Abstract
BACKGROUND Temporary ureteric stent insertion is an integral part of modern endo-urological practice. Delayed stent removal or forgotten stents are associated with increased patient morbidity and complications which are often difficult to manage. METHODS AND RESULTS We prospectively audited our ureteric stent insertion and removal logbook system to determine the value and effectiveness of our stent follow-up. Over a 1-year period, 210 ureteric stents were inserted in our urological unit. Of these, 47 (22.4%) patients were unaccounted as having their stents removed within the stent logbooks. One patient was lost to follow-up and re-presented with stent encrustation 10 months later. CONCLUSIONS Our results in this audit suggest that our system of ureteric stent follow-up is not effective. We have now introduced a new system that we feel is a safer and a satisfactory alternative to the stent logbooks. This includes a patient education leaflet and removal date scheduling prior to discharge from hospital.

Abstract
BACKGROUND Out-patient non-attendance leads to inefficiency and patient morbidity. AIMS AND METHODS A phone survey of urology out-patient non-attenders over 1-month was performed to determine reasons for non-attendance, to identify patients who could be discharged, and the manner in which patients want reminders. RESULTS Seventy-six non-attenders were contacted. Fourteen were GP referred new patients. The reason for non-attendance (n = 10) was due to patient issues. Of the patients due for review (n = 62), it was a first non-attendance in 56. Only 41 (66%) claimed to have received notification or appointment cards. Eight patients said they were written to and 13 (21%) denied either receiving a written notification or an appointment card. Only eight patients rang to confirm/change their appointment. Ninety-nine percent said that they would like a further appointment by text message (34%), phone (37%), letter (36%) or email (6%). CONCLUSIONS We now hope to implement a number of methods to further reduce non-attendance rates based on the findings in this study.

Abstract
BACKGROUND At the national Stone Centre we have adopted a proactive management approach involving early ureteroscopy for ureteric calculi. As the efficacy of ureteroscopy is known this study focuses on the low intra-operative complication rate as justification for a proactive management protocol. PATIENTS AND METHODS A retrospective study (1987-1997) identified 1936 patients undergoing 2273 ureteroscopies. A database was created from inpatient hospital records. The male to female ratio was 3 to 1, age range was 25 to 84 years. RESULTS Twenty-three patients (1%) had an intra-operative complication during ureteroscopy. Immediate ureteric JJ stenting was performed in 16 cases with ureteric injury. Two cases underwent percutaneous drainage and delayed antegrade ureteric stenting, ureteroscopy was terminated because of poor visibility. Five patients (0.22%) underwent open surgery for: ureteric perforation (n = 2); Dormia basket ureteric avulsion (n = 1); impacted Dormia basket and stone (n = 1); and impacted balloon dilator and stone (n = l). Ureteroscopic complications were not related to the level of ureteric calculus. CONCLUSION A protocol of proactive management of ureteric calculi facilitates rapid turnover of large patient numbers. This approach is supported by the low intra-operative complication rate, most of which can be managed by further endoscopic procedures. In the event of corrective open surgery a favourable outcome has resulted.

Abstract
In this paper we describe the effect of poly-L-lysines of different molecular weight on the schistosomula. In the control sample, the schistosomula of Schistosoma mansoni take up fluorescent Texas Red conjugated to bovine serum albumin (TxR-BSA) into the gut. Following slight damage by 24.0 kDa poly-L-lysine, a high proportion of schistosomula take up fluorescent TxR-BSA into the excretory system. Subsequently, the dye diffused into the bodies of the schistosomula. We suspected that this diffusion involved the process of endocytosis so we investigated this with the use of endocytosis inhibitor, Latrunculin A. Addition of the endocytosis inhibitor Latrunculin A following poly-L-lysine treatment inhibited gut uptake of TxR-BSA as well as the diffusion of excretory-ingested TxR-BSA molecules.

