In 2012 we started our PUL at the University of Freiburg Medical Centre Department of Urology. As suggested by the device’s design we excluded patients with a significant prostatic middle lobe from PUL treatment. However, it soon became evident that many younger patients with small prostates and LUTS (ie., the target population for PUL) had either an additional obstructive middle lobe or primary obstructive bladder neck.
For several decades, the resection of the smooth sphincter of the bladder neck has been considered the main reason for a loss of antegrade ejaculatory function after TURP. This theory on the mechanisms of ejaculation has been challenged by recent video-urodynamic findings suggesting that antegrade ejaculation operates independently of a preserved bladder neck. The current theory locates an ejaculation-related smooth muscle (musculus ejaculatorius) in the paracollicular tissue about 1 cm proximal to the verumontanum . Recently, Alloussi et al. described an ejaculation preserving resection technique (subsequently termed epTURP) leaving this particular tissue (and some dorsal tissue at the apex flanking the plate of musculus ejaculatorius) unresected in an otherwise complete radical TURP .
In the combined approach as described in our manuscript, transurethral resection is limited to the prostatic middle lobe and/ or high bladder neck, preserving the paracollicular region around the verumontanum—i.e., the musculus ejaculatorius plate.
We believe that the combination of PUL and surgical remodeling of the bladder neck/middle lobe offers a true alternative for patients with LUTS secondary to BPH. In appropriate patients (medium size prostates, moderate symptoms and functional impairment), it not only provides improved functional results and symptom relief (as compared to drugs or PUL alone), but at the same time preserves sexual function and continence.
