had inclusion cysts at the surgical site, including 5 who underwent surgical cyst removal with no cyst recurrence. Only 9 of 22 patients (40.9%) were satisfied with the cosmetic and functional outcome. CONCLUSIONS Despite the attractiveness of the operation to our knowledge no other experience with this technique has been reported. Our results differ from those reported, although we tried to exactly follow the original technique of dermabrading the flap with sandpaper. Based on these results we abandoned the penile dermal flap in patients with Peyronies disease.

Elective segmental ureterectomy for transitional cell carcinoma of the ureter: long-term follow-up in a series of 73 patients

Study Type – Therapy (outcome)

Synchronous parenchymal renal tumors of different histology in the same kidney

Background: Synchronous primary cortical tumors of different histology in the same kidney are rare. Preoperative awareness of this coexistence is important, since it can help in planning the surgical approach. Purpose: To describe the imaging findings observed in five patients with two parenchymal malignant tumors of different histology in the same kidney. Material and Methods: We reviewed the pathology reports of 381 patients operated for renal tumors from January 2000 to March 2007. The medical records of all patients with multiple, synchronous, primary lesions of different histology in the same kidney were reviewed with special attention to imaging findings and indications on the nature of the disease process. Computed tomography (CT) examinations were retrospectively evaluated for tumor detection, size, location, and enhancement pattern. Results: We found seven patients with synchronous tumors of different histology in the same kidney (1.8%). Among these, five (1.3%) had two malignancies of different subtypes and represent our study group. Four had preoperative ultrasound; all had CT. Imaging allowed identification of multifocality in 4/5 cases and, in 3/4 patients with visible double tumors, recognition of differences in lesion appearance. In only one patient did the two tumors have similar enhancement patterns. Conclusion: It is possible to suspect preoperatively the presence of tumors of different histologic subtypes within the same kidney. Imaging findings may provide information regarding the presence of lesions with different aggressiveness within the kidney, which may be helpful in therapeutic planning.

Adherence to Guidelines among Italian Urologists on Imaging Preoperative Staging of Low-Risk Prostate Cancer: Results from the MIRROR (Multicenter Italian Report on Radical Prostatectomy Outcomes and Research) Study

Objective. A number of evidence-based guidelines for diagnosis and management of prostate cancer have been published. The aim of this study is to evaluate the adherence of Italian urologists to the guidelines concerning the preoperative imaging staging of prostate cancer. Methods. In October 2007 a multicentric observational perspective study called Multicentric Italian Report on Radical prostatectomy Outcome and Research (MIRROR) was started in 135 Italian urology centers. Recruitment was closed in December 2008 and 2,408 cases were collected. In this paper we have taken into consideration all examinations carried out for preoperative imaging staging, evaluating compliance with the recommendations in the American Urological Association (AUA) and European Association of Urology (EAU) guidelines. Results. Five hundred sixty-seven (53.34%) patients were not managed according to the EAU guidelines concerning T-staging, 545 (51.27%) concerning N-staging and 757 (71.21%) concerning M-staging. According to AUA guidelines, we also analyzed patients with a Gleason grade of biopsy specimens of 7: 238 (57.35%) of these patients had undergone testing for T staging, 244 (57.35%) for N-staging and 322 (77.60%) for M-staging. Conclusions. The compliance of Italian urologists with the guidelines is low, leading to an inappropriate increase in cost of care and unnecessary anxiety for the patients.
