“…For urethral stents, 1551 publications matched the search criteria and two authors independently screened titles and abstracts resulting in 412 acceptable papers which were retrieved and read by the same authors. Only 118 were subsequently included in the database but only 21 papers actually reported on stent complications or adverse effects with 399 patients in total suffering 366 complications [18][19][20][21][22][23][24][25][26][27][28][29][30][31][32][33][34][35][36][37] .…”

Urinary stents, be it urethral or ureteral, polymeric, metallic or biodegradable, are one of the most frequently used tools in urology and they have been used for decades in prophylactic and therapeutic setting. Although relatively low invasive, they are prone to complications and adverse effects so much that complication rates up to 100% have been described. Many reviews have focused either on specific groups of patients or particular stent types, materials or designs but so far, no comprehensive review on complications has been published. To tackle this issue, a working group was set up within ENIUS (European Network of multidisciplinary research to Improve Urinary Stents) tasked with literature search in order to screen for and systematically review published stent complications in urethra (male only) and ureters (polymeric and metallic ureteral stents in both sexes) when used in obstructed systems. In this paper, we review, catalogue and summarize complications published for metallic urethral and ureteral stents.

“…Under such conditions, strictures recur in 50% [4] and Urolume insertion should probably be avoided. Recurrent strictures following wallstent placement in iatrogenic or post-catheter strictures have been reported only in a handful of cases [5][6][7][8][9][10][11]. Milroy and Allen [11] found narrowing within the lumen of the stent in 8 of their 50 patients, of whom 33 were followed up for 4-6 years.…”

“…Singh and Blandy [12] have shown that urine extravasation in the urethra can cause periurethritis and consequently increase fibrosis. In fact, in all the cases reported with recurrent urethral strictures after wallstent implantation [5][6][7][8][9][10][11], repeated urethrotomies had been carried out prior to the wallstent placement, presumably causing urine extravasation followed by an inflammatory reaction and increased scar tissue proliferation.…”

“…Es ist allgemein bekannt, daû Harnröhrenstrikturen trotz initial scheinbar erfolgreicher Therapie nach 5 bis 10 Jahren wieder auftreten. Gleiche Beobachtungen wurden von verschiedenen Autoren berichtet, die eine Fibrose innerhalb des Stents bei verschiedenen Patienten mit seit langer Zeit bestehenden Strikturen und erheblicher periurethraler Fibrose beobachteten [12,13]. Wir haben aktuell die Langzeitergebnisse der ersten 50 Patienten, die mit dem Urolum-Harnröhren-Stent behandelt wurden, veröffentlicht [9] (Abb.…”

The human urethra seems remarkably tolerant of foreign material within its lumen. Providing that a stricture has been adequately cut by means of urethrotomy, or dilated with bougies, the majority of urethras will tolerate both permanent and temporary stents with few problems. Temporary stents have the obvious advantage over permanent stents that no foreign material is left in the urethra but before these can be recommended it is essential that more clinical experience is gained and that long term results up to ten years after removal of the stent are published. Great care is also needed in the use of any sort of permanent device, either the Urolume stent, or varieties of the Strecker such as the Memotherm device. These should not be used in children and should be probably be avoided in young adults. The majority of strictures in this age group are in any case treated more easily by single stage urethroplasty procedures. The use of permanent epithelial covering stents should be limited to the bulbo-membranous urethra, with the possible exception of carefully selected sphincters strictures used in combination with an artificial urinary sphincter. Better results will be obtained by using these stents in strictures with a short history before multiple urethrotomies and dilatations have been carried out and before extensive urethral and periurethral fibrosis has occurred. This means that urethral rupture strictures are unsuitable, and in any case these are simple to deal with be means of stricture excision and primary end to end anastomosis of the urethra particularly when the stricture is in the bulbar urethra. Care must also be taken in using these devices in post-urethroplasty strictures if extensive periurethral fibrosis exists, although it has to be admitted that these stents may be very successful in some of these patients. The difficulty at the present time is our inability to define exactly which traumatic stricture or post-urethroplasty stricture will succeed and which will fail. Metal urethral stents should not be used for the first treatment of a urethral stricture. Depending on the aetiology, the site and the length of the stricture there is always a 40-50% chance that the stricture may be cured by means of a simple urethrotomy or dilatation and this should always be tried at least once before resorting to urethral stenting. There is no doubt that permanent urethral stents have an important role to play in the treatment of recurrent urethral strictures. Careful patient selection is essential in order to achieve the best results and we need more long term results before the final role of these devices in the treatment of urethral strictures can be determined. Temporary stenting of the urethra with non-epithelial covering stents is a simpler and safer treatment but at this point in time we cannot be sure how effective this treatment is and for which patients it is most successful. Long term results must be awaited before the place of these temporary devices can be defined.
