Dorsal clitoral nerve injury following transobturator midurethral sling.

INTRODUCTION: Transobturator slings can be successfully used to treat stress urinary incontinence and improve quality of life through a minimally invasive vaginal approach. Persistent postoperative pain can occur and pose diagnostic and therapeutic dilemmas. Following a sling procedure, a patient complained of pinching clitoral and perineal pain. Her symptoms of localized clitoral pinching and pain became generalized over the ensuing years, eventually encompassing the entire left vulvovaginal region. AIM: The aim of this study was to highlight the clinical utility of conventional pain management techniques used for the evaluation and management of patients with postoperative pain following pelvic surgery. METHODS: We described a prototypical patient with persistent pain in and around the clitoral region complicating the clinical course of an otherwise successful sling procedure. We specifically discussed the utility of bedside sensory assessment techniques and selective nerve blocks in the evaluation and management of this prototypical patient. RESULTS: Neurosensory assessments and a selective nerve block enabled us to trace the source of the patient's pain to nerve entrapment along the dorsal nerve of the clitoris. We then utilized a nerve stimulator-guided hydrodissection technique to release the scar contracture. CONCLUSION: This case demonstrates that the dorsal nerve of the clitoris is vulnerable to injury directly and/or indirectly. Assimilation of a time-honored pain management construct for the evaluation and management of patients' pain may improve outcomes while obviating the need for invasive surgery.

Clitoral Epidermal Inclusion Cyst Resection With Intraoperative Sensory Nerve Mapping Technique.

BACKGROUND: Despite the ever increasing popularity of labial and clitoral surgeries, the best practices and long-term effects of reconstructive procedures in these regions remain unknown. This is particularly noteworthy because the presentation of nerve-related symptoms may be delayed up to a year. Despite the convention that these surgical procedures are low risk, little is known about the best practices that may reduce the postoperative complications as a result of these reconstructive surgeries. We describe a preoperative sensory mapping technique in the context of a symptomatic inclusion cyst in the clitoral region. This technique delineates anatomical and functional regions innervated by the dorsal clitoral nerve while minimizing the vascular watershed area in the midline. CASE: A prototypical case of a patient with a clitoral mass is discussed with clinical history and surgical approach. Prior to surgical excision, the dorsal clitoral nerve distribution was mapped in order to avoid a surgical incision in this sensual zone. CONCLUSIONS: In our practice, preoperative sensory mapping is a clinically useful planning tool that requires minimal instrumentation and no additional operating time. Sensory mapping allows identification of the functional zone innervated by the dorsal clitoral nerve, which can aid in minimizing damage to the area.
