Outcomes of Transurethral Removal of Intravesical or Intraurethral Mesh Following Midurethral Sling Surgery

PURPOSE: To present outcomes of transurethral removal (TUR) of intravesical or intraurethral mesh after midurethral slings. MATERIALS AND METHODS: This was a retrospective chart review of 23 consecutive women: 20 with intravesical mesh and 3 with intraurethral mesh. RESULTS: To remove the mesh, transurethral resection with an electrode loop (TUR-E) was used in 16 women and transurethral resection with a holmium laser (TUR-H) was used in 7. The median follow-up was 2.1 months. Twenty-six percent of the women (6/23) had a mesh remnant: 6.2% (1/16) of the women treated with TUR-E and 71.4% (5/7) of the women treated with TUR-H. Of the 5 women treated with TUR-H, 3 underwent concomitant transvaginal removal. On the follow-up cystoscopic exam, a mesh remnant was observed in 3 women (1 treated with TUR-E and 2 treated with TUR-H). Vesico-vaginal fistulas were found in 2 women during and after TUR-E, respectively. Stress urinary incontinence recurred in 1 woman. CONCLUSIONS: TUR-E has a high success rate but carries a risk of bladder perforation. Complete resection using TUR-H depends on the location of the mesh and the range of motion of the instrument.

A Case of Dermal Melanocyte Hamartoma / 대한피부과학회지

Dermal melanocytosis is characterized by the presence of ectopic melanocytes in the dermis. Dermal melanocytosis assumes several morphologic forms, including the Mongolian spot, the blue nevus, the nevus of Ota, the nevus of Ito and dermal melanocytic hamartoma. Differential diagnostic features of these dermal melanocytic lesions depend on onset, course, distribution, histologic features, uniformity of pigmentation, etc. In our case, an 18-year-old girl had asymptomatic 5x3cm sized ill-defined bluish patch on left forearm since birth. Histologic examinations revealed marked increased infiltrate of pigment cells mainly in the upper dermis in Hematoxylin & eosin stain . Fontana-Masson stain and Gp 100 stain revealed marked infiltrate of melanin-containing cells in upper dermis. We report a rare case of dermal melanocyte hamartoma.
