I think the title itself is a misnomer. Prevention of a thing is done before the insult. Here the drug hyoscine is given after the transurethral resection of the prostate, so it cannot be called prevention in true sense.
The biggest lacuna of the paper is that cases have been operated on under general anaesthesia (GA). They have been given midazolam and fentanyl. We fail to understand the combination of fentanyl and morphine in a given patient which we normally do not give, as both are analgesics. Coming to the duration of action of midazolam, which is 1–6 h, and of morphine, which is 3–7 h, then how come one can assess the catheter-related bladder discomfort (CRBD) degree in any given patient, that too in immediate post-operative period? Most important is no sedation score has been considered in these patients who have undergone surgery under general anaesthesia. We all know two patients of different scores are not comparable. CRBD degree has to have fine perception of a given patient, and unless the effect of GA drugs have weaned off, how can one comment?
The authors have not reflected anywhere in the paper the number of injections of meperidine required in a given patient whether it is the treatment group or control group.
Size of the urethra, whether narrow, optical internal urethrotomy (OIU) was done or not, and which size resectoscope was used have not been taken into consideration, and these factors can cause pain.
The patients were controlled with placebo and not with oxybutynin, etc., as written in the first paragraph of page 1908. In randomization, how did they convince patient for no treatment versus treatment? Or they have hidden something in the consent form.
