RESUMEN

The natural history of benign enlargement of the prostate is variable and ranges from mild symptoms to chronic retention and renal failure. In this study, the outcomes of patients with urinary retention alone were compared with those of chronic retention and renal failure caused by an enlarged prostate. The first group had 79, while the second group had 20 patients included. The mean maximum flow rate after transurethral resection of the prostate (TURP) in the two groups was 16.9 ± 7.9 vs. 14.6 ± 4.1 ml/sec (p value > 0.05), and the mean post-void volume was 15.1 ± 27.6 vs. 21.7 ± 35.7 ml (p value > 0.05), respectively. However, the residual symptoms after surgery were higher in the chronic retention group. It was concluded that patients, with chronic retention experience and higher postoperative residual storage symptoms, after transurethral resection of the prostate, are able to void without a catheter and their renal functions were stabilised. Key Words: Transurethral resection of the prostate, Prostatic hyperplasia, Renal insufficiency, Urinary bladder neck obstruction.

RESUMEN

To report a case of chondrosarcoma of right big toe with left orbital and left infra temporal metastases. Chondrosarcoma is the second most frequent primary malignant tumour of the bone. A 56 year old man had history of trauma on his right big toe, which was amputated and the biopsy in 2011 at Sindh Institute of Urology and Transplantation (SIUT) revealed chondrosarcoma with clear margins. Eventually the patient was presented with swelling of the left eye, pain and gradual loss of vision of that eye. Later a CT scan of his chest, brain and orbit showed pulmonary and pleural based nodule, with mediastinal and hilar lymphadenopathy representing metastatic deposit in left orbit, extending to left infra temporal region. A treatment of palliative chemotherapy was started with doxorubicin and ifosfamide, after which he was referred for radiotherapy. At that time he had loss of vision, pain and exopthalamus, and palliative radiotherapy was delivered to the left orbit with the prescribed dose of30 Gy/300cGy×10 fraction. Thereafter his case will be followed up at the oncology OPD after a 03 month interval.

RESUMEN

OBJECTIVES: Laparoscopic donor nephrectomy has become the criterion standard for kidney retrieval from living donors. There is no information on the experience and outcomes of laparoscopic donor nephrectomy in Pakistan. The objective of the study was to identify benefits and harms of using laparoscopic compared with open nephrectomy techniques for renal allograft retrieval. MATERIALS AND METHODS: In this a retrospective study, patient files from May 2014 to September 2015 were analyzed. Patients were divided into 2 groups: those with open donor nephrectomy and those with laparoscopic donor nephrectomy. Donor case files and operative notes were analyzed for age, sex, laterality, body mass index, warm ischemia time, perioperative and postoperative complications, surgery time, and length of hospital stay. Finally, serum creatinine patterns of both donors and recipients were analyzed. Data were analyzed using SPSS version 10 (SPSS: An IBM Company, IBM Corporation, Armonk, NY, USA). RESULTS: Of 388 total donors, 190 (49%) had open donor nephrectomy and 198 (51%) had laparoscopic donor nephrectomy. For both groups, most donors were older than 25 years with male preponderance. Left-to-right kidney donation ratio was markedly higher in the laparoscopic group than in the open donor nephrectomy group, with 6 cases of double renal artery also included in this study. There were no significant differences in surgery times between the 2 groups, whereas the laparoscopic donor nephrectomy group had shorter hospital stay. Analgesic requirements were markedly shorter in the laparoscopic donor nephrectomy group. The 1-year graft function was not significantly different between the 2 groups. CONCLUSIONS: The results for laparoscopic donor nephrectomy were comparable to those for open donor nephrectomy, and its acceptability was high. Laparoscopic donor nephrectomy should be the preferred approach for procuring the kidney graft.

