Randomized Controlled Trial Comparative Study
Doppler ultrasonography-guided pelvic plexus block before systematic needle biopsy of the prostate: A prospective randomized study.
To report a new method to block pelvic plexus and compare its efficacy with widely used periprostatic nerve block (PPNB) for transrectal ultrasonography-guided prostate biopsy. Pelvic plexuses were localized with the aid of color Doppler ultrasonography to create the pelvic block. ⋯ Administration of lidocaine in the area of the pelvic plexus under Doppler ultrasonographic guidance provides superior analgesia to PPNB, with limited morbidity during transrectal ultrasonography-guided biopsy of the prostate.

Randomized Controlled Trial
Effect of pelvic floor interferential electrostimulation on urodynamic parameters and incontinency of children with myelomeningocele and detrusor overactivity.
To evaluate safety and efficacy of transcutaneous interferential (IF) electrostimulation on voiding symptoms and urodynamic variables in children with myelomeningocele (MMC)-induced refractory neurogenic detrusor overactivity. ⋯ This study demonstrated that noninvasive IF therapy is effective in improving voiding symptoms including incontinence and UDS parameters of MMC children with neurogenic detrusor overactivity. The clinical beneficial implication of this modality is yet to be determined in larger studies.

Angiomyolipoma is a benign renal tumor that tends to grow with time and can be associated with complications, such as hemorrhage and pain, requiring active intervention. Nephron-sparing surgery for sporadic renal angiomyolipomas offers preservation of renal function and is associated with acceptable complication and recurrence rates. Preoperative embolization of the large tumors is recommended to avoid excess blood loss during surgery. We report a case of giant renal angiomyolipoma treated with preoperative embolization, followed by partial nephrectomy without complications.