Abstract
The fluorescent probe LysoTracker Red was used to examine for the presence of acidic vesicles in cercariae and schistosomula of Schistosoma mansoni. Acidic vesicles were widely distributed throughout the body of freshly transformed schistosomula and 24-h-old schistosomula but were absent from cercariae. The vesicles of freshly transformed schistosomula were undetectable after incubation with drugs that affect the functionality of acidic vesicles including monensin, ouabain, primaquine, and amiloride. In 24-h transformed schistosomula, the same effect was observed with monensin but not with ouabain, primaquine or amiloride. Praziquantel also affected the acidic vesicles of the schistosomula. We suggest that these acidic vesicles could be large lysosome-like organelles.

Abstract
BACKGROUND Management of traumatic rupture of the male membranous urethra remains controversial. Long-term morbidity can include urinary incontinence, urethral stricture and erectile dysfunction. AIMS To review management and outcome of urethral rupture to improve treatment protocols. METHODS A retrospective study of 47 patients presenting with traumatic urethral rupture over 25 years was performed. RESULTS All patients underwent emergency suprapubic catheterisation, 32 patients had open surgical realignment at 1-2 weeks; 78% of whom developed strictures. Ten patients unsuitable for early repair underwent delayed transabdominal transpubic urethroplasty at three months: 40% of whom developed strictures. Five patients with partial rupture were managed by cystoscopy and urethral catheter. Erectile dysfunction correlated to initial injury rather than treatment. CONCLUSIONS If the patient is stable and requires emergency laparotomy for other abdominal injuries, he should have immediate realignment of the urethra. Early realignment of the urethra at laparotomy at 1-2 weeks can be combined with orthopaedic fixation of pelvic fractures. Patients who remain unstable due to associated injuries should have delayed urethroplasty at three months.

Abstract
As is the case in many parasite infections, research into schistosomiasis has not yet yielded a vaccine and, although chemotherapy with praziquantel is very effective, the mechanism of action of this drug is unknown. John Kusel and colleagues here suggest that an understanding of basic biological phenomena, such as the role of Ca(2+) in skin penetration and the function of the adult excretory system, might lead to important breakthroughs. Other crucial questions are also addressed, with the hope of stimulating debate. They invite suggestions and correspondence from others working in related fields.

Abstract
Supravesical urinary diversion without cystectomy is a common procedure performed to manage a variety of lower urinary tract pathologies. The purpose of this article is to review the complications associated with the bladder left in situ and to relate this to the female patient. Complications related to the defunctionalized bladder include pyocystis, hemorrhage, pain/spasm and neoplastic transformation. The defunctionalized bladder also has implications for sexual function, pregnancy and undiversion. The risk factors for complications are chronic infection, inadequate drainage, interstitial cystitis and previous irradiation. The incidence of neoplastic change in the defunctionalized bladder is low, but long-term follow-up is advised, as carcinoma could develop many decades after diversion. Sexual function following urinary diversion is better preserved when the bladder is retained.

Abstract
OBJECTIVE To assess the outcome of epididymectomy as a method of treating epididymal pathology. PATIENTS AND METHODS Forty-one patients who underwent epididymectomy between 1990 and 1995 were analysed retrospectively; their clinical records were reviewed and their satisfaction with the outcome and relief of symptoms assessed using a questionnaire and/or telephone interview. RESULTS Twenty-nine patients with pain were subdivided into three categories depending on the indication for epididymectomy, i.e. post-vasectomy epididymal engorgement (eight patients), complex cystic disease (11) or 'chronic epididymitis' (10). The outcome was satisfactory in 27 of the 29 patients. The best results were obtained in the group who underwent epididymectomy after vasectomy, where seven of eight improved after the procedure. Those with chronic epididymitis had the least favourable outcome, with only seven reporting any improvement in symptoms. CONCLUSIONS Epididymectomy has a valuable role in the management of epididymal pathology in appropriately selected patients.

