Gynecologic Considerations for the Urologic Surgeon.

While gynecologic malignancy is uncommon in women with conditions such as pelvic organ prolapse and bladder cancer, urologists should be acquainted with the relevant gynecologic literature as it pertains to their surgical care of female patients. While taking the patient history, urologists should be aware of prior cervical cancer screening and ask about vaginal bleeding, which can be a sign of uterine cancer. Urologic surgeons should also discuss the role of concomitant prophylactic oophorectomy and/or salpingectomy for ovarian cancer risk reduction at the time of pelvic surgery. An understanding of basic tests, such as a transvaginal sonogram, can help urologists provide comprehensive care.

Specific Changes in Brain Activity during Urgency in Women with Overactive Bladder after Successful Sacral Neuromodulation: A Functional Magnetic Resonance Imaging Study.

PURPOSE: The mechanism of sacral neuromodulation is poorly understood. We compared brain activity during urgency before and after sacral neuromodulation in women with overactive bladder and according to the response to treatment. MATERIALS AND METHODS: Women with refractory overactive bladder who elected sacral neuromodulation were invited to undergo functional magnetic resonance imaging before and after treatment. During imaging the bladder was filled until urgency was experienced. Regions of interest were identified a priori and brain activity in these regions of interest was compared before and after treatment as well as according to the treatment response. Whole brain exploratory analysis with an uncorrected voxel level threshold of p <0.001 was also performed to identify additional brain regions which changed after sacral neuromodulation. RESULTS: Of the 12 women who underwent a pretreatment functional magnetic resonance imaging examination 7 were successfully treated with sacral neuromodulation and underwent a posttreatment examination. After sacral neuromodulation brain activity decreased in the left anterior cingulate cortex, the bilateral insula, the left dorsolateral prefrontal cortex and the bilateral orbitofrontal cortex (each p <0.05). No new brain regions showed increased activity after sacral neuromodulation. Pretreatment brain activity levels in the bilateral anterior cingulate cortex, the right insula, the bilateral dorsolateral prefrontal cortex, the right orbitofrontal cortex, the right supplementary motor area and the right sensorimotor cortex were higher in women who underwent successful treatment (each p <0.05). CONCLUSIONS: Brain activity during urgency changes after successful sacral neuromodulation. Sacral neuromodulation may be more effective in women with higher levels of pretreatment brain activity during urgency.

A standardized surgical technique for removal of the Interstim tined lead.

INTRODUCTION: Explantation of the Interstim sacral neuromodulation (SNM) device is occasionally necessary. Removing the tined lead can put strain on the lead, resulting in a possible break and retained fragments. The Food and Drug Administration (FDA) released a notification regarding health consequences related to retained lead fragments. We describe a novel and safe surgical technique for removing the Interstim device and permanent lead. MATERIALS AND METHODS: We searched the Manufacturer and User Facility Device Experience (MAUDE) database for complications related to tined lead removal and searched the database of a single surgeon at our institution. Our standardized technique for tined lead removal is as follows. An incision is made over the previous lead insertion site and the lead is isolated and externalized. The fibrous encapsulation is dissected off the lead to expose the tines and ensure the lead is free from adhesions. The lead is removed by wrapping it around a curved hemostat and turning it under tension. If the lead breaks, the incision is extended and dissection is carried down to the sacral body to remove all fragments. RESULTS: Twenty-eight patients had their tined lead removed between 2009 and 2015 after being in place a median of 2.00 years (IQR 1.32-3.32 years). One lead broke (3.6%) during removal over the 6 years using our standardized approach. CONCLUSION: Permanent tined leads can break on removal and retained fragments can pose significant health consequences. Our technique standardizes the approach for removal and is safe and effective in our series.

Contemporary management of overactive bladder.

Overactive bladder is a prevalent condition with bothersome symptoms that greatly impact health-related quality of life. Despite a multitude of treatment options, many patients go untreated or undertreated. This article addresses the contemporary management of overactive bladder, including behavioral and lifestyle modifications, pelvic floor muscle therapy, biofeedback, drug therapy, neuromodulation, and botulinum toxin. We highlight the new drugs and therapies that have been brought into clinical use over the past few years, and discuss important clinical implications of therapy as well as promising new agents that are currently in advanced stages of development.
