Summary—The phenomena of post‐obstructive diuresis and natriuresis have been studied using the lithium clearance technique in 10 patients with high pressure chronic retention. Following relief of obstruction there was a significant increase in both sodium and water excretion. There was a coincident reduction in the fractions of sodium and water reabsorbed in both proximal and distal nephron segments. This study demonstrates for the first time that following relief of chronic obstructive uropathy in man, changes in sodium and water excretion are due to altered handling in both proximal and distal nephron segme

摘要:

Summary—Routine thermogravimetric (TG) analysis of 501 upper urinary calculi from the State of Jammu and Kashmir is described. The technique is simple, rapid and quantitative, and the equipment is easily maintained. The technique was found to be helpful in 95.4% of urinary stones and it is suggested that TG analysis may be employed as a technique of first choice in the routine quantitative analysis of all urinary calcul

摘要:

Summary—Several series have suggested that the incidence of hypertension following extracorporeal Shockwave lithotripsy (ESWL) may be as high as 8%. In this study, changes in blood pressure and the incidence of hypertension have been observed in 733 patients 12 to 44 months after renal ESWL on the Dornier HM3.The incidence of hypertension following ESWL was 8.1%. In patients with a pre‐ESWL diastolic pressure100 mm Hgpost‐operatively was significantly greater than that predicted by historical data. There was no overall change in the mean blood pressure of the group.The hypertensive risk of ESWL remains unclear. However, blood pressure surveillance should be performed following ESWL and a prospective study is req

摘要:

Summary—Endoballoon rupture and stenting was performed on 31 patients with pelviureteric junction obstruction. A percutaneous antegrade approach was used in 20 patients, a retrograde technique in 11. Clinical and renographic improvement was seen in 21 patients. Four patients later underwent nephrectomy, all of whom had a GFR of less than 20% in the affected kidney.Endoballoon rupture is technically undemanding, easier and less invasive than endopyelotomy. In patients with adequate renal function it provides a suitable alternative to pyeloplast

摘要:

Summary—The features of computed tomography (CT) in 5 patients with hydatid disease of the urinary tract are described. The diagnosis of hydatid disease was based on the demonstration of unilocular or multilocular cysts with well defined walls which enhanced with contrast, which were often calcified and which contained daughter cysts within the large parent cyst. It is difficult to differentiate between a unilocular hydatid cyst without mural calcification and an infected simple renal cys

摘要:

Summary—The urine postal cytology kit Urotel was assessed against our standard cytological method; 184 patients attending for routine surveillance cystourethroscopy provided free flow urine specimens. The urine cytology was reported blind. Comparison of the 2 tests showed similar specificity but significantly higher sensitivity with the Urotel kit. These kits may have a place in the surveillance of patients at high risk of recurrent tumour or those with carcinomain situ, reducing the frequency of hospital attendanc

摘要:

Summary—Erosion and infection are major complications following implantation of the AMS 800 artificial urinary sphincter. In the present study, 17 patients with this prosthesis were investigated urodynamically. All were continent. Urethral pressure profilometry showed a significantly lower intra‐urethral pressure than would have been expected from the pressure installed in the pressure regulating balloon during operation. The maximal urethral pressure was 69.9% of the expected pressure and did not vary significantly in relation to the various balloon pressures. The mean maximal urethral pressure (± SEM) between the cuff when inflated and when deflated was also significantly different, although the absolute difference was small (14.1 cm H2O± 10.0). There was good correlation between maximal urethral pressure and urethral leakage pressure as measured by retrograde perfusion sphincterometry. The mean functional urethral length became significantly longer after implantation of the cuff.A combination of low urethral pressure and increased functional length may help to prevent cuff erosion and maintain conti

摘要:

Summary—A series of 20 women with stress urinary incontinence underwent bladder neck suspension according to the method in which there are no suprapubic or vaginal incisions and no buttresses. Follow‐up was between 9 weeks and 8 months. Twelve patients (60%) were cured, 2 (10%) were significantly improved and 6 (30%) were not improved; 3 patients had pre‐operative detrusor instability; when they were excluded the failure rate fell to 23%. These results are inferior to those obtained in this unit using the Stamey procedure, although the difference is not significant. The operation is quick and easy to perform and was well tolerated with minimal complications; we believe it is worthy of further evalu

摘要:

Summary—Many women who present with symptoms of bladder dysfunction relate the onset to the operation of simple hysterectomy.A group of 42 women undergoing simple hysterectomy was studied prospectively. Urinary symptoms, urodynamic findings and sacral reflex latencies (SRLs) were assessed pre‐and postoperatively.After hysterectomy the incidence of urinary symptoms increased from 58.3 to 75.0%. Vesicourethral dysfunction was altered in 30.6% of patients, 72.7% of whom had evidence of pelvic neuropathy as detected by SRLs.The results show that simple hysterectomy is associated with a significant incidence of postoperative vesicourethral dysfunction and that there is an identifiable neurological abnormality incurred at operation which is pertinent to the subsequent disordered void
