Abstract The combination of Mohs micrographic surgery and sentinel lymph node biopsy in the treatment of penile melanoma is novel. Mohs surgery allows the removal of penile malignancies with microscopically controlled tumor-free borders, while maintaining cosmetic and functional demands through the maximal preservation of normal tissue. Sentinel lymph node biopsy minimizes the morbidity associated with inguinal node dissection. At 30 months follow-up, these two modalities together have achieved local control and regional nodal staging while minimizing functional morbidity. More >

Abstract Prostatic abscess is a rare and potentially life-threatening disease when left untreated. We report the first case of a man who developed a prostatic abscess as a long-term complication of cryoablation for primary prostate cancer. Timely diagnosis with non-contrast computed tomography (CT) scan, retrograde CT cystogram to ensure no bladder involvement, percutaneous drainage under CT-guidance, and antibiotic treatment sensitive to the causative organism were crucial for prompt recovery.

Abstract The traditional treatment of choice for urachal carcinoma has been either an open radical cystectomy or the more recently accepted extended partial cystectomy and umbilectomy. Recently a laparoscopic technique has been reported. We report for the first time a robot-assisted technique for an extended partial cystectomy with en bloc umbilectomy for the management of urachal carcinoma in a 49-year-old man. More >

Abstract Objective: The current standard of care for radiographically identified enhancing renal lesions is surgical removal. However, some of these lesions prove to be benign and did not truly warrant extirpation. Mass size has been traditionally described as a parameter to predict the malignant potential. We compiled our experience with surgically treated renal masses and correlated lesion size with final pathology.
Materials and methods: We performed a retrospective analysis of extirpative renal surgery and resultant renal mass pathology from 1998-January 2006. Nephrectomies performed for non-malignant disease or transitional cell carcinomas were excluded. Renal tumors were staged by the… More >

Abstract Introduction: To date, no study has compared postoperative pain and requirement for pain medications in open versus robot-assisted radical cystectomy. Patient reported pain and opiate use were reviewed retrospectively using prospectively collected data from postoperative day one to day of discharge.
Materials and methods: Twenty consecutive robot-assisted radical cystectomy patients were compared to the prior 20 patients who underwent open radical cystectomy. Data was collected prospectively to determine opiate requirements and pain scores in each group. Daily opiate use was converted to morphine sulfate equivalents (MSE) to facilitate comparison. A Likert pain perception scale was used to… More >

Abstract A single-layer isotropic patient-specific right/left ventricle and patch (RV/LV/Patch) combination model with fluid-structure interactions (FSI) was introduced in our previous papers to evaluate and optimize human pulmonary valve replacement/insertion (PVR) surgical procedure and patch design. In this paper, an active anisotropic model with two-layer structure for ventricle wall and tissue fiber orientation was introduced to improve previous isotropic model for more accurate assessment of RV function and potential application in PVR surgery and patch design. A material-stiffening approach was used to model active heart contraction. The computational models were used to conduct ``virtual (computational)'' surgeries More >

Abstract Wait times for medical procedures in Canada continue to be a major issue in the delivery of timely health care. Patients scheduled to undergo surgery for urological malignancies, which include prostate, bladder, kidney and testes cancer, are among the many affected populations. To address these important issues, a Surgical Wait Time (SWAT) initiative was undertaken. The SWAT initiative, whose members consist of urological oncologists, surgeons and methodologists was mandated to assess current wait times in Canada, review the relevant literature on the surgical wait times for urological cancers and then develop a consensus document that More >

Abstract Background: Prolonged surgical wait times have significant effects on a patient's psychological well-being and a negative impact on quality of life but the effect on long-term cancer control is controversial. We conducted a systematic review of the renal cancer literature to examine the best available evidence addressing the following key questions:
• What is the reported time interval for renal cancer patients from the initial surgical consultation until the day of renal cancer surgery?
• Are there recommendations/guidelines in the urological cancer literature and, if so, how do the Canadian times compare?
• Is there a known… More >

We conducted a systematic review of the bladder cancer literature to examine the best available evidence addressing the following key questions:
• What is the reported time interval for bladder cancer patients from the decision to operate until the day of bladder cancer surgery?
• Are there recommendations/guidelines in the urological cancer literature and, if so, how do the Canadian times compare?

Abstract Background: The wait times for urological cancer surgeries in Canada are beyond those recommended by the Canadian Association of Surgical Oncology. Prolonged wait times have a negative impact on patient quality of life but the effect on long-term cancer control is controversial. We conducted a systematic review of the testicular cancer literature to examine the best available evidence addressing the following key questions:
• What is the reported time interval for testicular cancer patients from the decision to operate until the day of testicular cancer surgery?
• Are there recommendations/guidelines in the urological cancer literature and, if… More >