Abstract
PURPOSE Owing to the risk of future malignancy, many postpubertal male subjects presenting with unilateral cryptorchidism undergo orchiectomy rather than orchiopexy. We examined the incidence of spermatogenesis and carcinogenesis in whole orchiectomy specimens removed from postpubertal cryptorchid male subjects. We review the concept that orchiectomy is justifiable in these patients. MATERIALS AND METHODS A total of 52 patients with postpubertal cryptorchidism (unilateral in 48, bilateral in 4) were retrospectively analyzed from 1984. Patient age ranged from 15 to 66 years (mean 26). Six patients presented with primary infertility (unilateral in 3, bilateral in 3). The undescended testicles were palpable in 32 cases (62%). All patients underwent unilateral orchiectomy and whole specimens were examined histologically. RESULTS Histology showed normal spermatogenesis in only 1 orchiectomy specimen, while 15 had maturation arrest, 6 testicular agenesis and 30 seminiferous tubular atrophy and/or Sertoli-cell-only syndrome with no spermatogenesis. The location of the undescended testis was the superficial inguinal pouch in 32 cases, inguinal canal in 6 and inside the deep ring in 8. Absent spermatogenesis was significantly associated with a high level of maldescent and with increasing age. Two patients (4%) had carcinoma in situ of the testicle. Torsion of an undescended testicle occurred in 1 patient (2%). CONCLUSIONS This analysis of cryptorchid testes in postpubertal male subjects confirms that the majority cannot contribute to fertility, have significant malignant potential and may undergo torsion. Therefore, orchiectomy remains the treatment of choice for the majority of postpubertal male subjects presenting with unilateral cryptorchidism.

Abstract
Stroke occurs in all age groups, ranging from the new-born to the elderly. Our current understanding of the mechanisms of ischemic brain injury suggests that, despite age, the underlying cascade of events includes the rapid depletion of energy reserves, lactate accumulation, release of excitatory amino acids, high intracellular concentrations of Ca2+, and the production of oxygen free radicals. The extent to which these events affect brain injury, however, is profoundly influenced by age. Hyperglycemia for example, markedly enhances hypoxic-ischemic brain damage in adults, but has a protective effect in new-born rats. Insulin-induced hypoglycemia, on the other hand, protects the adult brain, but may be detrimental to the new-born. Substrate utilization of ketone bodies is markedly enhanced in the new-born, and has now been shown also to protect the brain. The immature brain is generally believed to be more resistant to the damaging effects of cerebrovascular compromise compared to the more mature brain. However, recent experiments suggest that the correlation between brain damage and age is not linear. To further clarify the effects of age and development on hypoxic-ischemic brain damage, we developed a model whereby rats of increasing age received identical cerebrovascular insults. Neuropathologic assessment at 7 days of recovery showed that brain damage was most severe in the 1- and 3-week-old animals followed by those that were 6 months. The 6- and 9-week-old groups had significantly less injury than the other three age groups. Hippocampal damage was most severe in the 3-week and 6-month-old rats compared to all other age groups. These findings contrast previously held beliefs regarding the enhanced tolerance of the immature brain to hypoxic-ischemic damage and demonstrate that the immature brain is, in fact, less resistant to hypoxic-ischemic brain damage than its adult counterpart. The results emphasize the need for a greater understanding of the effects of ontogeny on hypoxic-ischemic brain damage, particularly as it pertains to the development of therapeutic interventions.

