Combination of pregabalin and Amitriptyline in management of chronic idiopathic pain following penile prosthesis implantation: a pilot study.
Article in Basic and clinical andrology, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundChronic post-penile prosthesis pain is de novo pain persisting > 2 months post-operatively. This pain is inadequately reported, poorly understood and undermanaged. The purpose of this current pilot study was to improvise a medical approach to alleviate the condition and assess the combination of Pregabalin and Amitriptyline in its management.
resultsThe study enrolled 9 patients complaining of idiopathic penile, pelvic, or scrotal pain persisting > 2 months after penile prosthesis implantation. Patients were prescribed pregabalin 75mg/12h (escalated after 1 week to 150mg/12h upon demand) and Amitriptyline 25mg once daily for 3 months. The pain was reassessed after 10, 30 and 100 days. The dose of pregabalin required and the side effects of the medication were noted. Findings revealed a significant decrease in pain duration (p = 0.007), frequency (p < 0.001), and intensity (p < 0.001); in glanular (p = 0.008), shaft pain (p = 0.046) but not scrotal (p = 0.112). Moreover, a significant decrease was found in sharp pain (p = 0.003) and pain aggravated by touch (p = 0.008) but not aching pain (p = 0.277). Additionally, significant improvement was reported in QoL (p < 0.001) and dose escalation of pregabalin to 150mg/12h was required in only 1 case (11%).
conclusionThe combination of pregabalin and amitriptyline is very effective in the management of chronic idiopathic pain following penile prosthesis implantation. However, due to the ambiguity and lack of reporting of the condition, we recommend a multicentric contribution to acknowledge the condition, and weigh its prevalence accurately, whilst evaluating the efficacy of our approach. This study received ethical approval from Ain Shams University Research Ethics Committee (REC) FWA 000017585, on 04/13/2023 (REC-FMASU@med.asu.edu.eg).
