RETAINED foreign bodies in the urinary tract after surgical or diagnostic procedure, named iatrogenic foreign bodies, are rarely reported, though the estimated incidence was as high as 1/1500 cases.1 Prompt and proper retrieval is required due to potential complications. We report a case of iatrogenic foreign body into the bladder.

SINCE the introduction of double J stents in 1978, ureteral stents have become an integral tool in treating ureteral obstruction from calculi and other causes.1 Owing to the widespread usageof indwelling ureteral catheters, a number of possible complications such as migration, infection, pyelonephritis, breakage, encrustation, stone formation, and ureteral stents fragmentation have been noted.2 Of all the complications, ureteral stent fragmentation was sporadically reported and believed to be rare. Here we present a case of fragmentation of a new type of double J stent, which was used to provide free drainage to the bladder after balloon dilation.

DRIMARY benign ureteral tumors are rare and they arise from the mesodermal tissue of the ureteral wall. Less than 200 cases have been docu- mented in published reports.1 Bilateral ureteralfibroepithelial polyps are extremely rare and commonly occur in the proximal ureter, causing complete ureteral obstruction. Pyeloplasty is an effective treatment for im- proving renal function. Here we report a case with se- quential bilateral ureteral fibroepithelial polyps causing obstructive hydronephrosis.

Pulsar timing array(PTA) provides an excellent opportunity to detect the gravitational waves(GWs) in nanoHertz frequency *** particular, due to the larger number of "arms" in PTA, it can be used to test gravity by probing the non-Einsteinian polarization modes of GWs, including two spin-1 shear modes labeled by "sn" and "se", the spin-0 transverse mode labeled by "b" and the longitudinal mode labeled by "l". In this paper, we investigate the capabilities of the current and potential future PTAs, which are quantified by the constraints on the amplitudes parameters(c_b, c_(sn), c_(se), c_l), by observing an individual supermassive black hole binary in Virgo cluster. We find that for binary with total mass M_c= 8.77 × 10~8 M_⊙ and GW frequency f = 10^(-9) Hz, the PTA at current level can detect these GW modes if c_b> 0.00106, c_l> 0.00217, c_(se)> 0.00271, c_(sn)> 0.00141, which will be improved by about two orders if considering the potential PTA in SKA era. Interesting enough, due to effects of the geometrical factors, we find that in SKA era, the constraints on the l, sn, se modes of GWs are purely dominated by several pulsars, instead of the full pulsars in PTA.
