METHOD OF CHRONIC CYSTITIS TREATMENT IN CHILDREN
Chronic inflammation of bladder walls is a dominant child urological disease. Despite the application of advanced therapies and treatment modalities the number of children with chronic recurrent urocystitis constitutes a significant percentage of the total number of hospitalized patients. The research aim is to analyze clinical results of child recurrent cystitis treatment through intravesical argon-ablation. Universal urethrocystoscope 17 Fr «Karl Storz», electrosurgical scalpel electrode «Electropulse S-350 RF» and «Electropulse S-350 RFPa» for inert-gas feed were applied in argon coagulation of chronic inflammation bladder walls. An electrosurgical scalpel electrode «Electropulse S-350 RF» was installed into the operating cystoscope channel. The spark-gap mode of coagulation as well as frontal and lateral gas flow was applied. The electrode was injected into the locus of the abnormal mucosal bladder. At 0,5-0,7 l/min argon flow mode, the punctual coagulation of entirely changed surface within 1,5-second period for each point was conducted, involving the following parameters: spark-gap coagulation - 85 95 W, RF current - 440 khz with pulse recurrence frequency - 20-60 khz. After coagulation a bladder in-line catheter was not required. In this case, the coagulation layer is of 1,5 ± 0,5 mm. Proposed invention ensures no intra-operative or post-operative hemorrhage (bleeding) from the region of argon coagulation and attains no coarse cicatrical changes of the bladder walls within the region of argon coagulation during the post-operation period itself. In view of the improvement of the reparative regeneration of changed bladder walls the following findings were established: (1) urinary catheterization in the post-operation period was excluded; (2) procedure and hospital stay time was decreased which in its turn affects the health related quality of a patient.
