ABSTRACT
The traditional arthroscopy technique includes the creation of three ports in order to enable visualization, operation, and arthrocentesis. The aim of this study was to assess an advanced temporomandibular joint (TMJ) arthroscopy technique that requires only a single cannula, through which a one-piece instrument containing a visualization canal, irrigation canal, and a working canal is inserted, as an alternative to the traditional double-puncture technique. This retrospective study assessed eight patients (13 TMJs) with pain and/or limited range of movement that was refractory to conservative therapy, who were treated between June 2015 and December 2015. The temporomandibular joint disorder (TMD) was diagnosed by physical examination and mouth opening measurements. The duration of surgery was recorded and compared to that documented for traditional arthroscopies performed by the same surgeon. Operative single-cannula arthroscopy (OSCA) was performed using a holmium YAG (Ho:YAG) 230µm fibre laser for ablation. The OSCA technique proved effective in improving mouth opening in all patients (mean increase 9.12±1.96mm) and in reducing pain (mean visual analogue scale decrease of 3.25±1.28). The operation time was approximately half that of the traditional technique. The OSCA technique is as efficient as the traditional technique, is simple to learn, and is simpler to execute.

The incidence and severity of urinary tract infections in 145 patients with renal calculi undergoing extracorporeal shock wave lithotripsy (ESWL*) who were catheterized for a short period without evidence of bacteriuria and/or infected stones evaluated. The patients were followed clinically and bacteriologically 1 and 14 days after the procedure. Bacteriuria was observed in 7 of the 145 patients (4.8%): in 5 patients 24 hours after ESWL and in 2 patients 2 weeks later. Of these patients 2 were symptomatic but only 1 had fever. No patient was hospitalized. We found no correlation between bacteriuria and the number or size of the stones. We conclude that the incidence of bacteriuria in catheterized patients who underwent ESWL without urinary tract infection is low and the use of antibiotics in these patients is probably not indicated.
