RESUMEN

INTRODUCTION AND IMPORTANCE: Blunt traumatic injury to the genitourinary system is uncommon. Urinoma formation may occur in patients with blunt trauma after high grade renal injuries. In such cases, the presence of solitary kidney must be ruled out as it may affect treatment decisions. CASE PRESENTATION: A 21 years old male presented to our facility with complaints of abdominal pain and frank hematuria following physical assault. Physical examination revealed tenderness at the right flank. Laboratory evaluation showed a decreased hemoglobin level and urinalysis showed proteinuria and marked hematuria. Imaging findings were consistent with AAST Grade IV right renal injury affecting the renal pelvis with urinoma formation and congenital megacalyces. Incidental finding of unilateral renal agenesis on the left side was also noted. Our patient underwent Ureteroscopy with double-J stenting. Subsequent ultrasonography after the procedure showed resolution of the perirenal collection. DISCUSSION: The presence of solitary kidney must be ruled out in cases of high grade renal trauma as operative procedures may lead to catastrophic consequences in such cases. Urinoma formation after renal trauma may occur if the renal pelvis is injured and should be managed preferably by urinary diversion in the form of ureteral stenting over other operative procedures, especially in patients with anomalous solitary kidney. CONCLUSION: Presence of bilateral kidneys should be confirmed before subjecting patients with high grade renal injury to operative procedures. Early ureteric stenting appears to be an effective method of urinary diversion for management of symptomatic urinomas in patients with anomalous solitary kidney.

RESUMEN

PURPOSE: This study aimed to compare the safety and efficacy of tamsulosin and tadalafil as medical expulsive therapy for distal ureteral stones. MATERIALS AND METHODS: This prospective randomized study was conducted at the Department of Urology of Bir Hospital over a period of 12 months in patients with distal ureteral stones sized 5 to 10 mm. Patients were randomly divided into 2 groups: group A received tamsulosin 0.4 mg and group B received tadalafil 10 mg at bedtime for 2 weeks. Stone expulsion rate, number of ureteric colic episodes and pain score, analgesic requirements, and adverse drug effects were noted in both groups. Statistical analyses were performed by using Student t-test and chi-square test. RESULTS: Altogether 85 patients, 41 in group A and 44 in group B, were enrolled in the study. The patients' average age was 31.72±12.63 years, and the male-to-female ratio was 1.5:1. Demographic profiles, stone size, and baseline investigations were comparable between the 2 groups. The stone expulsion rate was significantly higher in the tadalafil group than in the tamsulosin group (84.1% vs. 61.0%, p=0.017). Although the occurrence of side effects was higher with tadalafil, this difference was not significant (p=0.099). There were no serious adverse effects. CONCLUSIONS: Tadalafil has a significantly higher stone expulsion rate than tamsulosin when used as a medical expulsive therapy for distal ureteral stones sized 5-10 mm. Both drugs are safe, effective, and well tolerated with minor side effects.

RESUMEN

A dwarfing gene (allele) sd1-d has been intensively utilized to develop short-culm indica varieties in southeast Asia up to now. Before the first sd1-d-carrying variety IR8 was released, rice researchers had recognized the general tendency that culm length is higher in indica varieties than in temperate-japonica ones. Inter-subspecific difference of the tall (wild-type) allele SD1 at the sd1 locus was examined on the common genetic background, using five isogenic lines developed by substituting sd1-d of the recurrent parent IR36 by SD1s of two indica varieties, two temperate-japonica varieties and one tropical-japonica variety. The two indica -donor isogenic lines had longer culms than the three japonica-donor isogenic lines consistently in two different environmental conditions. Moreover, nonsynonymous single-nucleotide polymorphism between the two subspecies was detected at two sites in Exon 1 and Exon 3 of the sd1 locus. It is demonstrated that the inter-subspecific differentiation of SD1 contributes height difference between indica and japonica. The indica-originating and japonica-originating alleles at the sd1 locus were designated as SD1-in(t) and SD1-ja(t), respectively.
