Radical Cystectomy after BCG Immunotherapy for High-Risk Nonmuscle-Invasive Bladder Cancer in Patients with Previous Prostate Radiotherapy.

Purpose. Intravesical Bacillus Calmette-Guerin (BCG) immunotherapy is indicated for high-grade nonmuscle-invasive bladder cancer (NMIBC). The efficacy of BCG in patients with a history of previous pelvic radiotherapy (RT) may be diminished.

Cotransplantation with specific populations of spina bifida bone marrow stem/progenitor cells enhances urinary bladder regeneration.

Spina bifida (SB) patients afflicted with myelomeningocele typically possess a neurogenic urinary bladder and exhibit varying degrees of bladder dysfunction. Although surgical intervention in the form of enterocystoplasty is the current standard of care in which to remedy the neurogenic bladder, it is still a stop-gap measure and is associated with many complications due to the use of bowel as a source of replacement tissue. Contemporary bladder tissue engineering strategies lack the ability to reform bladder smooth muscle, vasculature, and promote peripheral nerve tissue growth when using autologous populations of cells.

Intravesical bacillus Calmette-Guerin immunotherapy after previous prostate radiotherapy for high-grade non-muscle-invasive bladder cancer.

Objectives: Intravesical bacillus Calmette-Guerin (BCG) immunotherapy is a standard treatment for high-grade non-muscle-invasive bladder cancer (NMIBC). We evaluated outcomes of BCG therapy for NMIBC in patients with a previous history of prostate cancer (CaP) radiotherapy (RT).

Materials And Methods: A retrospective review of patients with a history of CaP RT who subsequently underwent treatment with intravesical BCG for high-grade NMIBC was performed.

Updates on the use of ureteral stents: focus on the Resonance(®) stent.

The Resonance(®) metallic ureteral stent is one of the latest additions to the urologist's armamentarium in managing ureteral obstruction. One advantage of this stent over traditional polymer-based stents is resistance to encrustation with stone material, which allows longer dwell times and less frequent exchange procedures. Although exchanging a metallic stent is slightly more complicated than exchanging a polymer stent, the fluoroscopic techniques required are familiar to most urologists.

Penile myofibroma occurring in a dorsal hood prepuce.

Dorsal hood prepuce is a common congenital anomaly of the penis. Neoplasms of the prepuce are very rarely seen in children. We present an interesting case of a penile myofibroma encountered during circumcision of a dorsal hood foreskin in an 8-month-old infant.

Right renal vein aneurysm discovered incidentally during laparoscopic nephrectomy.

Renal vein aneurysms are exceedingly rare. There are only 8 reported cases in the literature. We present the first case of a renal vein aneurysm discovered incidentally during a laparoscopic radical nephrectomy and discuss its intraoperative management.

Renal cell carcinoma in two patients with crossed fused ectopic kidneys.

Primary renal malignancies involving crossed fused ectopic kidneys have rarely been reported. We describe two cases of renal cell carcinoma involving the orthotopic renal moiety in one patient and the heterotopic crossed renal moiety in another patient. Both patients were treated with surgical excision and preservation of the uninvolved renal unit.