RESUMEN

PURPOSE: To determine the pattern and outcome of renal tumors in young adults in a large surgical series in Pakistan. MATERIALS AND METHODS: We retrospectively analyzed 133 young adults (age: ≥ 16 to ≤ 40 years) with 136 renal tumors, who underwent surgical treatment for suspected renal cancer from 1994 till 2010. The clinical and pathological parameters were determined and their impact on final outcome was analyzed. RESULTS: The mean age of the patients was 33.3 ± 6.2 years. Of 136, 121 (88.9%) renal tumors were malignant and 15 (11%) were benign. Among malignancies, 76 (62.7%) patients had stage I or II tumors, 22 (18.1%) stage III, and 23 (19%) stage IV at surgery. The overall cancer-specific survival for malignant tumors at 1, 5, and 10 years was 97%, 83%, and 83%, whereas the cancer-free survival (CFS) was 80%, 63%, and 37%, respectively. Patients with age ≤ 35 years had 1 and 5-year CFS of 83% and 71%, respectively, as compared with 76% and 49% for patients > 35 years (P = .02; odds ratio = 2.3; P = .03). Regarding tumor size, 1 and 5-year CFS for tumors ≤ 10 cm was 93% and 75%, while tumors > 10 cm showed CFS of 56% and 41%, respectively (P = .0001; odds ratio = 4.2; P = .0001). For stage I tumors, CFS at 1 and 5 years was 98% and 84%; for stage II, 82% and 63%; and for stage III, 62% and 50%,respectively. One-year survival for stage IV was 48% only (P = .0001). CONCLUSION: A wide heterogeneity of renal tumors is seen in young adults with delayed presentation.

RESUMEN

Peripheral primitive neuroectodermal tumor/Ewing's sarcoma (PNET/EWS) is primarily a tumor of soft tissues and bones. Primary localization of PNET/EWS in genitourinary organs is rare. No data on this localization of PNET/EWS are available in literature from Pakistan. We searched our adult uro-oncology records from 1994 till date and identified all cases of adult genitourinary and adrenal PNET/EWS diagnosed on histology and immunohistochemistry. Their case records were reviewed to obtain data on demographics, presentation, pathologic features, management and outcome. Six cases were found; all were young and had aggressive disease at presentation. Four had renal PNET/EWS. One case each of prostate and adrenal PNET/EWS was seen. Surgery and chemotherapy formed the mainstay of management. Three patients (50%) died during treatment, two were lost to follow-up and one case with renal PNET/EWS showed good initial response to chemotherapy but was later on lost to follow-up. In conclusion, PNET/EWS should be considered in the differential diagnosis of genitourinary malignant tumors in young patients. These tumors are aggressive with poor outcome.

RESUMEN

OBJECTIVE: To compare the outcome of Extra corporeal shockwave lithotripsy for a renal pelvic stone with and without JJ stent. METHODS: A comparative cross sectional study was carried out at Sindh Institute of Urology and Transplantation from January 2007 to January 2008. Eighty patients with renal pelvic stone measuring 2cm +/- 2mm were selected for treatment with Extra Corporeal Shockwave Lithotripsy (ESWL). All of these patients were adults with normal renal function and had unilateral renal stones with negative urine cultures. Patients with renal failure and children were excluded. They were divided into two groups of 40 each. Group A patients underwent ESWL without a JJ stent and in Group B a JJ stent was placed before ESWL. SLX F2 electromagnetic ESWL machine was used to impart shock waves. 3000 shockwaves were given in a session. Both the groups were compared for renal colic, steinstrasse, fever, lower urinary tract symptoms (LUTS) emergency room visits and hospital admissions, stone clearance, number of ESWL sessions, auxilliary procedures, (percutaneous nephrostomy or ureterorenoscopy) and cost. RESULTS: Ureteric colic occurred in 13 (32.5%) patients in group A and in 3 (7.5%) patient in group B. Steinstrasse developed in 4 (10%) patients with out JJ stent and in 3 (7.5%) patients with JJ stent. Fever was encountered in 1 (2.5%) patient in group A and in 3 (7.5%) patient in group B. Mean emergency room visits were 2.1 per patient in group A and 0.7 per patient in group B. Stone clearance occurred in 33 (82.5%) patients in group A and 31 (77.5%) in group B. In group B lower urinary tract symptoms were found in 50% versus 20% in group A. Auxillary procedure was performed in one (2.5%) patient each in both groups. CONCLUSION: Pre ESWL JJ stenting for a 2 cm +/- 2 mm renal stone was not beneficial in terms of steinstrasse, fever, stone clearance and number of ESWL sessions. However ureteric colic was significantly less in the stented group. Lower urinary tract symptoms (LUTS) was also significantly high in the patients having a JJ stent. The cost of the treatment doubled in the stented group which is an important factor in our country. JJ stenting does not prove to be a cost effective procedure when compared to the reduction in complications.
