“…An attempt was therefore made to use stents without side holes in patients with malignant ureteral obstructions. 100 For the largest available series on extrinsic ureteral obstruction that was managed with indwelling stents, multiple logistic regression analyses identified a diagnosis of cancer, poststent systemic therapy, and baseline creatinine level >1.3 mg=dL as significant predictors of stent failure. Locationlevel of obstruction was only marginally significant (P ¼ 0.06) for the proximal ureter, while degree of hydronephrosis and size of stent used were insignificant parameters.…”

Obstruction of the upper urinary tract is a problem commonly faced by practicing urologists. The constant evolution in endourology has effectively facilitated minimally invasive management of upper-tract obstruction. In a case in which malignancy is the cause of obstruction, however, the situation significantly changes. Questions arise regarding the need for relieving the obstruction, the means to accomplish this, and the benefits and drawbacks of each technique regarding both their efficacy and their impact on the patients well-being and the crucial issue of quality of life in the face of malignancy.

These authors contributed equally to the study the other side was debrided and sutured without stenting.• Both IVP and radioactive renography were performed 40, 80 and 120 days postoperatively. The operability and effectiveness of the biodegradable ureteral stent were studied thereafter. RESULTS• In Group A, hydronephrosis and hydroureter occurred and worsened postoperatively on the wounded sides in all nine beagles. The ratio of the renal partial concentration indices (RPCI) between the kidneys (unwounded side : wounded side) increased.• The ratio of the kidney washout half-time between the kidneys (unwounded side : wounded side) decreased. In Group B, neither hydronephrosis nor hydroureter was found postoperatively in the stented ureters but both occurred in the unstented ureters in all nine beagles.• The ratio of RPCI between kidneys (stented side : unstented side) increased whereas the kidney washout half-time ratio between the stented and unstented sides decreased. Differences were significant. CONCLUSION• In Group A, the new canine model for firearm fragment wounds was tested and proved to be operable and effective. In Group B, hydronephrosis and hydroureter were effectively prevented in ureters by biodegradable stent placement compared with the non-stented ureters where hydronephrosis and hydroureter occurred. The renal concentration capacity was effectively protected and the half-time of kidney washout was shortened.

“…[1][2][3][4][5][6][7][8] The effectiveness of ureteral stents has been proven since their introduction by Zimskind and associates 9 in 1967. Double-J and pigtail stents, which are presently used in urologic practices, were first introduced by Finney et al 10 in 1978, and these stents have contributed greatly to ureteral stent insertion becoming one of the most common urological procedures.…”

Recent advances in ureteral stents

Abstract: The conventional double-J stents and the concept of ureteral stenting is undergoing several changes. New generation stents will allow the physician to choose better-fitting stents according to the needs of the individual patient.