Abstract
OBJECTIVES AND METHODS The effects of double pigtail ureteric catheters (JJS) and percutaneous nephrostomies (PN) on ureteric motility and artificial stone transit was assessed in 12 dogs. Each animal underwent bilateral nephrostomies and an artificial stone insertion into each upper ureter (n = 20). A 4-Fr JJS was inserted on one side (group 1) while a PN was left on the contralateral side (group 2). In 4 stone-only 'control' ureters (group 3), the PN was sealed after 72 h. Stone passage was assessed by plain x-rays. Pelvic and ureteric motility was assessed prior to stone insertion and again at 2 weeks. RESULTS In group 1, only 1 of 8 stones (12.5%) passed completely. Four reached the midureter, 3 remained static. Six of 8 stones (75%) in group 2 passed completely. Two stones remained in the distal ureter. All 4 stones (100%) in group 3 passed by day 3 postoperatively. At laparotomy the J-stented ureters were dilated and both pelvic and ureteric contractions were diminished. Ureteric diameter was normal on the PN side. The ureters contracted with normal amplitude, but diminished rate of contraction above the stones in the ureters with residual calculi (n = 2), and in the 6 ureters from which spontaneous stone passage had occurred. A similar pattern was found in the 4 group 3 ureters. CONCLUSIONS Double J stents are associated with ureteric dilatation, diminished peristalsis and impaired stone passage. APN preserves ureteric peristalsis and facilitates stone passage. In the initial phase, raised hydrostatic pressure appears to the most important factor determining stone passage.

Abstract
OBJECTIVES To compare treatment outcomes in symptomatic and incidental renal cell carcinoma (RCC) with specific interest in the role of radical nephrectomy. PATIENTS AND METHODS The records of 189 patients with a clinical diagnosis of RCC were reviewed. The mode of presentation, tumour size, grade and stage at presentation were correlated with final outcome, as measured by the disease-free and overall survival of the patients. RESULTS The rate of incidental detection was 15%; incidental tumours were of a lower stage and patients with incidentally detected tumours had a significantly longer disease-free and overall survival than had those with symptomatic tumours (P < 0.05). CONCLUSIONS The increased detection of incidental tumours should further improve survival in RCC. We continue to advocate radical nephrectomy for incidentally detected tumours, as it offers the best outcome and simplifies the follow-up.

Abstract
Between 1965 and 1989, 1180 patients at Indiana University, U.S.A., underwent retroperitoneal lymph node dissection (RPLND) for non-seminomatous germ cell (NSGC) testis cancer of whom 638 cases had primary RPLND. A subset of 174 cases were considered clinical stage B (or II) before surgery (retroperitoneal nodal metastases by clinical staging). Surgery revealed that 23% (n = 41) had pathological stage A disease (no cancerous nodes). This error rate in clinical staging has decreased somewhat with improved techniques, but remains approximately 20% over the last decade. The relapse rate in pathological stage A (n = 41) was 5% (n = 2), both of whom were cured by chemotherapy. The relapse rate in pathological stage B without postoperative adjuvant treatment (n = 54) was 35% (n = 19); 2 patients died. This indicates that 65% of pathological stage B cases were cured by RPLND alone. From 1979 to 1989, the 140 pathological stage B cases participated in a randomised prospective trial of post-RPLND adjuvant chemotherapy versus no postoperative treatment. Forty two per cent (n = 59) received postoperative platinum-based therapy (two cycles), and there has been no relapse after RPLND for stage B disease. While advances in chemotherapy for NSGC testis cancer have led to its application by several study groups to clinical stage B (or II) testis cancer (with surgery reserved only for those in partial remission), the equivalent cure rate with RPLND surgery with chemotherapy rescue reserved for those who relapse appears to have both cost and risk-benefit advantages.

