Suspension Suture Materials and Suture Carrier in Modified Gittes Bladder Neck Suspension / 대한비뇨기과학회지

We reviewed 42 cases (mean age 48.3+/-7.6 years, range 30 to 63 years) who underwent the modified Gittes bladder neck suspension for female stress urinary incontinence between January 1990 and May 1995 to evaluate the efficacy of two different suspension suture materials and new suspension suture carrier. At first we used the No. 1-0 Prolene as suspension suture in 24 cases (group I) and secondly No. 1-0 Ethibond in 18 cases (group II) with Ostycut bone biopsy needle (Angiomed) as suture carrier Following results were obtained. 1. The patient's ages ranged from 30 to 63 years (mean age 48.3+/-7.6 years), and most patients were multiparous with an average of 3.3+/-1.2 deliveries and we classified the patients according to Blaivas classification and there was statistically no difference of variables in both groups except the parity. 2. The mean values of operative time, postoperative days on catheter, and postoperative hospitalization were 65.5+/-11.4 minutes, 6.9+/-1.6 days, 7.3+/-1.4 days respectively. 3. The postoperative complications were transient urinary retention 8 cases (21.1%), vaginitis or cystitis 5 cases (11.9%), wound bleeding 1 case (2.4%) and deviation of urinary steam 1 case (2.4%). 4. The success rate was 83.3% in the group I, 94.4% in group II with minimum followup of 12 months (mean 24.6+/-5.0 months) but the latter wasn't significantly higher than the former statistically. The overall success rate was 88.1%. 5. The Ostycut bone biopsy needle as suspension suture carrier was simple and safe in the bladder neck suspension treatment. With above results, we recommend the No. 1-0 Ethibond as suspension suture material rather than the Prolene in bladder neck suspension and Ostycut bone biopsy needle as suspension suture carrier.

Assessment of CT-Guided Bone Biopsy in Extremities(A Report of 50 Cases) / 实用放射学杂志

Objective In this article we report our methods and effects of CT-guided bone biopsy in extremities.Methods 50 patients with extremital bone lesion were candidates for CT-guided biopsy.Two or more procedures were routinely performed in each case.Ackmann drill was used for 13 patients with sclerotic lesions.Temno core needle was used for 42 cases.Fine needle aspiration was combined for 12 patients with cystic or obviously liquefied lesions.Results In the 50 cases,a diagnosis was possible in 88%(44/50).The six unsatisfactory results were from sclerotic lesions(n=3),liquefied lesions(n=2) and mixed lesion(n=1).50cases were divided into primary malignant tumors(n=23),primary benign tumors and tumor-like lesions(n=12),metastatic tumors(n=8),and bone inflammations (n=7).Their diagnostic accuracies of CT-guided biopsy were 91%,83%,100% and 71% separately.No severe complications were observed in our series.Conclusion CT-guided extremital bone biopsy is a safe,accurate and effective method.Bone drill,needle core and fine needle aspiration should be slected according to the type of bone lesions.In order to increasing its accuracy,the operator should avoid necrotic areas and select more then one point to get samples.One modality can be performed concomitantly with other one in the evaluation of bone lesions,since the three modalities are complementary.
