RESUMEN
OBJECTIVE: The aim: To evaluate the effect of decreasing post-operative anal pain and spasm on the rate of post-surgical acute urinary obstruction in patients undergoing hemorrhoidectomy. PATIENTS AND METHODS: Materials and methods: The study was conducted from April 2013 to April 2019 on 571 patients that were undergoing conventional hemorrhoidectomy. The operation was followed by using the medicated intra-anal packing and then the patients were monitored postoperatively for the first 24 hours for the incidence of postoperative urinary retention. The hypothesis of this study was that the acute urinary retention is the most common post-operative complication of the anal surgeries and that the irritation-blockade mechanism which is induced due to anal skin injury is the main cause of that obstruction. Thus, reducing the incidence of this mechanism will reduce urinary retention and post-operative pain. RESULTS: Results and conclusions: The results found that 569 (99.64%) patients were showed no signs of urinary retention with the exception of only two (0.35%) patients were showed signs of urinary retention. Finally, it was concluded that usage of medicated anal-packing methods was of benefit in decreasing the rate of postoperative urinary retention due to its effect in decreasing postoperative anal pain and spasm.
