Objective: The aim of the study was to compare the endoscopic versus percutaneous approach (blind) to control the obturator jerk in patients undergoing transurethral resection of bladder tumors under spinal anesthesia. Materials and methods: A prospective observational study was performed in Department of Urology, Chittagong Medical College, Chittagong and some Private Hospitals (Ltd.) in Chittagong city during the period from January 2016 to June 2016. Total 100 patients were grouped into two, on alternate basis. Fifty(50) patients in group- A conducted with endoscopic infiltration with 20ml of injection 2% lignocaine at the bladder tumor base and another 50 patients in group-B, conducted with blind percutaneous technique with same drug and volume ( 20ml inj.2% lignocaine) to control obturator jerk. Severity of obturator jerk in both procedure, percentage of complete resection, ONB procedure related time, ONB procedure related complications and surgeon’s satisfaction level were recorded and compared between two approaches. Chi-square analysis was performed to compare the ease of approach and outcome of the two techniques. A value of P<0.05 was considered statistically significant. Results: The mean age of the patients were 59.44+7.681. In group-A, 50 patients were given inj. 2% lignocaine endoscopically at the bladder tumor base to control obturator jerk. Twenty five patients (50%) had no jerk, 20 patients(40%) developed mild jerk and 5 patients (10%) developed moderate jerk and no patients developed severe jerk. Second attempt was taken in moderate jerk patients (5 patients) and succeeded in 3(6%) patients. So, in this group, complete resection of bladder tumor was possible in 96%. In group B, complete resection of bladder tumor was possible in 84%. Statistical analysis was done and result is significant in case of endoscopic procedure to control obturator jerk(p<0.05). ONB Procedure related time was <20 mins. in 32(64%) patients in group-A and 45 (90%) patients in group- B. 20 mins. or more time was required for 18 (36%) patients in group-A and 5 (10%) patients in group-B. Statistical analysis was done and result is significant in percutaneous (blind) technique (p<0.05). ONB procedure related complications in group-A and Group –B were noted. Statistical analysis was done and result is insignificant (p>0.05). Surgeons satisfaction level were recorded on the basis of obturator jerk block and complete resection and which was statistically significant in favour of endoscopy group (p<0.05). Conclusion: It is concluded that endoscopic injection of 2% lignocaine into the bladder tumor base is better in case of jerk elimination and complete resection than blind percutaneous approach. Though, ONB procedure related time was significantly less in percutaneous group. Bangladesh Journal of Urology, Vol. 21, No. 2, July 2018 p.120-126

Provisional Stenting

Coronary bifurcation lesions represent an area of ongoing challenges in interventional cardiology, mainly due to the higher rate of residual stenosis and restenosis at the side branch ostium. Multiple two-stent bifurcation strategies, including T-stenting, V-stenting, simultaneuos kissing stenting, culotte stenting and classic crush techniques, have no advantages over one-stent techniques. This led to provisional stenting being considered as a mainstream approach, based on the results of numerous randomised trials. Dedicated bifurcation stents have been designed specifically to treat coronary bifurcations with the aim of addressing some of the shortcomings of the conventional percutaneous approach and facilitating the provisional approach. The development of more drug-eluting platforms and larger studies with control groups demonstrating their clinical applicability, efficacy and safety are required before these stents are widely incorporated into daily practice.

The aim of this study is to assess the efficiency and safety of the tranexamic acid in reducing hemmorrhagic complications and transfusion requirements in patients with renal lithiasis treated by percutaneous approach. Percutaneous nephrolithotomy (PCNL) is a minimally invasive technique used for large kidney stones (]20mm). Urinary sepsis and intra or postoperative bleeding are the very serious complications associated with this type of procedure. Tranexamic acid is used in the treatment of many haemorrhagic conditions. The experience with tranexamic acid in preventing bloodloss during percutaneous nephrolithotomy is very limited. The use tranexamic acid in percutaneous nephrolithotomy is safe and is associated with reduced blood loss and a lower transfusion rate.

The genus Homalopteroides Fowler 1905 is resurrected and distinguished from the genus Homaloptera van Hasselt 1823based on a combination of characters including a unique mouth morphology, dorsal-fin origin over pelvic fin,≤60 lateral-line scales, and≤30 predorsal scales. Species included in Homalopteroides are H. wassinkii (Bleeker 1853), H. modestus(Vinciguerra 1890), H. rupicola (Prashad & Mukerji 1929), H. smithi (Hora 1932), H. stephensoni (Hora 1932), H. weberi(Hora 1932), H. tweediei (Herre 1940), H. indochinensis (Silas 1953), H. nebulosus (Alfred 1969), H. yuwonoi (Kottelat1998), and possibly H. manipurensis (Arunkumar 1999). Homalopteroides modestus (Vinciguerra 1890) is a poorlyknown species that was originally described from the Meekalan and Meetan rivers of southern Myanmar. It occurs in theSalween, Mae Khlong, and Tenasserim basins, and can be distinguished from all other species of Homalopteroides by thecombination of caudal-fin pattern (black proximal and distal bars, median blotch), 15 pectoral-fin rays, pectoral-fin lengthgreater than head length, 5½–6½ scales above and 5–6 scales below the lateral line (to the pelvic fin), 39–44 total lateral-line pores, no axillary pelvic-fin lobe, pelvic fin not reaching anus, orbital length less than interorbital width in adult, and maxillary barbel reaching to or slightly past the anterior orbital rim.

OBJECTThis study proposes a variation of the transorbital endoscopic approach (TOEA) that uses the lateral orbit as the primary surgical corridor, in a minimally invasive fashion, for the posterior fossa (PF) access. The versatility of this technique was quantitatively analyzed in comparison with the anterior transpetrosal approach (ATPA), which is commonly used for managing lesions in the PF.METHODSAnatomical dissections were carried out in 5 latex-injected human cadaveric heads (10 sides). During dissection, the PF was first accessed by TOEAs through the anterior petrosectomy, both with and without lateral orbital rim osteotomies (herein referred as the lateral transorbital approach [LTOA] and the lateral orbital wall approach [LOWA], respectively). ATPAs were performed following the orbital approaches. The stereotactic measurements of the area of exposure, surgical freedom, and angles of attack to 5 anatomical targets were obtained for statistical comparison by the neuronavigator.RESULTSThe LTOA provided the smallest area of exposure (1.51 ± 0.5 cm2, p = 0.07), while areas of exposure were similar between LOWA and ATPA (1.99 ± 0.7 cm2 and 2.01 ± 1.0 cm2, respectively; p = 0.99). ATPA had the largest surgical freedom, whereas that of LTOA was the most restricted. Similarly, for all targets, the vertical and horizontal angles of attack achieved with ATPA were significantly broader than those achieved with LTOA. However, in LOWA, the removal of the lateral orbital rim allowed a broader range of movement in the horizontal plane, thus granting a similar horizontal angle for 3 of the 5 targets in comparison with ATPA.CONCLUSIONSThe TOEAs using the lateral orbital corridor for PF access are feasible techniques that may provide a comparable surgical exposure to the ATPA. Furthermore, the removal of the orbital rim showed an additional benefit in an enhancement of the surgical maneuverability in the PF.