Abstract
Between 1965 and 1989, 1,180 patients underwent retroperitoneal lymph node dissection for nonseminomatous germ cell testis cancer (638 underwent primary dissection). Of these patients, 174 were considered to have clinical stage B disease preoperatively (suspected retroperitoneal node metastases by clinical staging). Surgery revealed that 41 patients (23%) actually had pathological stage A disease (no cancerous nodes). This nonspecificity in clinical staging remains consistent despite advance in clinical staging methods during this 25-year period. Of the pathological stage B cancer patients 65% were cured by retroperitoneal lymph node dissection alone. These long-term data indicate that primary retroperitoneal lymph node dissection for low stage metastatic nonseminomatous germ cell testis cancer (pathological stage B) not only had diagnostic but also therapeutic impact. Furthermore, this cure rate with long-term followup is equivalent to that of current series of primary chemotherapy alone for stage B disease, which are still relatively early reports. This cure rate with single modality therapy (retroperitoneal lymph node dissection alone) was accomplished within an average of 4 hours and, therefore, should be more time and cost-effective than prior reports of 3 and 4 courses of primary chemotherapy. In the post-cisplatin era (1979 to 1989), 140 patients with clinical stage B disease were treated with primary retroperitoneal lymph node dissection: 32 (23%) had pathological stage A cancer and 2 of them (6%) had relapse. Both patients are currently disease-free with subsequent chemotherapy. Of the remaining 108 patients with pathological stage B disease 49 received no adjuvant chemotherapy and 59 received cisplatin-based adjuvant chemotherapy. Among the former 49 patients 18 (37%) had relapse and 2 died. No patient receiving postoperative cisplatin-based adjuvant chemotherapy had relapse. The overall survival rate in these 140 clinical stage B cancer patients was 98%. There were 3 deaths, only 1 from cancer. The addition of cisplatin-based adjuvant chemotherapy postoperatively has rendered pathological stage B nonseminomatous germ cell testis cancer entirely free of subsequent relapse. Therefore, retroperitoneal lymph node dissection as monotherapy is curative in two-thirds of the patients with stage II disease, while the remaining one-third with progression to clinical relapse can be reliably saved by chemotherapy. Future considerations in selecting therapy for clinical stage II nonseminomatous germ cell testis cancer will be risk-benefit, cost-benefit and quality of life issues. Several cooperative studies will examine these issues, involving European and United States groups.

Abstract
It is generally considered that 'firm' double pigtail ureteric catheters, while easier to insert and less prone to migration, may cause more patient discomfort than the 'softer' variety of stent. Objective support for these perceptions is however lacking. The aim of this study was to compare firm and soft stents regarding their ease of insertion, positional stability, biocompatibility and patient tolerance. 155 patients were randomised to receive 'firm' (polyurethane, n = 78) or 'soft' (Sof-Flex, n = 77) stents. Ease and mode of insertion was recorded at time of initial placement. Positional stability, degree of bladder inflammation, stent encrustation and patient tolerance were recorded at the time of removal. Patient tolerance was assessed by symptom score in double-blind fashion. Results showed no significant difference in ease of insertion, positional stability, degree of bladder inflammation or stent encrustation between the two groups. There was a significantly higher incidence of dysuria, renal and suprapubic pain in the firm stent group. There was no significant difference in the incidence of urgency, frequency, nocturia or haematuria. Normal activity and return to work were reported in 67 and 45% of patients with soft and firm stents, respectively. The data indicates that patient tolerance appears to be related to the softness of the stent material.

Abstract
A total of 42 patients underwent inferior vena cava resection (n = 40) or intraluminal tumor thrombectomy (n = 2) during retroperitoneal lymph-node dissection (RPLND) for bulky abdominal metastatic nonseminomatous germ-cell cancer (7% of all postchemotherapy RPLND cases). The three indications for caval resection included tumor clearance (38%), caval scar occlusion (14%), and caval tumor thrombus (48%). En bloc caval resection to achieve tumor clearance was justified by subsequent nodal pathology (cancer in 63% of specimens, teratoma in 31% specimens). Caval resection in the presence of scar occlusion was required de facto by virtue of its incorporation in the specimen. Caval resection or thrombectomy is indicated for intraluminal tumor thrombus because thrombus pathology (cancer, 35%; teratoma, 45%; fibrosis, 20%) reflected nodal pathology in 71% of cancer cases, 78% of teratoma cases, and 100% of fibrosis cases. The complications of caval resection were generally transitory. The 71% survival rate justifies this intensive surgical approach because these patients had exhausted all chemotherapeutic options.
