Renal growth after neonatal urinary tract infection

This study presents the result of 12–21 years' follow-up in a group of children with neonatal urinary tract infection (onset within 1 month after birth) in whom early renal growth retardation was noted without concomitant classical renal scarring. In all cases the neonatal infection was diagnosed and treated within a few days of onset and the patients were closely supervised thereafter. Renal length, parenchymal thickness and area were measured at urography. At first follow-up (22 children, mean age 4.1 years) a significant reduction of renal parenchymal thickness was noted. Long-term follow-up (18 patients, mean age 17 years) demonstrated a normalization of renal size in the entire group, although less complete in the subgroup with reflux. There were two major findings in the present study. Firstly, renal growth retardation was seen after neonatal infection, both with and without reflux. Secondly, normalization of renal size in previously small kidneys was demonstrated, suggesting that growth retardation can be a reversible phenomenon. The tendency for such normalization was slightly more marked in children without reflux. Reduction of parenchymal thickness without calyceal deformity, therefore, does not necessarily mean irreversible damage, and differentiation between permanent scarring and temporary growth retardation can thus only be made at later follow-up, possibly not until after puberty. The demonstration of renal growth retardation in spite of early diagnosis and treatment emphasizes the great vulnerability of the kidney in the newborn.

膀胱癌的MRI诊断价值

目的:总结膀胱癌的MRI征象,探讨MRI对膀胱癌分期的作用及鉴别诊断要点。方法:对探讨经手术与病理证实23例膀胱癌的MRI回顾性对比分析。其中男性,19例,女性,4例,年龄50~90岁,平均年龄70岁。18例行MRI增强检查。结果:膀胱三角区及膀胱后侧壁是最常见好发部位,表现为膀胱壁突向腔内肿块和(或)膀胱壁局限性不规则增厚;肿瘤平扫T1WI等或略高信号,T2WI呈高信号,Gd-DTPA动态增强早期肿块显著强化。根椐肿瘤生长方式可分为:①小结节型,②广基肿块型,③浸润型。MRI对膀胱癌定位、定性诊断正确率分别为95.7%(22/23)、91.3%(21/23);术前MRI诊断与TNM分期符合率为82.3%(19/23),MRI较病理分期偏高。结论:膀胱癌的MRI表现具有独特性。T1加权主要用于肿瘤的定性诊断,T2加权主要用于肿瘤的术前分期;MRI检查多方位、多序列成像,是显示膀胱癌最理想的检查方法。     

保留盆腔植物神经对老年男性患者术后性功能及排尿功能的影响

目的:探讨保留盆腔植物神经的直肠癌手术对老年男性患者性功能及排尿功能的影响。方法:1999~2005年因直肠癌手术的170例老年男性患者分为PANP组(含规范的TME手术方法)和非PANP(TME规范情况不详),对两组术后性功能、排尿功能和局部复发率进行回顾性总结、比较。结果:PANP组性功能与排尿功能明显优于非PANP组,但统计学无显著差异(P<0.05)。而PANP组局部复发率低于非PANP组(P>0.05)。结论:老年直肠癌患者应重视性功能和排尿功能的保护。

Urinary bladder carcinoma producing granulocyte colony stimulating factor (G-CSF): A case report with immunohistochemistry

A rare case of urinary bladder carcinoma with granulocyte colony stimulating factor (G-CSF) production was reported. In an 83-year-old female, marked neutrophilia in the peripheral blood decreased from 132,500/mm³ to 3,300/mm³ after tumour resection. The tumour was a transitional cell carcinoma. The serum G-CSF level reduced from 238 pg/ml pre-operatively to normal (60 pg/ml) after the operation. Immunohistochemical investigation of the resected tumour with monoclonal antibody specific for G-CSF revealed positive staining in the carcinoma cells, confirming G-CSF secretion.

Dysgeusia related to urinary obstruction from benign prostatic disease: a case control and qualitative study

Anecdotal reports suggest that dysgeusia may be related to a variety of systemic factors, including bladder outflow obstruction. This is a hospital-based case-controlled study involving 111 patients who were admitted to urological wards for transurethral resection of the prostate for benign prostatic disease with age- and sex-matched control of 137 subjects. We used a semi-structured questionnaire by a trained interviewer at admission (preoperative), at the postoperative period and at follow-up between 4–6 months (median 5 months). Analysis used unpaired t-test and X₂ test. The incidence of dysgeusia was 22% in the study group and 13% in the control group (P=N.S.). However, strikingly, the dysgeusia in the study group was relieved promptly by relief of urinary obstruction in 100% of cases and did not return within the follow-up period. The mechanism of the dysgeusia associated with dysuria in benign prostatic disease is unknown, but we suggest that the dysgeusia could be from the stress of dysuria or due to a release of an unknown chemical from the urinary tract or an overflow of neural impulse from pontine/cortical micturition centres to the taste centres. An association between dysgeusia and dysuria has not been described before.
